Beach plum is hardy to Zone 3. The plant is salt-tolerant. It prefers the full sun and well-drained soil. It spreads roots by putting out suckers. In dunes it is often partly buried in drifting sand.
Beach plum is grown for its fruit to a small extent. A project is in progress on the commercial cultivation of this fruit at Cornell University. But still there does not seem to be much scope for growing as an orchard fruit. However it is suitable for growing as a specimen plant or as patio plant for the flowering effect.
New trees are raised by softwood cuttings.
A few varieties of beach plum is also available. One has yellow fruits and is mostly available in Cape Cod area. Others like Estham, Hancock and Squibnocket are superior selections having larger and better flavoured fruits.
