TREES & Plants

Yellowwood

A medium-sized tree, 30 to 40 feet high,  with smooth bark, large hanging clusters of fragrant white flowers, and clear yellow fall color. Choose a yellowwood tree for excellent shade in a small to medium-sized landscape.   Another useful quality of the yellowwood is its deep roots, which allow for other plants to be grown easily underneath its branches.

Tree & Plant Care

Should be planted in the spring only.
Use corrective pruning to eliminate weak branch forks when young but do not prune in late winter and early spring due to excessive bleeding.
Roots of the yellowwood grow deep which allows for other plants to be grown easily underneath the tree.   
Tolerant of high pH soils.

Disease, pests, and problems

Can develop splitting at the crotch of the tree.
Susceptible to verticillium wilt and borer damage.

Native geographic location and habitat

Native to scattered areas in some southern states.

Bark color and texture 

Smooth gray to brown. Interior wood is yellow.

Leaf or needle arrangement, size, shape, and texture

Alternate, oddly-pinnate compound leaves, 8 to 12 inches long;  leaflets 2 to 3 inches long, ovate, with entire margins;  bright green in summer, turning clear yellow in fall.

Flower arrangement, shape, and size

Drooping clusters (panicles) of white pea-type flowers.
Clusters are 8 to14 inches long and resemble white wisteria.
