This plant is very happy in a low water part of my yard, which gets full sun. I love its independence and lack of many needs! This plant also has a strong odor, which sets it apart from other yarrows. It will flop over if it gets too much water, fertilization, or attention.

To deadhead, remove faded blooms to lateral buds. When all flowering is completed, cut down to basal foliage. Deadheading can significantly prolong bloom in young plants, but older plants may not benefit as much. Basal foliage can be left to remain for part of the winter and cutback in spring.

I ordered this from High Country Gardens (GREAT) and was so pleasantly surprised. I have 5 of them that started out in 2inch pots and went in poor clay alkaline soil and were fantastic. The first season they were 3 feet tall. I prune them almost to about 8 inches in late winter and they keep coming back as a tough perrenial should.
They bloom prolificly and last all season, strong smell and remind me of some sages but the butterflys love them, they look great with Russian sage and Caryopteris Blue Mist Spirea. I think they are division propagated and mine LOVE gravel mulch.

This plant has not done well in heavy, wet, clay soil for me. It is supposedly invasive. I have seen it planted with rudbeckia, which it contrasts with beautifully because of the different shapes of leaves and flowers.
