Delphinium Cultorum

Delphinium (Delphinium Cultorum Summer Skies) - For these lovely, impressive perennials, grow Delphinium seeds! Summer Skies is marked by immense, graceful, light to medium blue flower spikes with white 'bees'. If the flower seeds are sown in early spring, Summer Skies will bloom the first year putting on a mid-summer show of color. This hybrid is from the Delphinium Pacific Giants series and it can reach a height of 6 feet. These tall beauties create a wonderful back border for the perennial flower garden, or plant them in a mass in the center of an island garden.

Delphinium grow best in full sun; however, in hotter zones they may be planted in bright shade areas that still receive some direct sunlight during the day. They thrive in rich, deeply worked soil that drains well. Prefers cool, moist summer nights. Space plants approximately 30 inches apart for optimum performance. Grows well in zones 3 - 7, but in hotter zones you may need to treat as hardy annual. Delphinium Cultorum care includes applying a balanced liquid fertilizer every month as the plants are heavy feeders.

To get a jump start on the growing season, sow Delphinium seeds indoors 4 - 6 weeks before last frost. Use sterile starter mix in trays and cover flower seeds 1/8 - 1/4 inches.

Delphinium Cultorum

Delphinium (Delphinium Cultorum Astolat) - Start Delphinium seeds and grow this tall and stately flower in the sunny border. Astolat is from the Pacific Giant Hybrids, and it has blooms of pink shades with a contrasting black center often called a "bee". The flowering spikes are dramatic accents in perennial borders with a height of nearly 70 inches. Grow this impressive flower from flower seed and create a striking background in the summer flower garden! Hummingbirds and butterflies will not leave these flowers alone. Delphiniums make great cut flowers as well.

Delphiniums are perennial in cool summer climates, but grown as annuals or biennials, especially where summers are hot. Sow the flower seeds in early spring when frost season is completely over. Seedlings started in spring may not bloom until the next spring. For large flower spikes, give rich, well-drained soil and regular feeding. Stake tall plants and protect from strong winds.

To get a jump start on the growing season, sow Delphinium seeds indoors 4 - 6 weeks before last frost. Use sterile starter mix in trays and cover flower seeds 1/8 - 1/4 inches.

LATIN NAME

Delphinium Cultorum

Delphinium (Delphinium Cultorum Black Knight) - Black Knight is a large perennial from the Pacific Giant Hybrids. It may require staking while flowering especially in windy areas as this plant can grow up to 6 feet tall. It has tall spikes of flowers in a gorgeous shade of dark violet-blue with a black bee in the center. Sow Delphinium seeds to produce this gorgeous addition to the perennial flower garden. Hummingbirds and bees will visit often!

Grow the plants in full sun and in compost rich well drained soil. Delphinium care includes applying a balanced liquid fertilizer every month as the plants are heavy feeders. Plants should be replaced every 3 to 4 years as they will become woody and begin to decline with age. Cut plants back after initial flowering for a possible second showing in fall. 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.

To get a jump start on the growing season, sow Pacific Giants Delphinium seeds indoors 4 - 6 weeks before last frost. Use sterile starter mix in trays and cover flower seeds 1/8 - 1/4 inches.

LATIN NAME

Delphinium Cultorum

Delphinium (Delphinium Cultorum King Arthur) - Make a statement in the flower garden with a mass planting of these tall flowers grown from Pacific Giants Delphinium seeds. They will be the stars of the early summer perennial garden. King Arthur bears rich, deep royal-violet petals marked with a white "bee" at the center of each flower. The Pacific Giant Hybrids are the tallest and showiest of all Delphiniums, with spikes that can reach heights of 6 feet. They are a short-lived plant, and usually grown as an annual or a biennial, but will grow as a perennial in certain climates. These flowers are in a distinct class noted for their tall, stately appearance and true blue colored flowers, a hue that is relatively rare in the perennial world.

If the main flower stalk is removed just after flowering, the plant will likely produce secondary blooms in late summer or early fall. 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.

LATIN NAME

Delphinium Elatum

Delphinium (Delphinium Elatum Magic Fountains Cherry Blossoms White Bee) - Delphiniums are the stars of the early summer border. Plants form low mounds of deeply-cut green leaves with upright spikes of satiny flowers. This shorter variety only reaches up to 36 inches and should not require staking. It features lovely cherry blossoms with a white eye, or "bee". Removing faded spikes at the base will encourage repeat blooming in fall. In hot, humid summer regions, plants do not usually last more than 2 to 3 years. Plants are often attacked by mildew in mid summer; simply cut back hard to encourage fresh foliage.

Delphinium grow best in full sun; however, in hotter zones they may be planted in bright shade areas that still receive some direct sunlight during the day. They thrive in rich, deeply worked soil that drains well. Prefers cool, moist summer nights. Space plants approximately 24 inches apart for optimum performance. Grows well in zones 3 - 7, but in hotter zones you may need to treat as hardy annual. Delphinium care includes applying a balanced liquid fertilizer every month as the plants are heavy feeders.

To get a jump start on the growing season, sow Delphinium seeds indoors 4 - 6 weeks before last frost. Use sterile starter mix in trays and cover flower seeds 1/8 - 1/4 inches.
