I really enjoy this plant, as do the hummingbirds. It literally drips with nectar in the hotter weather. It is in bloom all during the summer and into the fall in my zone 6b garden. It dies back to the root during the winter and then in late spring sends up shoots. Very colorful and interesting addition to the garden. I mail ordered my first plant last year, but was very surprised to find one at a local nursery this year.

This forms a woody, somewhat sprawling shrub, in my Zone 9a garden in Bremerton, Washington. It needs some pruning to keep it in shape, and is now about 6 feet tall and with hundreds of inflorescences, flowering from June until at least November as long as old inflorescences are removed.

This is an easy and often overlooked plant, usefully giving colour in the late summer and autumn when many plants are past their best
