Cannas are among the most colorful summer bulbs—as flamboyant as their tropical American ancestry—with ruffled spikes tapering to refined buds.

These perennials come in a vast variety of color and boast immense, often-veined, paddle-shaped leaves and sheathing leafstalks in shades of green or bronze.

With their great reedy canes and palmy foliage, cannas would be magnificent even if they never bloomed. However, they keep blossoming from late spring or early summer to frost.

Turn-of-the-century gardeners so loved cannas that they grew them from seed but this isn't easy; better to leave propagation to experts and buy the tubers.

Planting

  • Exotic, tropical creatures, cannas need lots of sunshine and fertile, moist soil but you don't have to pamper them.
  • Cannas can be started in the house in small pots if your gardening season is short.
  • Where not hardy, plant outdoors in early summer—around the same time you'd put in tomato plants.
  • To plant, loosen the soil to a depth of 12 to 15 inches, then mix in a 2- to 4-inch layer of compost.
  • Dig a hole 2 to 3 inches deep and set the rhizome in the hole, eyes up.
  • Cover with soil and tamp firmly. Water thoroughly.
  • Space rhizomes 1 to 4 feet apart.
  • If you grow from seed, note that the germination rate is low and the seeds need to be filed or given an acid bath to break down their hard coat.

Care

  • Cannas do best with a good supply of water, so water the plants during the summer if the rainfall is less than 1 inch per week. Water freely in a dry spell.
  • Keep a thin layer of mulch around cannas to help retain moisture as well.
  • Stake tall varieties if needed.
  • As flowers fade, deadhead to promote continued flowering.
  • Cut each stem to ground after bloom.
  • After autumn frost blackens the foliage, remove the stems and leaves, and lift the rhizomes for winter storage. Store in barely-moist peat or leaf mold in frost-free conditions. Space rhizomes so that they are not touching.
  • In the deep South, let cannas grow without moving them, until the clumps grow very matted. Every 3 to 4 years in the winter, dig up the clumps, separate the roots, and plant them in well-enriched soil.
  • Some gardeners as low as zone 7 have reported that their cannas are getting through the winter without being dug up; just be sure to protect the tubers with a heavy layer of mulch.

Pests

  • Slugs, snails, spider mites, and caterpillars may be problems.
  • Rust, fungal leaf spot, and bacterial blight are common.
  • Bean yellow mosaic and tomato spotted wilt viruses can occur.

Harvest/Storage

  • If you are storing cannas over the winter, store in a dry place at 45 to 50 degrees F. Don't let them dry out; sprinkle the sand or soil around them, if necessary.
  • In the spring, cut the tubers apart with a sharp knife so that each piece contains one eye on a substantial piece of rootstock.

Recommended Varieties

  • Dwarf cannas stay under 3 feet tall and are easy to fit into our downsized modern gardens. The 2-1/2-foot-tall 'Picasso' is a yellow-flowered dwarf peppered with freckles.
  • Standard varieties grow 4 to 6 feet tall and need a 20- to 24-inch circle for each hand-size rhizome. 'The President' is  is red, 'Yellow King Humbert' spotless, 'Rosamond Cole' orange-edged gold, and 'City of Portland' salmon pink.
  • Many gardeners love the spectacular, drought-tolerant varieties that reach heights of over 6 feet. One gem is the rich, deep pink 'Los Angeles', which has a large floret and opens out so that you can see the face.
  • 'Bengal Tiger' is stunning even when it's not blooming with green-and-yellow-striped, maroon-edged leaves and bright-orange flowers.

My experience in California is they grow like weeds, I don't know if that is different in your area. I'm no expert, but if they were mine I would just continue to water them and they will grow.

I've only seen pictures online what they look like, the lady I bought them from had said she had already cut hers down at that time and that's how she had roots for sale.

I bought my canna at Walmart. They are yellow with the red speckles on them. I will be planting them mid april 2014. Is it best to plant them away from other flowers? I do not want them to multiply over time and suffocate my other flowers. How far apart should I plant them?

