Signs of spring are showing at Crabtree Fields: blossom on a plum tree, near the Colville Place gate.

Plum (Prunus cerasifera) is one of the earliest trees to blossom in the park. It is native to southeast Europe and western Asia. It was introduced to Britain so long ago that it has become naturalised in the UK. Non-native species such as this are known as archeophytes; species introduced after 1492 are known as neophytes.

In Camden, the council keeps a database of trees where you can look up the tree if it is growing in the street, in a public park or on council owned land. Below is the entry for the plum at Crabtree Fields.
