Dear les; I'll add that this plant should be grown in full sun, but can tolerate slight shade. I also think good drainage is important although it can also tolerate some moisture especially in spring. I'd give mature height about 36-40 inches. And speaking of D. v. I have seen some plants with lots of silver streak marks in the foliage along the veins and other plants with little or no silver streaking. It seems small plants show this less than mature plants too. I'd sure like to get a heavily silver streaked form-anyone have a lead? Anyone know of a variegated D.v.? best jim W. James W.
