My thug is the species - I think tougher than the named cultivars. And it looks just like Tarev's only big. They'll get 9 to 12 inches tall and just as wide and the leaves are hairy/scratchy. Be careful about the thugginess - they are very tough to dig up if you decide they're too thuggish. You can only pull the babies. After a year, it's a shovel. My unnamed variegated one doesn't throw off a lot of seedlings but I usually deadhead it. It will grow a "plain" section from time to time that I snip out.
