Cultivation details

Landscape Uses:Espalier, Specimen. A very tolerant and easily grown plant, it succeeds in almost any soil or situation[1] so long as it is not water-logged[11]. It grows well in heavy clay soils and in poor shallow limestone soils[245]. Succeeds in cold exposed situations and tolerates industrial pollution[200]. This species is closely related to L. anagyroides[11]. There are some named varieties, selected for their ornamental value[11]. The flowers have a delicious vanilla scent[245]. Plants can be successfully transplanted even when quite large[200]. 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[200]. This species is notably susceptible to honey fungus[200]. Special Features:Not North American native, All or parts of this plant are poisonous, Blooms are very showy.

Propagation

Seed - best sown as soon as it is ripe in a greenhouse or cold frame[200]. Germination is usually very quick and good[78]. Prick out indoor-sown seedlings into individual pots when they are large enough to handle and plant them out in the summer. Another option is to pre-soak the stored seed for 12 hours in warm water and sow in an outdoor seed bed in early spring. These plants an be allowed to grow on in the seedbed for two years before planting them out in the winter. Cuttings of mature wood in late winter planted in the open ground[200].
