Unfortunately, redbuds would not thrive in Gotham due to the lack if sun here, and I thiiink mountain laurel could drown, with all the rain we get here. Sad times to be little old me
Yeah, both are native to Texas where it's all sun all the time, though I think the native range for eastern redbuds are close enough to where you are so maayyybbeee??
I think you could also try hydrangeas bc of how much water they need.
Though, I know there are a bunch of other pretty flowering plants that prefer partial to full shade! However, I don't really know that many bc, again, all sun, all the time. I do know that my school will be growing out this field by my dorm where there's always a bunch of wildflowers, so I'll send you pictures of them!