By Almanac Staff on April 9

Canna do spread so if you're concerned, we would plant canna in their own garden bed. We're not sure where you live, but cannas are generally dug up annually and stored anyways. You can always dig up the clumps, keep what you wish, and give some of them away!  Another solution is to plant canna in containers to control the spread. Some folks even sink the containers into the ground.

Good morning to you. I am in Jamaica West Indies. Thanks for your comments to persons like myself. I am contemplating growing cannas as a business opportunity. Can you suggest sources from which I could procure seeds of the various varieties that I have seen in pictures? I would not consider importating rhizomes because of the complications and hassle when one has to import live plants. I do understand the reason for the qurantine and other safety measures. Your prompt response would be greatly appreciated.

I am in Dallas Ga. and I had left mine in the pot that they came in over the winter. Pushed the pot under the table I had put all my plants on for winter and totally forgot about them. Three or four days ago I decided to take all the plants outside and when it came to that pot I decided to dig it up to see if there was anything left. They were in great shape,and had already started to sprout. I think as the days are getting warmer they will soon began to sprout and in a week or two you might began to see them come up. I hope this was helpful.

Thank you for your quick response to my previous question however I am worried that I might have planted my cannas bulb to deep,will they still come up or will they die? I have tried to plant cannas before and they never did come up. Thank you in advance.

Our souces suggest plannting

By Almanac Staff on April 4

Our souces suggest plannting cannas about 4 inches deep, laying them horizontally, with eyes up (if you can find the eyes) in rich, most moisture-retentive soil. Fertlize when you plant with a balanced mix (or per the instructions on the canna packaging) and once a month in the summer.
Some cannas a bog plants and thrive along water banks, other merely desire "wet feet."
Watch for slugs when the shoots emerge. (Could these have already attacked your canna?)

By dwighttovey

I'm in Boise, ID (Zone 7) and my wife and I have been growing Tropicanna Black cannas for a couple years. We dig up the tubers in the fall and replant in the spring. The weather has been warming up recently so we were considering getting them back into the planters, but when I went to check on them, I found that while new sprouts have already started (about 6-8" already), there is some white fuzzy mold on some of the rhizomes. Apparently it was too moist in the tubs that we had them stored in? Any thoughts on the impact of that mold? Will I contaminate the soil if I plant anyway? Will it damage the plants any? Should I leave them uncovered for a while and hope that the mold dries out and dies?

Thanks for any comments.

A cottony, fuzzy growth on

By Almanac Staff

A cottony, fuzzy growth on the rhizomes could be rhizome rot, a fungal disease caused by Sclerotium rolfsii or various species of Fusarium. It can appear in humid, damp conditions.
 
If you think this is what your rhizomes have, then you can either discard the rhizomes, or perhaps try dipping the rhizomes in a solution of 1 part bleach to 9 parts water (not sure how this will affect growing shoots, though). Dip them just one or two times to try to remove the mold. If they are still moldy, or if they show other signs of disease, such as sunken or mushy or black areas, then discard them. Otherwise, after the dip, dry them with a cloth, and then set them out to dry for a few days in an area above 50 degrees F. You might also separate these plants from others if you grow them outside, just in case they still do have remnants of disease.
 
When you store them next year, dry them for a few days before storing, and you might try dusting them with an appropriate fungicide (a garden center can advise you about products) to discourage the growth of mold. Don't store in airtight containers; allow adequate air circulation. Keep them dry, dark, and cool, but not freezing.

The best way to keep Canna

By Almanac Staff

The best way to keep Canna under control are to lift the plants, even if you live in the south and don't need to. The roots should be divided in the spring. (Give some away to friends!) Also, canna will form seed if the blooms are not dead headed so remove the spent flowers to keep cannas under control.

By Rex Marble

I bought plants from nursery last year. Dug up rhizomes for winter because of freezing. I will start the plants this spring in pots and replant in flower beds later. What is the preferred mixture for the pots? 100% potting mix, 50/50 soil potting mix, or another blend?

Start canna rhizomes indoors

Start canna rhizomes indoors 4 to 6 weeks before the average last frost date in your area.  Plant the cannas in large pots.  The rhizomes should be covered with 3 to 4 inches of potting soil.

