These upright growers are usually pruned into single-trunked trees, but can be shrubby if permitted to keep basal suckers and low branches. Green bark; bright green leaves divided into three leaflets (like clover leaves). Handsome during bloom in mid- to late spring, when yellow, sweet pea–shaped flowers appear in hanging clusters similar to those of wisteria.
Use as a specimen in a lawn or border, plant in groups in front of a neutral background, or space regularly in a long border of perennials, rhododendrons, or lilacs. Flexible branches make plants easy to espalier or train over an arch (or a series of arches).
