Delphinium (Delphinium Cultorum Blue Bird) - Easy-to-grow from Delphinium seed, Blue Bird is a Pacific Giant Hybrid grown as a perennial in some areas and as an annual in other areas. Its mid-blue flowers have white centers. The flowers are large but short-lived and bloom on tall stems that grow up to 6 feet in height. Grow Pacific Giants at the back of a border or in the middle of an island bed. Delphiniums provide a unique and colorful addition to any flower garden. They also attract hummingbirds and butterflies to the garden!
Grow Blue Bird in full sun and in fertile, well drained soil. Space new container grown plants 30 inches apart. Delphinium Cultorum care includes applying a balanced liquid fertilizer every month as the plants are heavy feeders. Also, because of this plant's potential height and hollow stems, plant in an area that is sheltered from high winds, or stake the plant to avoid them falling over or breaking.
To get a jump start on the growing season, sow Delphinium flower seeds indoors 4 - 6 weeks before last frost. Use sterile starter mix in trays and cover flower seeds 1/8 - 1/4 inches.

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.
