Description

Cladrastis kentukea / Yellowwood

Planting Points: Known for spectacular, cascading white flower clusters in late spring to early summer; blooms heavily every 2–3 years, lighter in off-years. Smooth gray bark and elegant branching provide year‑round interest. Requires gentle handling at planting—roots are sensitive to disturbance; establish in final location carefully. Develops strong branch unions if trained early; avoid heavy pruning later in life. Responds well to deep, consistent watering during establishment. Avoid exposed windy sites—branches may be somewhat brittle. Low pest and disease pressure; generally trouble-free in landscapes. Long-lived and highly ornamental once established.

Siting This Tree: Excellent specimen tree for lawns, courtyards, and prominent landscape spaces. Works beautifully near patios, garden beds, and walkways, where spectacular flowers can be appreciated up close. Ideal for arboretum-style plantings, estate landscapes, or parks. Best for sheltered sites with good soil and consistent moisture. Avoid tight urban locations with compacted soils or restricted rooting areas.
