Points of Interest

  • Has showy, white flowers that resemble wisteria blooms.  Flowers are highly fragrant and the display is highly prized by gardeners during the summer bloom.

  • Flowers do not appear until the plant is at least 10 years old and vary in terms of number of blooms on 2 to 5 year cycles.

  • A high number of bees are attracted to the flowers.

  • The name “yellowwood” comes from the color of the heartwood of the tree.  This yellow wood has been used to make dyes in the past.

  • Shallow roots allow it to tolerate wet soils. Deeper roots allow it to deal with droughts once the plant is well established.
