Comments: This is a large native shrub to small deciduous tree that produces lavender spring flowers and rather large hanging fruit with three distinct capsules that open to release hard nuts in late autumn and winter. Seeds are poisonous. Provide full sunlight and well drained soils. This is an excellent plant for naturalistic settings. The sculptural form in winter can be a special feature. Autumn foliage color is also outstanding most years.
