Relatively easy to grow, the main thing to remember is that sweet peas like cool weather, requiring about 50 days of temperatures under 60 degrees to bloom well. In cooler climates, sow seeds outdoors in early spring as soon as the soil is workable. Seedlings can withstand a touch of frost, so don't stress if the weather turns colder. Flowering will last from spring into summer, and even into fall in some regions. A thick layer of mulch will keep roots cool and extend the blooming as long as possible.

Another benefit of growing sweet peas is they make excellent, long-lasting cut flowers. A clutch of them in a small vase brings their heavenly scent and the romance of the cottage garden indoors. And by regularly cutting flowers from the plant, you'll be encouraging more blooms.
