Goose plum is a native tree that produces clusters of white flowers in spring before the leaves emerge, followed by small red or yellow plums in summer. It naturally forms thickets through root suckers and can grow quite large, reaching 20-40 feet tall and wide at maturity.

Growing Goose Plum

Grow Goose Plum in full sun and medium water. Mature plants reach 240 to 480 inches tall and spread 180 to 360 inches wide. Expect high maintenance to keep it looking intentional in a front yard.

In an HOA neighborhood

Goose Plum takes more care to keep looking intentional in a front yard. Maintenance level: high. Consider it for backyard or mid-zone beds rather than the street edge.

Works well in: backyard only.

  • Forms thickets through aggressive suckering
  • Can appear unkempt without regular maintenance
  • Fruit drop creates mess on walkways

Wildlife value

Host plant for tiger swallowtail, spring azure.

The spring flowers attract bees and beetles for pollination. The fruits provide food for birds and small mammals, while the dense branching structure offers nesting sites.
