How to Grow
Sow these seeds indoors 4-6 weeks before the last expected frost. Plant at a depth of 1/4 inch, and make sure to keep seeds moist until germination. Seedlings can be transplanted outdoors after frost danger has passed. These seeds can also be sown directly outdoors anywhere from spring through fall, although they will bloom much later than if planted indoors. Plant after frost danger has passed. Delphinium plants are heavy feeders, so make sure to apply a balanced liquid fertilizer every month. Plants should be spaced approximately 30 inches apart for best performance.

The flowers are excellent for cutting. This flower seed produces Delphiniums that will grow at elevations up to 10,000 feet which is very rare.
