I like this plant. It may be the longest blooming plant I've ever seen. I can't think of anything else that blooms so long. Anyone wanting to root cuttings can just stick them in water and they will root within a few weeks, very easily!
I've been using Diamond Frost in combination pots and hanging baskets for about four years. It is more dependable than bacopa which always dries up and dies before the end of summer. Diamond Frost has a lacy, foamy look and weaves its way through other plants in the basket. This year I found another version called "Blush," which has a slight pinkish cast and two-toned leaves. So far, so good with it, too. Thanks for the tip about cuttings. I had not tried that.
I have also had great success with 'Diamond Frost' Euphorbia in southern Kansas. It withstands the high temperatures in the summer with no wilting. This year I also tried the 'Breathless Blush' in 2 locations and it is doing equally well.
