With their seductive fragrance, sweet peas make great flowers for gardens and bouquets. These pea-like flowering annuals grow in many lovely colors and are suitable for a border, a woodland garden, and a trellis or arch. See how to plant and grow sweet peas. Early sowing is one of the secrets to sweet peas!
Cultivated sweet peas go back at least 300 years. In their native Sicily, these ornamental peas have weak stems and an intense orange-jasmine-honey scent. Modern hybrids are stronger-stalked and have larger blooms.
Growing sweet peas is akin to making a pie crust. Some people have the knack, others don’t. Sweet peas are quite hardy, growing from large, easy-to-handle, pea-like seeds. Still, they’re a bit tricky because they are slow to germinate. It’s worth experimenting with different seeds each year.

Sweetpeas
I live in San Diego, planted sweet peas in mid December. Plants are doing great but no flowers
Sweet peas can take 3 months
Sweet peas can take 3 months from planting to bloom. If your plants are healthy you should see blooms before long. You can feed them with a fertilizer that is high in phosphorous to promote more flowers.
Sweet Peas Zone 10
Hello, I am in San Diego too. I just sow the sweet pea seeds today in the small pot and I forgot soaking them. Do you think it's ok or I need to undo to soak them? Please help, thanks so much.
Am I too late?
I live in South Louisiana. Am I too late in planting my seeds, now?
Planting Sweet Peas
I’m afraid so. In your region, plant sweet peas in October or November and provide a good trellis. They’ll bloom in February or March and continue into May.
wintering..
I live in NE Ohio. My husband planted sweet peas earlier in the year. From what I am reading here, I think we probably planted them too late. They never bloomed, in fact, the didn't even grow very well until very late summer. It is now the end of November, we have had several hard frosts, and they are still green and bushy. My question is.... is there any chance that they will come up in the spring? As I said, they did not bloom, so it won't be a matter of them re-seeding, but could they grow back in the spring? If they could, should we leave them alone, or cut them back? Thanks for the information!!!
Sweet peas need to be
Sweet peas need to be protected from hard freezes and heavy snows. If the ground is still soft you can dig up the plants and plant them in a big container. Move the container into an unheated garage or shed and cover with some blankets if the outside temps. drop below 20 degrees. Do not prune the plants. Most people regard sweet peas as annuals and plant new seeds every year. The trick is to get the seeds growing early in the spring. You can start them indoors 6 to 8 weeks before your last spring frost and then get the seedlings outdoors as soon as possible.

my sweet peas went crazy ,
my sweet peas went crazy , beautiful and full of pods, can they be eaten?
Hi Elayne, No, the flower
Hi Elayne, No, the flower pods may look like they are edible but they are not! In fact, they are poisonous. Just enjoy the flowers. They make great cut flowers, too.
we were up in northern
we were up in northern California and picked cuttings of the wild sweet pea up there, ~ 2 wks+ ago. they have been sitting in a glass filled with water and some plant food in it. some of the cuttings still look healthy. i was wondering if i can get the cuttings to survive and root if put in healthy soil. we are in inland Ventura county of California.
can i dig in my sweet pea
can i dig in my sweet pea plants when they have finished producing, as i would my garden peas, to help replace nitrogen ? .I have searched everywhere for an answer to this question.
Hi Rose, Yes, you can chop
Hi Rose,
Yes, you can chop the sweet pea plants and turn the pieces into the soil, just like garden peas.
I live in the foothills of
I live in the foothills of Northern California and have some wild sweet peas growing. I would like to grow more vines so I can harvest the peas. They taste sooo good! Do the same growing tips apply (soaking the seeds, nicking them before planting)? When should I plant? Our summers are incredibly hot (it's been 105 for the last few days)and our winters are rainy and mostly in the high 30's low 40's at the coldest. Thank you so much for answers and such a great site!
eatting wild sweet pea pods
Mary, I wouldn't be eating any part of the wild sweet peas. I also live in the foothills, in Butte County and I has been told to me that they are very toxic to horses. I have been battling wild sweet peas that grow in a pasture. I would talk to the ag agent before eating any more.
I am trying to grow my sweet
I am trying to grow my sweet peas in pots on the balcony. I have the Old Spice variety and they are about a foot high right now. How long till they bloom? I think I planted them in early April and we are now in the first week of June. One of them looked like it had a small colored bud peeping out, but it has just remained as a mysterious little thing that has not unfurled for about 10 days now. What to do?

