A newer selection of delphinium that produces tall, strong spires packed with cobalt blue florets and brightly contrasting central bees. The blue flowers pop to such an extent that they will draw your eye from a considerable distance and will add excellent vertical presence to any starting in early summer through fall. Use a single plant to create a focal point in your garden, or plant en masse for a remarkable display of color.
These Delphiniums were bred by New Zealand Delphiniums and are hand crossed to produce high quality seed. These plants are known as F1 hybrids. They have excellent form, strong stems, and display vigorous growth in the garden. They are hybridized for tolerance to heat and humidity, but still hardy to cold conditions.
Delphinium are a classic flower - they are often featured in artwork and a staple of the classic English cottage style garden. These plants thrive when used to add color and vertical height to a small space. The flower buds are easily recognizable as they shoot upward as spikes during the start of the bloom season. Once they bloom, delphinium draws the eye due to their appealing texture and color. If planted in an exposed area with windy conditions we recommend staking the flower stalks for protection. Even though this cultivar has strong stems the weight of the flowers can cause breakage in windy conditions.

Delphinium Cobalt Dreams
Delphinium thrive in cooler climates, although they will grow as far south as zone 7. If planted in areas that feature stretches of hot dry weather (Like us in southern Indiana!) plant them in soil rich in organic matter at a site that avoids the hottest afternoon sun. Keeping them well mulched will make a world of difference and is often the determining factor in success or failure. Use a slow release fertilizer and consider a top dressing of compost each year with mulch for best results. Powdery mildew can be a problem in the shadiest spots so having exposure to morning sun and good air circulation is the best way to prevent it.
