Cora,
Klein Lady, Angel's Honeymoon, Michele Obama and the yellow NOID are, and they came back from the roots this year, the rest are in pots. I had Fleming Island Rachel in the ground last year, but I dug her up, and she's in a pot this year.
They definitely do better planted in the ground, and have better, faster growth. I'll have to find permanent sites in the garden for the potted plants next year.
