This plant would normally be grown in full sun conditions in a rock garden where it would form an essentially stemless, tight mat.

Lori yes that's right, I've moved them all outdoors! I don't think its just the sunlight, because I had them under growlights, but I think they like need the wind and other aspects of the outdoors!!

Yeah, just pointing out that the photo is not at all what this plant normally looks like. Growlights have nowhere near the intensity of sunlight , and are only good for short periods, e.g. for starting seeds. (High intensity lights, e.g. metal halide, etc. are much better but not real pleasant to be around. )
