I'm having difficulty finding a mature height for this, but then it probably depends which rootstock its on - so far seems to get about 3metres as a rough guide. this is actually a greengage type Plum tree, giving orangey green fruit. Plant in ordinary garden soil that doesn't get waterlogged, preferably in a sheltered spot out of the wind so the flowers don't get caught by frosts, keep well watered during dry spells for its first two years - needs a couple of gallons a water a week.
