Landscape habit, uses: borders either massed, small groups or single; cut flowers

Other interest: of hybrid origin; famous breeder Luther Burbank in early part of this century bred original cultivars which were much as we see today, with breeding near the white peaks of Mt. Shasta in California hence the name; originally in genus Chrysanthemum and still listed there by some

Other culture: keep old flowers removed for repeat bloom; provide good air circulation to minimize disease

Propagation: seeds (21,000-35,000 seeds per ounce) is primary method even for cultivars; division of clumps every couple years or of rooted stoloniferous shoots
