Sonata™ White Cosmos

Sonata™ White is a compact, upright Cosmos selection with pure white, daisy-shaped flowers and yellow centers above finely divided foliage. This annual blooms through the warm season and suits sunny borders, containers, and cutting gardens. ## Size and season Ball Seed lists the Sonata™ series at about 24 inches tall and 12–14 inches wide, with spring through late-summer flowering. The Royal Horticultural Society describes Sonata White as a compact annual with summer flowers, so allow for some variation by growing conditions. ## Siting and use Give plants a sunny position in moderately fertile, moist but well-drained soil. The upright stems and open flowers work in informal beds and as cut flowers; the cultivar’s compact habit also suits patio containers. The RHS includes the selection among plants for pollinating insects, and Ball Seed lists bees and butterflies among its characteristics. ## Maintenance Remove spent flower heads to encourage continued flowering.
