Yes, I went for Variegatus as that's more prostrate and fits with the description of groundcover. SQ grows to be a substantial shrub and i don't find it gets as pink as that either, though granted it is tinted.
Yes, it does, that's right Lilith
These forms used to be classified as E radicans - because they root along the stems. They use this to creep up anything nearby. When SQ is mature she really fills out and can become quite a sturdy shrub, particularly if you keep the straggly bits trimmed as hc says :)
