Butterfly Pea

Also called Atlantic Pigeon Wings (sometimes pigeonwings as one word)  - Latin name Clitoria Mariana. When I noticed this flower this morning on our walk I thought I'd never seen one before. But then when I used my Seek app on it, it told me I had a photo of it from August 2020. The two year old photo though, looks like the flower was very much past its prime. Anyway - this isn't something there are a lot of out there, it seems. I'm going to have to look a bit closer to see if there's just the one plant or if there are any more.
