Is anyone else trying either of these? The Scleranthus uniflorus is wonderful, so vividly green, looks like a moss although the label says it isn't a true moss. It looks like a more compact and even shorter Irish Moss, and the label reads: "it is far more tolerant of drought and sun" [than Irish Moss]. It seems to blend into itself when planted in groups, very quickly. The question is how it will do over winter... so far it is very ornamental. Another groundcover which has done beautifully, remains tight and compact, is a soft green, with tiny leaves, faintly grey-green, and spreads [but less vigorously than Blue Star Creeper] is very very tiny and has tiny star-like yellow flowers on it at the moment -- and is one which I have not seen for sale in my area [Victoria and Saanich, BC] for the past two years, although during a wonderful 2006 multi-nursery offering of groundcovers here I was able to purchase and try it: Hypericum empetrifolium nanum, "St. John's Wort" [not the regularly seen St. John's Wort, for sure]... has anyone tried this one?
