Delphinium Blue Bird Delphinium Cultorum is a popular, tall growing, short-lived perennial. Delphinium Blue Bird seeds can be planted directly outdoors in spring, summer, or fall, and as one of the Pacific Giant Hybrids, this Delphinium is a tall variety that can grow up to 6 feet tall. Delphinium Blue Bird blooms with elegant spikes of large, medium-blue flowers that rise from delicate mounds of textured, dark-green foliage. Delphinium blooms in early and mid-summer, but if the primary flower stalks are cut off right after flowering, Delphinium can have secondary blooms in fall. The hummingbirds and butterflies like to visit the blooming Delphinium.
Delphinium Blue Bird is a long time cottage garden favorite, and as all Delphiniums this particular variety is a superb border and background flower that looks fabulous in mass planting. If the Delphinium Cultorum seeds are started indoors or outdoors right after last frost, Delphinium may bloom the first year. Delphinium Blue Bird blooms best when it grows in full sun and rich, moist, well drained soil, and the tall, strong stems along with extremely showy flowers make Delphinium one of the most valuable cut flowers.
