About

Crataegus monogyna, known as common hawthorn, may tree, whitethorn, one-seed hawthorn, or single-seeded hawthorn, is a species of flowering plant in the rose family, Rosaceae. It grows to about 10 metres (33 feet) tall, producing hermaphrodite flowers in late spring. The berry-like pomes (known as haws) contain a stone-encased seed.

The plant is native to Europe, but has been introduced in many other parts of the world. The pome flesh is of little culinary interest due to its dryness, but is used to make jellies. The young leaves and petals are also edible.

Where it grows

The common hawthorn is native to Europe, being found in Ireland and Britain. It is also found in northwestern Africa and Western Asia, and has become naturalised in the Pacific Northwest in North America.
