artemesia versicolor

Although the entire plant of Artemesia versicolor is very attractive, I find the details most enchanting. This plant will spread with time, so it needs dividing every few years unless you want a dense mat with smaller leaves. You don't have to prune it to the ground every spring like I do, and instead of a uniform compact mound, the plant forms a lumpy spread of smaller leaves and the plant covers ground faster, rooting along the stems. In either case, you may want to prune off the flowers that form in mid-summer since the yellow puffs aren't very attractive and produce loads of air borne allergenic pollen.
