Blackthorn (Prunus spinosa)

Blackthorn is in flower at the Shorefield. 

The bark is black with long, quite vicious spines and the small leaves are serrated and dull green in colour and measure from 2 to 4 cm in length. The leaves provide food for the larvae of Black and Brown Hairstreak butterflies. The tree is also the food plant for the caterpillars of the following moths - March, Common Emerald, Little Emerald, Mottle Pug, Feathered Thorn, Orange, Scalloped Hazel, Scalloped Oak, Swallowtailed, Brimstone, August Thorn, Early Thorn, Pale Brindled Beauty, Blue Bordered Carpet, Broken Barred Carpet, November, Pale November, Winter, Sloe Pug, Green Pug, Sharp Angled Peacock and The Magpie.
