True item has a dwarfish tight habit with twisting etc. of many leaves. I seldom see it offered here. I think name is often misapplied to another form with larger, more normal growth and mostly normal (flattish) leaves. This is common, sold under other names as well. I have never determined which is correct, multiple variegated forms have been named and described.

I have a variegated form that was labeled elegantissima, but doesn't have twisted leaves. It is placed in a quite sheltered position where it doesn't get winter sun and is covered with snow for most of the winter. Branches that stick out of the snow bank do get a bit of winter burn. It has survived for about 6 years now, but it hasn't grown a huge amount.
