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.

Please note that Delphinium are toxic. We've planted them with no adverse effects to children, pets, livestock or wildlife. That said, it is important to note that they do have toxins and care should be taken when utilizing them in your garden.

General care for any tree or shrub is easy, but like any living thing will require your attention. Please educate yourself and follow these simple rules.

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.

Shallow root ball

I am looking forward to beautiful delphiniums. I am disappointed that the quart sized plants did not have deep roots so I believe it will take a bit longer for them to establish themselves in the garden. If the price is based on the expected maturity of the plant, these plants appeared to have only recently been sized up possibly from 5 in. containers. I hate to pay for empty soil and the associated shipping weight.

Nicely-packed plants and detailed planting instructions!

I had never ordered from New Blooms Nursery before, so when I received my seven delphiniums, each well-packed in its own cloth bag, I was pleasantly surprised. The accompanying instructions were very detailed, and, so far, I am following them to the letter with soil, mulch, and daily watering. As of today, all the plants, while still small, seem to be adjusting nicely to my garden.

Very happy with Cobalt Dreams!

It arrived timely and well packed - and instead of a plastic or coir pot, it had a felt one! Very clever! It's early days yet, but it has grown a bit, including some buds! I followed the directions - water, water, and more water. Looks like it's paying off!
