planted in a mostly shaded location in a small bed raised a couple inches above the surroundings, with some sand added to loamy soil, and mulched with gravel; survived a cold and very snowy Denver winter, bloomed very nicely this spring

Very nice, loaded with blooms in mid to late spring. I grow in clay pot, in the winter I turn the pot on its side so that it will not get too wet. It does not like too much water. I fertilize it twice a year, once in spring and once in early fall with time released fertilizer. It has been in the same pot for four years, I may move it up one size this year, after flowers fade. It gets plantlets at the tip of the flower spikes, but I have never successfully transplanted any of them, I do keep trying.

These are really sweet little plants. It is critical not to overwater them at any time: excellent drainage is a must. Mulching the top of the soil with gravel or grit is very helpful -- it keeps the leaves from water in cold weather. Also important to avoid winter wet. An excellent plant for trough gardening.
