Bought a small R. cautleoides from Brian Williams last fall and planted it out in the woods behind my house. Just a few days ago I saw it coming up, and that was after experiencing a winter with temps down to -3 or -4 and the ground being frozen solid for about a month and a half. Definitely hardy to zone 6b.

The plant I bought last year was a small seedling, but it already is almost as big as it was last fall when I planted it, so hopefully it will get even bigger this year.

Tuberous perennial from China.

Has upto 4 lance shaped, mid green leaves. Bears hooded, 2-3 lobed lipped flowers usually creamy yellow but can be white or purple.

Flowers June-September.

Likes a moist, well drained, humus rich soil in sheltered, cool, partial shade. Will not do well in warm gardens.

Hardy down to 7F and may be a little hardier if planted deeply.
