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 (like a big deep sunken bottomless pot) 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.

And why is the plant's name "Dixter"? Because, no doubt, because it was found or developed at Great Dixter, the marvelous home, garden and sales nursery of Christopher Lloyd, the recently deceased (2006) horticulturist and author of numerous books about British gardens, including his. Christopher Lloyd was one of my heroes and his garden continues under the aegis of Fergus Garrett, Lloyd's head gardener. Go online and google for much more on Great Dixter by Christopher Lloyd.