By Laura Reno

I live in Central Mo and have a yellow water canna that I have had in a container water garden in the summer. This is the second summer I have brought it in (this fall I had to cut it out of the pot and put it in a large plastic cat litter container) and left it, in water, couple inches over top of dirt/clay line.
My question is - should I let it dry out some or somehow put something under it for drainage - the leaves keep turning brown on the tips, then dying. However, the only time it has bloomed WAS inside. I have never dried it out and wintered it over that way. Only kept as water plant indoors in a window. Now, with the water down below the clay line... I see new growth coming out....

Please advise,

It's already in moist soil/clay/rock... I figured I would leave it in the bathroom, where there is a bit more light and not directly above the heating vent and that might help.

By Almanac Staff

Cannas are hardy in the far southern and western counties of the state. If you are in zone 7a (see zone map: http://planthardiness.ars.usda.gov/PHZMWeb/) , you may be able to get away without digging them up.  However, if you want to be sure they'll survive, you need to dig up the rhizomes after a heavy frost. See information above. You can store them and then replant them in the location you prefer in early summer!

By Griz

I have canna's (about twelve years now) that have bloomed in the past, but haven't bloomed for the last couple of years. The rhizomes do multiply profusely each year and the foliage is dark green and healthy. I seem to plant them too late, July, each year. Located in southwest PA. I have always used bone meal and osmocote fertilizer when planting....is this wrong? What type of fertilizer works best? Do canna prefer a basic or acidic soil ph? Thanks in advance for your advice. I want next season to be my best for blooms!

If the foliage is healthy,

By Almanac Staff

If the foliage is healthy, the lack of bloom is 90% of the time because the cannas are not getting enough direct sunlight.
Or, they need more nourishment. Cannas are very heavy feeders. Any good, well-worked soil will do but it needs to be rich in organic matter; adding fertilizer or amendments on top is not enough. Try conditioning your garden soil with a heavy dressing of manure or compost. Fertilize in mid-season with a good general fertilizer. Are you properly digging up the tubers and storing them in the winter?  Try starting your tubers indoors in containers in a warmer atmosphere before putting them in ground.

Yellow leaves are usually a sign of overwatering. Also, canna leaves go yellow when the plant is in a dormant or rest state.
As you suggest it's a watering issue, allow the soil to become dry, but keep it from drying completely with an occasional light watering.

Canna lilies are native to the tropics and subtropics, so they're a bit dried out and use to more humidity. Water deeply and slowly at the soil level; don't sprinkle. Also, water thoroughly before and after applying fertilizer to help prevent burn.

You can use moist peatmoss for storing or just sprinkle a bit of water on the bulbs during the winter months. The best place to store cannas is a cool basement or a garage. If the area is too cold you can cover the box or bag with a blanket.

By BJP

I live in Central Florida and have 3 orange cannas that we bought last year which flowered continously during the summer/fall. Over the winter, they declined and I cut them down nearly to the ground. This spring they grew back but have barely flowered and the leaves have been browning and dying constantly even though there is also new growth occuring regularly. I don't remember that much browning last year.

I checked for bugs and can't see anything. I have only fetilized them a couple of times with a 6-6-6 slow release product. I water them only occasionally because we have gotten a fair amount of rain this summer. Last year, I know I watered them more often.

Aside from the dirt they were planted in when I bought them, they are essentially planted in sand.

What can I try to fix whatever the problem might be and get them start flowering and stop the leaves from dying?

By Almanac Staff

Cannas are winter hardy in zones 7 through 10.
So, it depends on where you live in Maryland. See the USDA Plant Hardiness Zone Map to find your zone in Maryland: http://planthardiness.ars.usda.gov/PHZMWeb/
After your first killing frost, dig a foot away from the stem and gently loose the soil to dig up the clump out of the ground. Wash the roots off with a spray of water. Cut off the tops of the Canna Lilies and add them to your compost pile. Store the rhizomes  them in a peatmoss, vermiculite, or perlite. Punch holes in it for air circulation. The rhizomes should not dry and shrivel during storage.

