Landscape Attributes Willow Acacia is a multi-stemmed evergreen tree with a rounded form and gracefully weeping branches.

This is a relatively low maintenance tree, and should only be pruned after flowering to avoid removing any of the current season's flowers. It is a good choice for attracting birds to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. It has no significant negative characteristics.

It is very adaptable to both dry and moist growing conditions, but will not tolerate any standing water. It is considered to be drought-tolerant, and thus makes an ideal choice for xeriscaping or the moisture-conserving landscape.
