Delphinium
'Cobalt Dreams' Larkspur
This new selection produces strong, tall spires tightly packed with cobalt blue florets with brightly contrasting white central bees. They draw your attention from quite a distance and add terrific architectural presence to the garden in early summer and fall. Uniform color and form ensure a stunning display whether planted singly or en masse. 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.

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. May be propagated from basal cuttings.
