Bunches of white petalled flowers or blossom appear, March – April before the leaves, making it stand out, from the other native hedgerow shrubs like the Hawthorn. The blossom attracts Butterflies, Bees and many other early spring insects.

The fruit of the Blackthorn is the sloe, it is similar to a small Black- Purple plum or Damson, with a blue powdery bloom. Sloes are often used to make jams and preserves, best picked after the first frost, said to sweeten and soften the fruit.
