Annual cycle
Bare branches through winter. Leaves emerge in spring, followed by profuse, fragrant white flower racemes in May and June. Pollinated flowers develop into hanging pods that persist into autumn. Leaves turn yellow before falling in autumn, leaving the spiny winter framework.
Safety note
The branches bear sharp stipular spines which can cause injury. Take care when handling or working near the tree.

Scientific profile
Robinia pseudoacacia is a deciduous tree with thick, deeply fissured bark. It typically reaches about 17 m in height. The leaves are alternate, imparipinnate, with 3–10 pairs of elliptical to ovate leaflets that are entire, obtuse or slightly notched at the tip, and nearly glabrous. A pair of stout stipular spines marks the leaf base. The fragrant, white pea-like flowers, each 15–20 mm long and with a yellowish blotch on the standard petal, appear in pendulous axillary racemes 10–20 cm long in May and June. The fruit is a compressed, glabrous, pendulous legume 5–10 cm by about 1 cm. The tree is a neophyte in Britain, where it is introduced and established. It grows in partial shade on moderately moist, nutrient-rich, neutral to slightly acid soils and shows little tolerance of saline conditions. It is deciduous, shedding its leaves in winter.
