Lark Spur - Consolida ajacis. A tall, showy annual with true blue flowers and light stalks. Its name is derived from its calyx which looks like a pointed spur from a side view. The plant looks very similar to the perennial Delphinium. However, that species is a perennial. Larkspurs have more delicate leaves; the flowers are smaller and aren't as densely packed on the stem. It self-seeds readily and grows to a height of 1-3 feet in the partial or full sun. Although blue is a favorite hue, this plant also has pink, red, purple, and white cultivars. The leaves and stems are a blue-green, and it blooms in spring and summer. Lark Spur takes care of itself, and the seeds so easily. The plants thrive best in well-drained soil that gets consistent water but doesn't remain wet. Blooms won't be profuse if there is too much shade, and in dry conditions, the plant may grow very little. If grown in full sun, most plants will be robust and not require staking, though others may grow spindly if the light is in short supply. Seedlings should be set about 10-12 inches apart to allow for ample room for the roots.
The Lark Spur, also commonly referred to by its Latin, scientific name Delphinium (meaning Dolphin), is a genus of flowering plants that are typically native to the Northern Continents. Lark Spur plants may also, more rarely, be found growing in mountainous regions of Africa. Larkspurs are distinct in that they are incredibly toxic, both to man and animal (don't eat them!) and can usually be identified by their five spreading and peculiarly shaped and extremely colorful, petals which look very similar to a fish or dolphin (hence the terminology). In color and hue, Larkspurs tend towards purple or bluish purple and grow in thick, tall tufts. Though they cannot be eaten raw by humans, Lark Spur is exceedingly attractive to butterflies and can be used in flowering gardens to attract them.
