About this genus:
Delphinium is a large genus of about 300 species of perennial flowering plants in the buttercup family (Ranunculaceae) native throughout the Northern Hemisphere. Delphinium is taken from the the Greek word delphinion, derived from delphinos or delphis for "dolphin" thought to be so named because of the similarity of the opening flower. The common name dates back to Tudor England when some of the species grown were referred to as Larkspur and occasionally Lark's Heel (from Shakespeare), Lark's Claw, and Knight's Spur, apparently because the nectar sepal looked somewhat akin to a lark's claw.
The history of the cultivated Delphiniums is old. As early as 1778 Delphinium species were being sold. Other species were rapidly introduced and by the middle of the 19th century hybridisation was being carried on by a number of French growers, chief among whom was Victor Lemoine, originator of most of the first varieties of perennial garden Delphiniums.
Often though of as a traditional cottage garden plant, in reality Delphinium can brighten up any type of garden. This because when they flower through June, July, and August they can add a vertical presence in a range of colours. These plants still have a reputation for being difficult to grow despite being popular in gardens over hundreds of years. We have tried many many cultivars in our garden at Ballyrobert and have selected our best performers for sale.
Delphiniums prefer sun or part shade. The books will tell you to treat them with all sorts of kitchen remedies, fertilizer, mulch, prayers, and what not. Don't bother - we don't. The cultivars we sell should be fine almost anywhere as long as they are not waterlogged or in full shade. They shouldn't need staked either unless the weather makes them grow faster than usual.
Try them with Achillea, Geranium, Campanula, and Aconitum - or even in swathes with other Delphinium (they are native so have a nice wildflower look)
