Plum trees on NON-DWARFING rootstocks. The so-called European Plums we sell were introduced into Europe from Syria and Persia and are the product of long selection and development over the last 1000 years. Plums have pale greenish yellow flesh and rich sugary flavour, ripening in February. Generally two varieties are needed for cross pollination, although there are some that are self fertile. Esplaiering these shuold be done on a fan shape only.
