Gardeners' Notes:

This plant has been very slow growing for me, and in the first year produced very few new leaves and only one bloom. It is in a west location next to the house, and I give it a bit of compost every fall. It is mulched with bark mulch. Now that it has been in that spot for several years, it is well established and has produced many blooms each year. I have not propagated other plants from it. I plan to leave it there, giving it a bit of compost each fall and enjoying the lovely mauve colored blooms early each spring. I think I may give it a bit of all purpose fertilizer this year just to see what she does.
