I have this planted in the most poorly drained spot on our generally poorly draining property and it survived an extremely wet winter gracefully :) I was concerned for it until I saw the buds late in the winter. And now, in April, its first bloom for us is far beyond what I expected. This little guy is covered with flowers. Great plant for poorly draining spots. Also, berries in June are very attractive to birds.
