Perennial Sweet Peas - Knowledgebase Question

Walworth, WI
Question by chwpkw

Are there any perennial sweet peas available? Is this a plant that will continually reseed itself and that's why I see them coming up year after year? Any help would be greatly appreciated. Does Burpee sell seedlings for garden plants? If not, do your seeds last from year to year? I have a small plot and really don't need to buy packets of seeds every year. Any alternatives? I would prefer to buy Burpee products since they are such a well established company with good products.

There is a perennial type of sweet pea called Lathyrus latifolius. The roots of this plant are perennia, sprouting new foliage every spring. It will also reseed and can become invasive if not controlled by removing the seed pods before they mature. Of course if you want it to spread, you can allow the pods to broadcast their seeds before cutting the foliage back in the autumn. Burpee's catalog has a number of transplants for sale. You can request a copy of the newest catalog by phoning toll-free (800) 888-1447, or visiting the website at Seeds of perennial plants are available through the catalog, as well. Perennials will last for several years, and many will self-sow or grow large enough to be divided every few years. Hope this information helps you plan your garden!
