Delphinium belladonna Bellamosum

8 Plugs Shipped in a Mini Greenhouse

Planting Guide:

Fall - plant approximately 6 weeks before your first hard freeze date.

Delphinium belladonna Bellamosum is generally suitable for fall planting in USDA zones 5 and higher (unprotected), and zone 4 and lower with additional protection from a greenhouse, hoop house or frost cloth. This is strictly a guideline and we cannot guarantee winter survivability. 

Early Spring (cold soil) - plant approximately 2 weeks before your last frost date.

Delphinium 'Bellamosum' features rich cobalt-blue blooms on airy, branching stems, offering a looser, more natural habit than traditional upright delphinium types. As a Belladonna variety, it produces elegant spires that are well-suited to both cutting and garden use, with excellent vase life and a more relaxed structure that blends easily into informal arrangements. Best planted in spring in cooler climates or fall in warmer zones, 'Bellamosum' thrives in full sun and well-drained soil, preferring milder temperatures for optimal stem length and bloom quality. Ideal for northern gardeners or anyone seeking true blue tones without the rigid form of taller hybrids, this delphinium brings refined color and movement to borders and bouquets alike.
