Plus, wild plum tree care is effortless since the trees actually thrive on neglect. The wild plum can be found in most cool to temperate states. It is often planted by birds who flock to the fruits when they are season. The multi-stemmed trees grow in thickets at abandoned sites and disturbed soil areas. Trees form suckers freely and will create a large colony over time. Trees can grow 15-25 feet ( 4.5-7.6 m.) tall. Pretty 5-petaled, white flowers form around March just before the leaves appear.
