Cherry Plum (Prunus cerasifera)


CHERRY PLUM (Prunus cerasifera)
Family: Rosaceae

The Cherry plum (or Myrobalan) is a native of the Balkans, Russia, Central Asia and the Middle East (Zohary et al. 2012: 140-141). Here in Britain it is introduced and the trees are largely relicts of earlier plantings or self-sown, feral forms. It is confined almost entirely to the Midlands and SE England where the small trees can dominate overgrown hedgerows (for distribution maps see Online Atlas of the British and Irish Flora). The trees have spines that although often long are relatively thin. Normally it is the earliest plum to flower. Its showy flowers (with leaves) open around mid March (Lang 1987) and the fruits ripen from late June right through into early August, with occasional yellow-fruited trees producing fruit into late Sepember[i]. The fruits are pendulous and hang singly on relatively long pedicels of about 15 mm. Like cherries, the fruits are rounded and often a rich cherry red, though they can range from deep purple to custard-yellow. However, with a diameter of 15-30 mm they are a lot larger than wild cherries (Prunus avium; for examples of the range of fruit morphologies see Botu et al. 2012; Faust 2011: figure 1).

They have been described as ‘melting, very juicy’, and with ‘a pleasant, lively, subacid flavour’ (Downing 1857; see entry in Plants For A Future [PFAF] database). The flavour of some of the mature fruits can be overly sweet and insipid, although the flavour does sharpen somewhat when the fruits are boiled (Hillman unpublished field notes). This is probably because boiling releases some of the acids initially concentrated in the skin. On Turkey’s Anatolian Plateau, wild populations of what taxonomists have classified as the same species (albeit listed under its synonym: Prunus divaricata; Dönmez and Yildirmili 2000: 197-200) have red-flushed, yellow-skinned fruits that, eaten raw, are highly acidic [ii].

Prehistoric and historic usage
Cherry plums have been identified on Roman and Medieval sites in Europe (Bosi et al. 2009; van der Veen et al. 2008; Willcox 1977).
