Koa

Acacia koa

Koa (Acacia koa) is a landscape plant valued for its form and structure as much as its bloom. It reaches roughly 110 ft at maturity and blooms in spring. Match it to full sun to part shade and water on a normal schedule until it is established. One caveat: like any plant, its published range is a guideline, not a guarantee, for the specific microclimate of your yard. Given a spot that matches its light and water needs, it is a dependable, low-drama addition to the yard.
