The sloe or blackthorn is a large shrub, a British native form of wild plum, bearing numerous blue-black fruits. They're bitter to taste, but make the most marvellous liqueur when soaked over winter in gin! Commonly used as a hedging item, the spiny plants are quite spectacular in late winter when smothered in brilliant white blossom. Will grow happily in heavy, wet, clay soils. Height after 10 years approximately 3m (10'). Full growing instructions included. February onward
