Cosmos ‘Sonata White’

$4.75

Cosmos bipinnatus

PRE-ORDER: Ships approximately mid-March 2026

Cosmos ‘Sonata White’ is a compact, floriferous selection of the classic garden cosmos, producing crisp white daisy-like flowers above finely cut, feathery foliage. Unlike taller heirloom types, the Sonata series remains shorter and sturdier, making it well suited to borders, containers, and smaller garden spaces.

Blooming freely from early summer until frost, ‘Sonata White’ offers continuous color with very little effort. The clean white petals surround bright golden centers, creating a fresh, uncomplicated presence in mixed plantings. Its airy texture softens stronger forms and pairs beautifully with zinnias, grasses, and late-season perennials.

Easy to grow and quick to flower, cosmos thrives in average soil and full sun. Overly rich conditions may reduce bloom and increase foliage. Deadheading encourages continued flowering, though some seed heads may be left to encourage light self-sowing in mild climates.

Seeds will collect in your Trug until you checkout.
