Deep violet flowers are produced from early to late summer on numerous heavily-branched spikes rather than one central stalk. Deadheading faded spikes by cutting them back to the main stem will encourage repeat blooming. The foliage of 'Bellamosum' is naturally compact and bushy, requiring minimal staking. This selection is breathtaking in fresh bouquets.

Delphiniums thrive in the cooler climates of the north country, though they will grow as far south as zone 7. They grow best in rich, well-drained soil with a basic pH. If your soil is naturally acidic, adding lime will help to provide these conditions. They are also heavy feeders. The addition of compost or manure to the soil as well the use of granular fertilizer will result in healthier, stronger plants.
Delphiniums can be grown in full sun or partial shade, though full sun may help to prevent powdery mildew. When planting, be sure to set the crown at or above soil level to avoid rot. These perennials tend to be short-lived and often start to lose their vigor after 2-3 years. Expect to replant them every few years or propagate new plants from basal cuttings of the original specimens.
