This is an erect evergreen shrub with thick stems which grow from the base to 12 feet tall with equal spread. The hairy leaves are deeply lobed. During the fall and winter, white chrysanthemum-like flowers bloom giving off a scent reminiscent of chocolate or freshly baked cookies. The flowers are followed by decorative, chartreuse seed heads. The genus name commemorates the eighteenth century Mexican politician and amateur botanist, Luis Montana and is one of the very few in the family Asteraceae that consists of trees and shrubs. Plant in full sun or semi-shade and water regularly. It is reported to be hardy at least to upper 20's F.
