Delphinium brachycentrum
Propagation: Seed - sow March/April in a cold frame or May outdoors[1]. Keep moist and in a shady position until germination takes place[2]. The seed has a limited viability so it should be stored in a sealed container at about 3°c[3]. Temperatures above 15°c inhibit germination[2]. The seed usually germinates in 2 - 9 weeks at 15°c[2]. When they are large enough to handle, prick the seedlings out into individual pots and plant them out into their permanent positions in the summer.
Cuttings of basal shoots in April/May, taken before they become hollow at the base, and planted in a cold frame[1].
Division in spring[1] or early autumn[3].
Cultivation: Prefers a rich well-drained soil and dislikes water-logged soils[3]. Requires an open sunny position[4].
A very ornamental plant[5].
Hybridises in the wild with Delphinium glaucum to form the hybrid D. x nutans[6].
A greedy plant, inhibiting the growth of nearby plants especially legumes[7].
Range: North-western N. America to E. Asia.
Habitat: Well-drained tundra slopes from sea level to 1600 metres in the Yukon and Alaska[6].
Usage: A parasiticide is obtained from the leaves[8]. It is quite toxic and so is for external use only.
Soil: Can grow in light, medium, and heavy soils.
Drainage: Prefers well drained soil.
Flower Type: Hermaphrodite
Known Hazards: All parts of the plant are toxic[8]. The plant is most toxic when it is young[3].
