Use in Garden

Grows to a rounded mound in a xeric area to 3 to 4 feet across, give it plenty of room. Paired with Engelman's daisy, it'll provide season long color contrast. Excellent for a white or silver moonlight garden.


Cut back in early spring to about a third it's size to keep it neat and compact. Can be trimmed back more severely if necessary.
