This cultivar was brought forth in 2005 by Proven Winners. It probably is really a hybrid of E. hypericifolia x E. graminea and it does not produce seed from most likely being a hybrid. In the tropics it is an evergreen perennial in Zones 10 to 11, but in colder zones it is used as an annual often in pots or as a bedding plant. its airy fine-texture foliage and tiny white flowers make it seem sort of like a short Baby's-breath. It is commonly sold at many conventional nurseries and garden centers in the US.

'Diamond Frost' has performed well for me in both sun and shade. In the sun, the plants stay in a tidier mound with denser blooms. In the shade, they grow larger and lacier but are still attractive, particularly when used as a filler around more substantial plants. The plant has grown well for me both in the ground and in containers. However, don't let the delicate look of the plant fool you when planting it in mixed containers. It is quite vigorous and can quickly overwhelm weaker growers. Plants are very drought tolerant, but they don't seem to mind regular watering either. Plants are extremely easy to overwinter inside in a cool but non-freezing area, such as a garage or basement. Keep them on the dry side and water lightly when needed. When they are placed back outside in the spring, you can give them a trim and some fertilizer and they will rebound quickly.
