Gardeners' Notes:


On May 17, 2014, coriaceous from ROSLINDALE, MA wrote:

This is attractive enough to win over even some who don't usually like orange in the garden. Soft orange bracts surround the flowers. The stems are red, the foliage has red tints, especially in spring, and the red leaf midvein (fading to white) adds a nice touch.

This is not a clump-former---plants spread underground by rhizomes. Some may find them too aggressive for border use. I grew this for a year, which isn't long enough to judge. It did not self-sow for me. A root barrier might be prudent.

This species comes from the Himalayas and hates hot summers. Armitage says it doesn't perform well in eastern North America south of Z7.

All I can say is. This is a VERY nice looking plant!! And I don't favor any orange-like blooming plants. Long lived and have not found it to be invasive. Yes, it has spread over the last 6 years about 3 feet from where I originally planted it. And was planted in a bed with other shade plants. Just give it space..
