Delphiniums bring to mind the vision of tall spikes of blue flowers in the background of the English perennial border and old fashioned cottage garden. The modern delphinium is a result of hybridization of delphinium species from many parts of the world.
A member of the buttercup (Ranunculaceae) family, delphinium consists of around 250 species of annuals, biennials, and perennials. Delphinium comes from the Greek word for dolphin, a reference to the new flower bud's resemblance to the bottle-like nose of the dolphin.
In Tudor England some of the species grown were referred to as "larkspur" apparently because the nectar sepal looked somewhat akin to a lark's claw. The common name larkspur also applies to a similar looking but different plant called Consolida ajacis.
Delphinium flowers may be single or double. Blue is the most common color; however, red, pink, white, and violet flowered varieties, also are available. Many flowers have white or black centers known as "bees."
Flowers occur in regal spikes with numerous flowers on each spike. The spikes of most delphiniums make attractive, long-lasting cut flowers. The foliage is palmately lobed and is divided into 3 to 7 parts depending upon the location on the stem.
Mature plants can reach 6 to 9 feet tall, though dwarf varieties grow 3 to 4 feet tall. Placing the tall plants in the background of a perennial bed is one popular choice. Delphiniums can also be used as specimen plants or as a small grouping in the garden.
