I made a little sweet pea bed this spring. It is a little too dry and they have struggled, but I'm still hoping for flowers. The seeds were ordered from two different companies, and one package definitely had smaller seeds. I started them early as I did the garden peas. The smaller seeds had fern like foliage, and the flowers opened a couple days ago. Last week a visiting friend told me that she thought it wasn't a sweet pea at all, but an invasive plant in the pea family called Vetch. Some reading shows that it is used as a green manure crop, but also highly invasive. I think that they may be right that it is Vetch. I'm attaching some photos if anyone is familiar with the plant? My plan is to remove it, but I'm unsure of disposal, of if I will have to dig it out. I don't want to damage my beloved sweet peas. I'm not sure how it spreads, or if I could let it flower and then remove it. I'm still exploring that. I called the seed company to tell them that their "sweet pea" seeds were not sweet peas at all, but I have yet to have a reply. Is anyone familar with this plant?
