This is a gorgeous plant, the mahogany stems contrast beautifully with the dark green foliage, and the sprays of white flowers top it all off. Divides easily. Also purportedly gives one 'wild dreams' although I have not tried that.

I have failed with this plant twice. Once, it didn't make it through our zone 4b winter. Once it succombed to a mild dose of dog pee. Think its too delicate for my conditions!

My favorite Artemisia! Excellent foliage and very long lasting flowers in a creamy white. Reaches about 3 feet tall with the flowers. Easily divided by taking a section of the root-ball in late fall. Deciduous, but rebounds each spring with fresh new foliage.

I planted this 2003 summer, looked good and grew to 4 foot tall, buds on the stems and then one by one the stems wilted like they were drying up and now only two stems are left - i'm afraid soon those will be gone too - any ideas what happened?

Most Artemisias are grown for their foliage; this one has white flowers contrasting with dark green foliage and dark red-violet stems.
