Cultivation Details

HabitDeciduous Shrub
GrowthFast

Caragana fruticosa prefers a continental climate with its hot summers, cold winters and usually a clear movement from one season to another. The dormant plant can tolerate temperatures down to at least -30°c, but in more maritime climates it is often tempted to come into growth early and this new growth can easily be damaged by late spring frosts[2] Succeeds in most well-drained soils, preferring full sun and a light sandy dry or well-drained soil[3, 4, 2]. Tolerates very alkaline soils[5]. Does not require a rich soil[3, 4, 6], succeeding on marginal land[7]. Established plants are drought resistant[7]. A fast growing plant[8]. This species is closely related to Caagana arborescens, differing in the larger flowers, shorter seedpods and the stipules being scarcely thorny[4]. It can probably be used in all the ways Caragana arborescens is used and thus has excellent potential as a human food.[PFAF]. A good bee plant[9]. Plants in this genus are notably resistant to honey fungus[2]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[2].

Propagation

Seed - best sown as soon as it is ripe in a cold frame[2]. It usually germinates in 2 weeks[PFAF]. Stored seed should be pre-soaked for 24 hours in warm water then sown in a cold frame[10, 11, 2]. If the seed has not swollen then scarify it and re-soak for another 12 hours before sowing[12]. Germination usually takes place within 2 - 3 weeks at 20°c[12]. Good percentage[4]. As soon as they are large enough to handle, prick the seedlings out into individual pots and grow them on in a greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, 7 - 10cm with a heel, mid summer in a frame[11]. Layering in spring. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-20. <temperate.theferns.info/plant/Caragana+fruticosa>