So some of my cannas starting to grow and some are not I have them spread all around my home, front yard back and sides, I did not dig them out last winter because I read in my zone if I layer well with mulch and cut the tubes they should be fine, not sure why they are not starting to grow at same time or even if they will even all come back?

Some of your cannas may be getting more sun than others. Give them a little time and they should all come back.

If you didn't mulch them well they may not come back. They are cold hardy in Zones 7-11.

Canna Lily care central Wisconsin

By Anonymous

I have at least 15 bulbs that I have stored in brown paper bag. These were given to me. They came from very hard clay soil in southern Indiana. I live close to Wisconsin Dells area or an hour north of Madison. My soil is sandy. They will be planted on south side of my home. The Canna's would receive 8-10 hours of sunlight per day.I'm planting them to act as a privacy fence for our pool.

My 10 day forecast ranges from 36-70 for highs and lows from 39-57. That is for first 8 days in May. Can I plant them out side would it be safe? They will have Caster Bean plants between them.

Could I stake a clear bag for added protection and warmth. I could also, cover with straw/hay/leaves if needed. I'm worried if not planted soon we will not see them grow to full potential. I have a mix from red to variegated variety. Any suggestions and tips are greatly welcomed. Thank you for anyone who replies to my questions. :)

My cannas were already up pretty good. Last night, they got a heavy frost and are all brown. Should I mow them down for a fresh start, or leave them be? It is springtime in Texas.

Cannas are hearty, but a frost will kill the stalks. Remove the dead stalks to the compost pile, but you can leave the rhizomes in the ground and they will shoot up again in the spring. Add a good layer of mulch to keep the roots from freezing.

Help with my Grandma's cannas please.

By Anonymous

I live in northern Alabama(zone 7 I think), and received many cannas after my Gramndmothers passing. I was under the impression that you couldn't really kill a canna, so I dug them up from her yard, bulbs and all, and replanted them in my yard. No problem. This was two summers ago. When fall came around I cut them off at the ground, removed many bulbs from the soil, planted Pansy's, and put down a layer of mulch. This past summer they didn't grow very tall or bloom til late in the summer. I haven't cut them off this year, only put down several inches of leaf mulch around the stalks. This is the red flower/green leaf variety and now I am afraid they won't make it thru the winter. I will be very upset if I lose them and don't know what my next move should be.

Your Grandmother's cannas

By Anonymous

Hi, I live in Coastal SC, zones 8 & 9(I'm right on the border :) I would think your cannas are hardy there where you live, but I'm wondering if they are getting plenty of sun and water. I have planted cannas in many different places in my yard and also where I used to live, and most of them thrive the best if they are in a sunny location. This year I had one placed where it got sun from dawn till dusk and it bloomed on December 15 even! :) Also maybe consider a little fertilizer, the liquid type. Maybe also have your soil tested. I don't know how old this post is, but just offering some ideas :)

canna troubles

By Almanac Staff

Cannas may be stunted or bloom poorly if they receive less than 6 hours of sunlight per day. Make sure that the soil is fertile and consistently moist. Remove spent flowers to encourage more blooms. High temperatures can also stress to the plant, often resulting in shorter growth that year; be sure to keep up with the watering at these times.

Check for signs of pests/diseases, which can affect growth and flowering. For example, canna mosaic virus (also called bean yellow mosaic virus) can cause stunted growth, late flowering, and yellow streaks on leaves.

Your county's cooperative extension can give you guidelines as to proper canna care for your area, and may be able to test for viruses (for a fee) or refer you to a lab that can. For contact information, see: http://www.almanac.com/content/cooperative-extension-services and select your state.

Hope this helps!

By Mad

I don't find that Cannas need a lot of sun. Those I have planted in dappled shade are doing well, while the ones on the other side of my property in the sun have bloomed less and less each year and also look very stunted. I water them frequently so I don't know why they aren't growing as well as those in shade.

Bulb?

I have many, many what it appears to be bulbs, growing from my canna stalks and rhizomes since I have pruned the cannas for winter.They have probably been there for some time, but I did not notice until I cut the canna stalks.

