Perennial Chrysanthemums are essential for the grand finale floral display of the autumn garden, and if you have room for only one perennial Chrysanthemum, it should be ‘Sheffield’, (sometimes known as ‘Sheffield Pink’ or ‘Sheffield Apricot’). Single soft apricot-pink 3″ daisies appear in October and offer a late pollen source for bees and migrating butterflies. Stems can reach a willowy 3′, but you can have more compact plants (with more flower shoots) if you pinch back to 4-6″ in early July. Chrysanthemums are somewhat shallow rooted and spread by stolons. Plant in well drained soil, but irrigate when rainfall is limited.
