Swamp Milkweed yellowing :(
I purchased a swamp milkweed plant (Ice Ballet) a couple weeks ago and planted it in a sunny but wet area of my yard. I have some mean clay in the back that tends to retain water about 3-4 inches down. Ever since I planted it the leaves have started to yellow from the bottom up, picture attached (these fell off just by touching them).
It's been raining a lot in No. VA since the beginning of the week and the yellowing has quickened. Could it be getting... *too* much water? I have a bee balm and BES planted in front of it (a bit drier) that seem to be doing fine. Not sure if I should wait it out, or dig it up and put it somewhere else. Thoughts?
