A friend gave me a start several years ago. While I was setting the plant down in the garden, a hummer came to the flowers. They love this plant. I'm in zone 9b. It spreads like crazy here by rhizomes. I try to keep it in bounds by burying edging and stones around the patch to help prevent it from spreading. I don't know if it's working.
The plant gets over 3' tall and I have to cut it back mid summer. It's super happy. Gets full sun.
