Fall Mums (Chrysanthemum)

Chrysanthemums are a diverse genus of flowering plants in the daisy family, grown as garden perennials, cut flowers, and seasonal potted displays. Species and cultivars vary in form, flower shape, season, and hardiness, so match care and winter expectations to the particular plant.

The RHS describes hardy garden chrysanthemums flowering from September to November and notes that flowers vary in shape and color.

Newly planted chrysanthemums need regular water through active growth; keep soil or compost from drying completely, while avoiding waterlogged conditions. Container and florist forms may have different light, timing, and winter needs from hardy border cultivars. ## Seasonal care Hardy garden chrysanthemums die back in winter and regrow in spring, though frost protection can still be useful. Pinching young garden plants in early summer encourages branching and a fuller display. Avoid applying garden perennial assumptions to a pot mum without checking its specific growing guidance.

Pinch garden forms early in the season when a bushier habit is desired, remove faded flowers to keep displays tidy, and mulch in-ground plants before winter. Protect container plants from hard frost and follow cultivar-specific advice for overwintering.
