The maackias are small or medium- sized trees or rarely shrubs with rather large pinnate foliage and upright dense panicles of small white flowers appearing in summer. They are hardy North and not particular as to the soil, but prefer a warm and sunny position to bloom well. Propagation is by seeds sown in spring or by root cuttings like cladrastis. | The maackias are small or medium- sized trees or rarely shrubs with rather large pinnate foliage and upright dense panicles of small white flowers appearing in summer.
