Beach plum (Prunus maritima) is not well-known in its limited range, but popular among those who do, both as food and in environmental restoration. Beach plum is a rare tree that favors sand dune habitats where it typically reaches 4 to 7 feet and spreads through suckers, making it ideal for coastal management. As expected, it is also salt tolerant and drought tolerant, requiring well-draining soils and full sun. When cultivated inland, it can more than double in size, making a valuable ornamental too. Beach plum is host to over 80 species of caterpillars, making it delicious and valuable for the ecosystem.
Reports state that Beach plum is bitter or sour, making it not the best to eat fresh for the less adventurous palet, but using it to make into jam or drinks is increasingly popular.
