Cultivation Details
Balsamorhiza deltoidea is hardy to at least -25°c[1]. Requires a deep fertile well-drained loam in full sun[2, 1]. Plants strongly resent winter wet[2, 1]. Plants are intolerant of root disturbance and should be planted into their permanent positions whilst still small[2]. Hybridizes in the wild with Balsamorhiza careyana[3].
Propagation
Seed - sow early spring in a greenhouse and only just cover the seed. Germination usually takes place within 2 - 6 days at 18°c. Either sow the seed in individual pots or pot up the seedlings as soon as they are large enough to handle and plant them out into their permanent positions in the summer[2]. Division in spring. Very difficult since the plant strongly resents root disturbance[2]. It is probably best to take quite small divisions, or basal cuttings, without disturbing the main clump. Pot these up into individual pots and keep them in light shade in the greenhouse until they are growing away well. Plant them out in the summer if they have grown sufficiently, otherwise over-winter them in the greenhouse and plant out in late spring.
