Where to look

It grows best in moist, well-drained soil in full sunlight. It grows naturally in scrub, copses and woodland, but is commonly used as a hedging plant.

Description

Blackthorn (Prunus spinosa) is a small tree native to the UK. They are often found in hedges and because they are so spikey they are good at stopping animals escaping from their fields. They can live up to a hundred years! In April, they stand out from other trees because of the masses of white, insect pollinated flowers. Their flowers are hermaphrodite (made up of both male and female parts) and once pollinated they produce blue-black fruit known as sloes. Sloes aren’t in fact berries, but are drupes, a fleshy fruit with thin skin and a central stone containing the seed, like a plum or a peach. The blackthorn depends on birds and mammals eating the sloes and spreading the seed through their poo!