Do I need to remove my cannas after frost if I live in Northwest Arkanasas

canna hardiness

By Almanac Staff

The USDA Hardiness Zones for northwest Arkansas are 6 and 7. Most cannas are hardy to Zone 8, although a few can survive in Zone 7. It would probably be best to dig up your cannas in fall and store them over winter, especially if you are in Zone 6. (A local nursery might know what Zone you are in.) See above for more details about how to overwinter cannas.

PA - zone 5

By Anonymous

Hi - I planted 8 cannas over the summer because the tag said they were perennials. I am not sure how to get them ready for the winter, and I was hoping to keep them in the ground. How many inches should I leave on the plant for the winter, or do I absolutely have to dig them all up and store them? Thank you!!

Canna bulbs

By Anonymous

Living outside of KC, zone 5b, where the woman across the street planted maybe a dozen bulbs in the spring and then dug them up each fall. She moved 5 years ago, leaving the bulbs behind and in the ground.
They were not removed from the ground for 5 winters now and they have multiplied and continued to spread out across the south facing brick wall against which they were originally planted.
The new tenant did not want them and offered the bulbs to me. I now have 3 grocery sacks of bulbs to store this winter.
But, given what I observed, I plan to treat them as a perennial and leave them in the ground. Perhaps thinning them periodically in the fall.

After the first frosts which

By Almanac Staff

After the first frosts which kill the foliage, carefully cut off the tops and dig up the roots with a spade or fork. Brush off the soil. Let them dry in a warm place for 7 to 14 days--about 45 to 50 degrees F. Make sure it's not too cold! The corner of a basement is often good. Then, store in an open container or cardboard box amidst shredded newspaper. Or, hang in a mesh bag. The key is to allow circulating air; do not put in a closed container. You can replant each clump in the spring.

Canna conundrum

By Almanac Staff

Lucky you in a frost-free zone! You can prune the old or spent foliage from your cannas any time. That allows new growth to come in. Some advise cutting the old growth (flowering stalks) when the new ones come in. While you do not have to "lift" and overwinter your bulbs, you should be prepared to lift and then them once a year or every two to three years; it depends on their vigor and the degree to which they are crowded. (You would thin them to eliminate the crowding.) Even if you thin them occasionally, you cannot hurt them. We hope this helps!

cannas seeds

The seeds that come on these plants can u plant them and start new plants since there origanlly started from a bulb?

You can plant the seeds. Save

By Almanac Staff

You can plant the seeds. Save the seeds and plant them indoors 10-12 weeks before your last frost in the spring. The seeds have a hard covering that you need break before planting. Use sandpaper to sand one end of the seed until you see the white inside. Soak the seeds overnight and plant in flats or small pots. Keep in a warm spot. Transplant the seedlings to bigger pots before planting them outside when the weather has warmed up. Cannas do not come true from seed. You will have flowers but they will not look like the ones on the parent plant.

overwintering for two years

By Anonymous

I have a lot of tall, thriving cannas that I dug up and wintered last year and am about to do so for this winter as well. However, next fall, I won't be home for the entire season. Will the cannas last without being planted for two summer seasons? Would it be better to plant them and then not dig them up in the fall and have them take their chances in the hard ground for most of the winter while I'm gone? I live in the Czech Republic, so cold winters.

over overwintering cannas

By Anonymous

There is no easy answer to this. You risk losing these bulbs with either one. All of our sources suggest, strongly, that cannas will not survive a harsh winter in the ground. It seems like you know that. Our advice is not to leave them in the ground for the period you describe. If the cold doesn't get them, the wet (melt and potential refreeze of a normal winter, and rain) might. However, if you try this, mulch heavily. Will they survive two summers, effectively in storage (not in the ground)? That is a question that is seldom asked, so our best response is "not likely." The bulbs store the food for the next season. If the bulbs sit on a shelf or in peat or whatever, they will dry out, and the food would be used up, or wasted, over the course of time that you describe. Do you have a friend who could store them, plant them (and enjoy them), and then store them (and plant, if nec.) again?? We hope this helps.

