Delphinium NEW MILLENNIUM , BLUE STARS MIX
A mixture of our best hybrid pink delphiniums which will range from light blue to deep purple
Bold spires of very dark bluish-purple flowers with white or brown bees stand up to 6' tall, adding a dramatic presence to the landscape in early summer. Approximately 10% of these flowers will be either white or pale mauve and are often double flowered. Removing spent flower spikes will result in another round of blooms on secondary spikes in late summer and fall. However, its large, coarsly textured leaves make this plant attractive even when it's not in bloom.
The English hybrid type of delphiniums are bred by New Zealand Delphiniums and are hand crossed to produce the highest quality seed. These F1 hybrids have excellent form, strong stems, and a vigorous growth habit. They were selected for their improved tolerance of heat and humidity, while retaining their cold hardiness.
Delphinium are a classic garden perennial. These plants are excellent for adding height to small spaces. Their tall flower spikes are easily recognizable when they come into flower in summer. When in flower, the spikes of these plants become heavy and should be staked to avoid toppling over in rough weather, especially taller varieties. Newer hybrids are longer lived than some of the more traditional cultivars.

How to grow:
DAYS TO GERMINATION:10-20 days at 65-70°F (18-21°C)
SOWING:Transplant (recommended) - Sow 10-16 weeks before last frost. Support strongly advised. Cover seed lightly. Transplant into larger cell packs or 3-4" containers 6-8 weeks after germination. Grow seedlings at 50-55°F (18-21°C) in the greenhouse or cold frames. Harden off and transplant outside after the last frost. Overhead irrigation is not advised. If growing in the greenhouse, transplant plugs into raised bed in August through September. Provide Hortonova (horizontal trellis) 12-18" above the beds. Keep temperatures below 60°F (16°C), in a heated structure. Feed with a balanced fertilizer. Direct seeding is not recommended.
Gardening Tips :
Delphiniums thrive in the cooler climates of the north country, though they will grow as far south as zone 7. The New Millenium hybrids, however, tend to be more tolerant of heat and humidity. They grow best in rich, well-drained soil with a basic pH. If your soil is naturally acidic, adding lime will help to provide these conditions. They are also heavy feeders. The addition of compost or manure to the soil as well the use of granular fertilizer will result in healthier, stronger plants.
Delphiniums can be grown in full sun or partial shade, though full sun may help to prevent powdery mildew. When planting, be sure to set the crown at or above soil level to avoid rot. Since their stems are hollow, taller varieties of Delphiniums should be staked to prevent damage from wind and rain. These new hybrids tend to be longer lived than their short-lived cousins but may be propagated from basal cuttings.
Culural Info :
Growing Temperature:
65-75° F days
50-55° F nights
Holding Temperature:
50-55° F
Soil PH:
5.8-6.2
EC (What is EC?):
1.5-2.0 pour through method
Fertility:
A balanced fertilizer using calcium and potassium nitrate is preferred. Once flower initiation occurs, use less nitrogen and more potassium and phosphorus.
Feed 75-100 ppm N at each watering.Vernalization: Not required.
Moisture:
Water well when first planted, then keep damp to moist, but not soggy, until initial bud breaks. Do not let the soil dry out completely. Avoid overhead watering to prevent diseases. Avoid overwatering and wet foliage after flower bud initiation occurs.
Planting Level:
Place crown at or just below soil surface.
PGRs/Pinching:
Apply Bonzi at 30 ppm or Sumagic at 5 ppm when flower stems begin to grow beyond the foliage.
Lighting:
For best results grow under photoperiods of 12 hours or longer.
Delphinium Pagan Purple Features: Attracts Butterfly and Hummingbirds, Cut Flower, Deer Resistant, Rabbit Resistant
Harvest: :1/4 to 1/3 of flowers on stem are open. Place immediately in water. Plants bloom again in late summer and early fall if cut back immediately after the first bloom.
