A shrub or tree, naturalised in hedges, wood-borders, scrub and waste places. Lowland.
This species has been grown in gardens since at least 995 (Harvey, 1981) and known from the wild since 1777. Three subspecies, subsp. domestica (plum), subsp. insititia (bullace) and subsp. italica (greengage) are often recognised. Many plants are relics of cultivation, but subsp. domestica is still being introduced from discarded plum stones. Although its overall range is similar to that in the 1962 Atlas, it is much better recorded.
Apparently derived from hybrids of P. cerasifera and P. spinosa; such hybrids occur in the Caucasus but P. domestica has been much modified in cultivation.