Ps so grateful i found this site been searching for days again ty in advance
Sweet peas love cool weather;
Sweet peas love cool weather; it might be getting too hot for them in Philly now. If you'd like to try, however, you can transplant them outside in part shade, in well-drained soil (not clay). They like sunshine, but they like cool soil. Organic mulch will help that, but certain mulches can also harbor slugs, especially the coarser materials such as bark mulch or straw. Fine organic matter isn't as attractive to slugs. You can also try planting your sweet peas in containers outdoors, using the potting soil etc. that you have. In the heat of the afternoon, provide some shade for them, or wheel them into a shady spot. In the fall, you might try planting more seeds outdoors--they should flower in spring, just when it's perfect weather for them.

I plant sweetpeas every
I plant sweetpeas every spring on the Victoria Day long weekend (live in Alberta Canada). I soul them in water for a day and plant about 150 seeds along my south exposure 8 meter fence with 2.5 meters high chicken wire. They take 2-3 weeks to come up and by August they reach the top of the chicken wire covering the whole fence. I water on a regular basis and clip the flowers for bouquets weekly. The fragrant aroma on a warm summer evening is great. Summer temperatures range from 9-20 degrees at night and 18-30 during day. Hope this helps.

I just planted sweet peas for the first time, I also live in Alberta. When can I expect them to flower? Thanks.
Hi wondering about the Sweet
Hi
wondering about the Sweet Peas, I live in St John's Nl, i have planted my sweet peas just about 2 weeks ago and they are about 4 inches high. If you let then die off in the fall, have you known then to seed again and survive the cold harsh winter.
I have a lava rock area on my
I have a lava rock area on my side yard with a nice sturdy fence that I would like to grow these on so I can create privacy from my neighbors as well as keep the flies away that gather from them not picking up their dog waste so this spot would be ideal, however i don't want to remove all the rock, will I still be able to grow this in the ground dispersed between the rocks? if not is there something else you can recommend that will climb up the fence and will tolerate the lava rock
thanks
Yes, sweet peas grow in lava
Yes, sweet peas grow in lava rock. Good choice! In fact, sweet peas thrive with poor soil and like to struggle. Don't baby them. Ignore them!
Due to topography, etc, I
Due to topography, etc, I have a cooler side to my home. I have an area herein which receives full sun, BUT, by about 1pm, it becomes shady. MUST the sweet pea (and/or the Morning Glory) have full sun ALL DAY?
I live in mid Georgia (zone
I live in mid Georgia (zone 8a) and planted some sweet peas in early March, according to the recommendations on the seed packet. The plants are growing great but haven't bloomed yet (early May). I am getting married in early September of next year and wonder when is the best time to plant next year in order to have flowers available for my wedding. By my calculations, it seems mid-May would be the right time to plant to produce September blooms, but I think Georgia will be too hot for them to grow properly at that time. Any suggestions? Is this even possible, or am I setting my hopes too high?
Hi Lara, Most sweet peas grow
Hi Lara,
Most sweet peas grow best in cooler regions but there are varieties available that tolerate heat and grow through the summer. 'Zinfandel', 'Cupani' and 'Painted Lady' are just a few. Read our planting and care information above. You can test a couple of different varieties this summer to see if you can keep them blooming until September. One trick to get them to bloom for a long period of time is to keep picking the flowers and not let them go to seed.
Dear almanac team. I live in
Dear almanac team. I live in Cape Town South Africa . My husband has been planting sweet pea seeds with no show of germination. Very frustrating for him ! We have put seeds into peat pots, planted in various places in the garden and if we are lucky, one out of 10 might germinate . Please help . We would love to have these beauties in our garden this winter and spring .

I have good luck with my sweet peas growing and climbing, what I need to know is what do I do with them in the spring. I have all the dead vines, do I cut them off, leave them or what?? I checked the other comments and unless I over looked it, I saw nothing on what to do with sweet peas in the spring??
Hi Carol, Sweet peas are
Hi Carol,
Sweet peas are usually grown as annuals. You sow the seeds in the spring and the plants will bloom and form seed pods during the summer. You can pick the seed pods when dry and save the seeds for the next year. In the fall pull the plants or cut off the dead vines.
