Gardeners' Notes:

I tried these in partial shade/sun in a raised planter. Prepped the bed, amended the soil. They did ok the first season. They bloomed in the spring and again in the fall. Really pretty blooms. The second season, they became very sparse. I couldn't keep them watered enough. They only bloomed in the spring. This is my 3rd season. One died over the winter. I'm trying to rehab the other two with regular water and soil sulpher. It just gets too dry here for them without regular watering.
