Plant
Larkspur
Delphinium / Consolida
Also known as: Delphinium, Consolida
A common name applied to perennial *Delphinium* and annual *Consolida* species in the buttercup family (Ranunculaceae). The tall blue-purple-white flower spikes are foundational to English cottage gardens and Russian dacha gardens. The Greek name *Delphinium* (dolphin) reflects the flower bud's resemblance to a dolphin's nose. Like many Ranunculaceae, the entire plant is toxic — delphinine and related alkaloids cause cardiac arrest in sufficient doses, and the plant is a major cause of livestock poisoning in western North American rangelands.
Scientific
The name “larkspur” is loosely applied across two related genera:
- Delphinium — perennial larkspurs; ~365 species across temperate Northern Hemisphere; the principal cottage-garden tall larkspurs
- Consolida — annual larkspurs; ~40 species; some authors include these in Delphinium
The Greek name Delphinium (dolphin) describes the flower-bud’s shape — the curving extended nectar spur at the back of the bud was thought to resemble a dolphin’s nose.
All parts of Delphinium and Consolida are toxic, especially seeds and young plants. The active compounds — delphinine and related diterpene alkaloids — block neuromuscular acetylcholine receptors and produce cardiac arrhythmia at sufficient doses. Larkspur is one of the most economically significant causes of cattle poisoning on western US rangelands; ranchers have specific management protocols to keep cattle off larkspur during the toxic-bloom season.
Cultural
Cottage-garden cultivation is the species’ principal contemporary use. Tall delphinium spikes (1–2 m tall, blue-purple-white-pink flower clusters) are a staple of English Victorian-style gardens and continue to feature heavily in modern temperate-climate ornamental horticulture.
The flower is the July birth month flower in many Western flower-of-the-month traditions. Larkspurs appear extensively in Russian dacha-garden tradition and in pre-revolutionary Russian impressionist garden painting.
The species’ toxicity makes it inappropriate for cut-flower bouquets in households with young children or pets; this is not always observed and occasional poisoning incidents result.
