This is an awesome small shrub with elongated leaves with white stripes. It covers itself in tiny white flowers in early spring. It's rounded, but not particularly formal. It's a little twiggy, but that matches fine with the thin leaves and allows the white flowers to turn the entire shrub into a powderpuff. So far, ours have required no trimming. A happy, easy-going standout in the mixed perennial border. We love this one so much, we had to get four more last fall.

Here we are 3 years later. This year I did tidy up our bushes just a smidge, particularly the oldest one in the photographs, which is now 4' x 4'. No problems with reverting branches. No diseases or pests. Still a winner!
