Swamp Milkweed is now in bloom... sort of. The specimens behind the house that sit in about 75% shade are now in full bloom, while the blooms on those in front, in nearly full sun, have yet to turn red.

This could be because of the amount of sun each plant is getting, though it could also be because of the differences in drainage (the specimen in front is contained inside landscaping ties, while the one in the front sits on the top ofa slope), or the fact that the rear plant is contained near the pond and has a constant water source.