Canna question

By Anonymous

I received a canna plant from my daughter in early September. I live in NE Wisconsin and not sure if I can plant in a pot and keep in house over the winter or if I should put in my basement and keep watered so it can "sleep". When I plant next year should I dig up in the fall and bring indoors?

After the first frost dig up

By Almanac Staff

After the first frost dig up the canna bulbs and cut off the foliage to about 2-3 inches from the bulb. Place the bulbs in a dry area to "cure" for a couple of days. Then wrap the bulbs in newspaper and store in a cool, dry place for the winter. Do not water. In the spring plant outside and then dig up in the fall.

Flower Troubles

By Almanac Staff

It sounds like your cannas have plenty of sun and rich soil. If this is the first year in which they were transplanted, then they might be waiting to bloom in the following year. Sometimes it takes a year for transplanted cannas to get comfy in their new home before they concentrate their energy on flowering, especially any divisions with just 1 eye. Other causes might be: rhizomes are planted too deep (no more than 3 or 4 inches deep) or the rhizomes are overcrowded (space them 1 to 4 feet apart).

Colorful cannas are a

By Almanac Staff

Colorful cannas are a stunning addition to any landscape! I envy you. I canna think of a reason to “lift” (remove from the soil before winter) your cannas now, if they have been in the ground for 2 ½ years and are growing and blooming successfully. If you want to thin them, of course, you need to lift them—at least for the time it takes to divide, or thin, them. As noted above, dividing is best done in spring. Unearth the tubers and, using a sharp, cut the tubers apart, making sure that each piece contains one “eye” on a substantial piece of rootstock. Replant the tubers as you like; give the others to friends as gifts!

Sometimes black leaves are due to overfertilization or too much salt content in the water. Let the soil completely dry out and then water with distilled water. If the leaves do not recover, it may be a pest or disease issue. Bring a sample to your local cooperative extension or garden center for a complete diagnosis.

Need a boost

By Anonymous

I have several areas in my yard of cannas ( Columbia SC). The ones near the house covered in red rock as their mulch, get run off from the roof, and only get 4 hours of morning sun are the best. I never dig them up for the winter. The area around the pool get 6 to 8 hours and they look horrible this year. Usually they grow 5 to 6 feet high like the others, but it is mid July and they are less than knee high. They have mulch at the base I've had them all about 6 years. I make sure they have enough water, but they just aren't growing. Any ideas on what kind of fertilizer I can use?

Since you've grown cannas,

By Almanac Staff

Since you've grown cannas, we'll assume you have enough sun (at least 4 hours) and water.
If they're not growing, here are a couple thoughts 1) Are they getting overcrowded? Separate and divide them. 2) Try pruning after bloom to encourage flower production by cutting the stem beneath the wilted flower. After all flower stems have flowered, prune them all off to avoid seed production which robs the nutrients. 3) Though cannas aren't that picky about soil, they perform better with compost and aged manure. You can also boost the canna with fertilizer monthly--an all-purpose kind will do.

Cannas thrive in MI

By Anonymous

When I moved in to my duplex my neighbor and I had them cover our whole front of our houses. They grow to be six feet! I couldn't handle them covering my front window any longer. At night they looked as if someone was outside peeking in. Especially on a windy night. It has taken me two years of digging to get even a few of the plants to stop growing. I at least uncovered my outdoor faucet and hanging hose from them however they still cover my window. They give me privacy from neighbor kids. ; ) I'm used to them now and they are pretty and I do not even have to maintain them other than under extremely hot conditions and dry spells I water them daily. It helps that they are close to the house and are next to my hose. They are mulched every year and I cut them at the end of fall. Many neighbors have taken bulbs home and have grown their own. So yes they do thrive and are wonderful because they are low maintenance. Good luck flowering!

Tropicanna - Rhizones

By Anonymous

Last year I planted these in a pot outside - after the plant died off, I also removed some of the rhizones thinking that they would not come back the next year, and moved the pot into the garage for the winter. To my pleasant surprise early this Sprint there were approximately 12 stalks growing in the pot. I moved them to my deck and I'm enjoying beautiful flowers all over again. I wish I knew this before I removed the rhyzones - could have a lot more.
