Sophora microphylla

Very small leaves (microphylla) and a tangled juvenile form, tending to straighten up and grow from an upright trunk at about four years. Kōwhai are suited to upper bank plantings of riparian areas. They also make beautiful shade or specimen trees. Semi-deciduous. Hardy. In spring the tree is covered with beautiful bright yellow flowers. Very attractive to birds. Will grow in sun or semi-shade in any resonable conditions.
