Flowers - Showy, blue, purple, or white, 1 1/2 to 2 in. broad, or about as broad as long; spurs stout and strongly incurved. General characteristics of plant resembling wild columbine. Preferred Habitat - Escaped from gardens to woods and fields in Eastern and Middle States. Native of Europe. Flowering Season - May-July. A heavier, less graceful flower than either the wild red and yellow columbine or the exquisite, long-spurred, blue and white species (A. coerulea) of the Rocky Mountain region; nevertheless this European immigrant, now making itself at home here, is a charming addition to our flora. How are insects to reach the well of nectar secreted in the tip of its incurved, hooked spur? Certain of the long-lipped bees, large bumblebees, whose tongues have developed as rapidly as the flower, are able to drain it. Hummingbirds, partial to red flowers, fertilize the wild columbine, but let this one alone. Muller watched a female bumblebee making several vain attempts to sip this blue one. Soon the brilliant idea of biting a hole through each spur flashed through her little brain, and the first experiment proving delightfully successful, she proceeded to bite holes through other flowers without first trying to suck them. Apparently she satisfied her feminine conscience with the reflection that the flower which made dining so difficult for its benefactors deserved no better treatment. FIELD or BRANCHED LARKSPUR; KNIGHT'S-SPUR; LARK-HEEL (Delphinium Consoilda) Crowfoot family Flowers - Blue to pinkish and whitish, 1 to 1 1/2 in. long, hung on slender stems and scattered along spreading branches; 5 petal-like sepals, the rear one prolonged into long, slender, curving spur; 2 petals, united. Stem: 1 to 2 1/2 ft. high. Leaves: Divided into very finely cut linear segments. Fruit: Erect, smooth pod tipped with a short beak; open on one side. Preferred Habitat - Roadsides and fields. Flowering Season - June-August. Distribution - Naturalized from Europe; from New Jersey southward, occasionally escaped from gardens farther north. Keats should certainly have extolled the larkspurs in his sonnet on blue. No more beautiful group of plants contributes to the charm of gardens, woods, and roadsides, where some have escaped cultivation and become naturalized, than the delphinium, that take their name from a fancied resemblance to a dolphin (delphin), given them by Linnaeus in one of his wild flights of imagination. Having lost the power to fertilize themselves, according to Muller, they are pollenized by both bees and butterflies, insects whose tongues have kept pace with the development of certain flowers, such as the larkspur, columbine, and violet, that they may reach into the deep recesses of the spurs where the nectar is hidden from all but benefactors.
