Title: Identification of a vine with purple flowers
Answered by: Nan Hampton
First of all, remember that one person's weed is another person's wildflower. If you like the vine and it isn't an invasive species, I see no reason why you shouldn't keep it and enjoy it. Now let's see if we can figure out what it might be.
If you do (as I did) a COMBINATION SEARCH in our Native Plant Database choosing 'New York' from Select State of Province, 'Vine' from Habit (general appearance) and 'Pink', 'Blue', 'Purple' and 'Violet' from Bloom Characteristics–Color, you will see 20 species of vines native to New York. Here are some from that search that sound a bit like your description:
Clitoria mariana (Atlantic pigeonwings)
Clematis occidentalis var. occidentalis (Purple clematis) and here are more photos.
Lathyrus japonicus (Beach pea) and here are photos and information.
Lathyrus palustris (Marsh pea)
Strophostyles helvola (Amberique-bean) and here are more photos and information.
Vicia americana (American vetch)
There is a good possibility that your plant is not a North American native. Here are a few non-native invasive vines that occur in New York that somewhat like your description. These are ones you would definitely want to remove.
Akebia quinata (chocolate vine)
Jacquemontia tamnifolia (smallflower morningglory)
Lathyrus latifolius (everlasting peavine)
Vicia cracca (bird vetch) and here are photos.
Vicia villosa (hairy vetch) and here are photos.
Vinca minor (common periwinkle)
It is also possible that your vine is non-native, but not considered invasive and I haven't shown it above. If none of the ones I've shown above is your vine, please visit our Plant Identification page to find links to plant identification forums that might be able to help you. All of the identification forum links allow you to submit photos for identification.
