The nasturtium is a cheerful and easy-to-grow flower! Their bold blooms and edible leaves, flowers, and seedpods make them an especially fun flower for kids to plant. Here’s how to grow your own nasturtiums!
About Nasturtiums
These lovely plants, with their unique greenery and vibrant flowers, grow well in containers or as ground cover around vegetable gardens. In fact, they are often used as a trap crop in companion planting, drawing aphids and other garden pests away from the more valuable vegetables.
Pests aren’t the only thing nasturtiums attract, however. They are also a favorite of pollinators like bees, butterflies, and hummingbirds, and their pretty fragrance makes them a good choice for cut-flower gardens, too.
Nasturtiums are grown as annual plants in most areas, though they may perennialize in frost-free zones.
Types of Nasturtiums
There are many varieties of nasturtiums, which are divided into two main types: trailing or climbing types (Tropaeolum majus) and bush types (T. minus). As their names suggest, the main difference between them is their growth habit, with trailing nasturtiums forming long vines and bush nasturtiums remaining more compact. (Bush types are also sometimes called “dwarf” nasturtiums.)
Trailing nasturtiums are a great choice for growing in a window box or hanging basket, as their vines will drape and climb beautifully. Bush nasturtiums are a better choice for smaller gardens where space is limited.
Edible Flowers
An important feature of all nasturtiums is their edibility! Nasturtiums’ leaves, flowers, and seedpods have a peppery, almost mustard-like taste, which makes them lovely as a garnish in salads. The seedpods may also be pickled and used like capers.

Nasturtium Hardiness Zones
Your hardiness zones for nasturtiums is incorrect. The hardiness zones are not 10-11; they are 2-11. Big difference.
Hardiness Zones
The hardiness zones listed on this page indicate where the plant is capable of surviving winter. Nasturtiums can be grown in zones 2-11, but are typically only hardy in 10 and 11.
This page—- nasturtiums
I love how this page is laid out. It has all the valuable information about Nasturtiums. Is there a book with this same information, all of it, on other specific plants?
This literally ALL the helpful info on this plant and I’d love to see more of this.
nasturtiums
I found 4 seeds in the bottom of a packet so planted them. They have gone mad. Trailing 6feet and more. I have hung them on some string stretched across a fence. They are looking very healthy. Are they winter hardy? we have had a couple of frosts and that doesn't seem to have bothered them. If I just leave them, will they be OK or should I try to pot them up and over winter them in the greenhouse?
Seedling Nasturtium in December?
Hi The Editor,
I live in zone 10. Some of my Nasturtium from last year reseeded themselves and have grown plants back in my yard now in December. I just purchased some more seeds. Can I start seedlings now or need to wait until Spring? Thank you.

Can u cut the big leaves off nasturtiums
If I did this would I see more of the flowers
nasturtium leaves
The leaves are the way the plant gets its food to grow so don’t cut the leaves too early. However, if your nasturtium is getting out of control, then it’s best to trim back the tips and undersides of nasturtiums every few days even if it means trimming off flowers that have yet to bloom. This is hard to do but will keep the plant more compact and healthier. If you have too many leaves at expense of blooms, it may be because you are using fertilizer. It’s better to not fertilize them to have plants with good blooms that last longer rather than a crazy, full knockout plant that will only last a few weeks.
Nasturtiums
Aren't nasturtiums vines? My plants are not climbing on the trellis in the pot. Not sure why.

It depends upon the type of nasturtiums you are growing. The dwarf varieties grow low to the ground and stay in more of a bunched fashion, growing upwards (Jewel/Alaska varieties) . The trailing type (Tropaeolum majus (Empress/Moonlight/Amazon Jewell varieties)) will either cascade or can be trained to crawl upward onto a fence, border or stand. I hope this helps in some way?
Big beautiful blooming ‘bush’ of nasturtiums
Turned yellow and died in a small garden bed....after Spring. No California sun.
Why? Should I remove from garden bed?
Nasturtiums
If they’ve died completely, they can be removed from the bed. As for what caused them to perish, it’s hard to say without knowing more… What have the weather conditions been like? Dry? Wet? Are other plants growing well in the same soil?

planting nasturtium in zone 8
My nasturtiums are not growing. Small leaves, no flowers. They are in sandy soil.
Nasturtium not flowering
Can i use mono potassium phosphate to force my nasturtiums to force for blooming . As by mistake I have put fertiliser to nasturtiums
mono potassium phosphate
This is an eco-friendly fertilizer and your plants should benefit from it, if applied as directed on the package.
Nasturtium
Nasturtium grows fast in my small pot. Sunny climate in India. Temperature is rising now. Average 12-14 degrees C. Put water in afternoon.( 4-5 p.m).

Sounds like ideal conditions are in your favor!
Nasturtium
I have seen germination of Nasturtium seeds . It will grow in my flower pot. It's December. I cherish to see saplings now. Hope to give flowers in due time.
Nasturtiums
I buy packets of nasturtium seed showing a variety of colours but only ever get orange and yellow flowers. What is the cause of this?
Nasturtium leaves
Our nasturtiums bloom profusely, but the leaves are large and taller than the flowers. The leaves cover up almost all of the flowers. We would have to cut off the leaves to see the blooms. Is this because our soil is too rich or has too much nitrogen? Thanks in advance !

nasturtiums flowers lost in leaves
Shade reduces the number of blossoms and increases leaf size (and reach). It may also be due to too-moist soil.
Nasturtiums in the Fall
It is the end of September, do I need to pull my plants out or do I just leave them alone for next year? Will they die back over the winter?
nasturtiums in fall
Nasturtiums are annuals. They will die with the first frost—and not comeback.

eating Nasturtium
please tell me how are these Nasturtium able to be eating by humans ? how would one prepare them?
Eating nasturtium
They have a slight peppery taste. I wash and use fresh to add colour and flavour to salads and smoothies. I have also used in stir fries
Eating nasturtium
Take a stick of butter and let it soften to room temperature. Chop orange or red nasturtium flowers into small pieces and mix into the butter. Reform into any shape and refrigerate. The nasturtium butter will have a peppery flavor and will be a colorful addition to the lunch or dinner table. Use on toast or in any dish where pepper would compliment the taste and color would enhance the presentation. Also, simply chop nasturtium leaves and add into any salad. Like the flowers, the leaves add a peppery flavor. Add flowers and/or leaves in meat,vegetable, fruit or cheese dishes where pepper and color would be appreciated. Add just before serving to look brighter and taste fresher.
Can nasturtiums be planted in a hanging basket
Hi,
I'm from Islamabad...Pakistan. Our spring is almost here with no danger of any more frost.
I had these nasturtium seedlings....alĺ in one small pot...which were quite leggy and had yellow leaves. I planted these in a hanging basket(wire basket with coco liner) along with petunias and verbebas. Nasturtiums are inserted through the side slits. But now Im worried if they are going to catch back with petunias, which are quite healthy, or not...as the nasturtiums look very weak n shabby. The soil is a mix of peatmoss n perlite.
Shall I remove the nasturtiums or they'll do fine in the basket? Please advise.
Thanks
