Delphinium consolida QIS® White | Larkspur

Delphinium consolida QIS® White, commonly known as larkspur, is a timeless and elegant annual, cherished for its tall spikes of pure white, finely detailed flowers. This open-pollinated variety from the QIS® series is known for its uniform growth, strong stems, and superior performance in both fresh and dried flower arrangements.

Larkspur thrives in cooler conditions, making it a “cool flower” staple for early spring and autumn sowing. Whether you’re a cut flower grower, florist, or home gardener, QIS® White delivers stunning results and long-lasting beauty.
