When to Seed Delphinium

This annual flower should be transplanted or direct seeded into the garden once all danger of frost has passed. It germinates best in soil temperatures of around 55 degrees Fahrenheit. 

Where to Plant Delphinium

This flower will need full sun and will prefer loose, well-draining soil, however, it is not super picky about its growing conditions. This flower can grow one to two feet tall, so keep this in mind when choosing a location.

Growing Delphinium

Sow seeds ⅛ inch deep and six to eight inches apart. Once mature, thin to 24 to 36 inches apart. This is a pretty low-maintenance crop, but regularly deadheading will result in more flowers. Once established, this flower is quite drought tolerant.

Harvesting Delphinium

Delphiniums can be harvested for fresh or dried cut flowers or left to mature in the garden to benefit the many pollinator species it supports.
