Gardeners' Notes:

A delightful plant. Has beautiful blooms, pretty foliage and lovely fall color. It self sows easily, hopping around, making itself at home in my beds. It's a bit pushy, and has killed some of my geranium 'Brookside.' It works very well with anemone 'Robustissima' due to consecutive bloom time, and their ability to stand up to one another. With other companions it is well worth the time to moniter and yank it out if it tries to take over. I also have the species. 'Alpenglow' has a much longer period of bloom. It usually is quite rabbit and deer resistant.

G. sanguineum 'Alpenglow' forms a 1-foot-tall mound. The dark green foliage turns deep red in the fall. 'Alpenglow' blooms heavily in early summer and sporadically until frost. The variety originated at 'Alpenglow Gardens' Nursery in British Columbia.

It is a vigorous and dense grower, filling an area nicely and quite quickly, keeping down weed. For me, it grows taller than the 12-14 inches stated in the catalog.
It has plenty of brigth rose-red blooms and fine dark green foliage. A very desirable plant.
