Identification and Reproduction


  • English hawthorn is a deciduous shrub or small tree in the Rosaceae family, native to Europe.
  • It grows up to ten metres tall, and is scaly and prickly.
  • It has broad, alternately arranged leaves. New shoots will appear reddish-brown.
  • Leaves are egg-shaped, three to seven lobes, and look like “paws”.
  • They have toothed edges, and are sometimes hairy.
  • Its flowers have pink to white petals, and grow in clusters similar to cherry blossoms.


  • It will produce berries after ten years, and these seeds can be spread by birds, animals, soil, and water.
  • Berries will stay on the tree over the winter.
  • This plant may also spread vegetatively.

Habitat & Ecology

  • English hawthorn becomes bushy and dense and will shade out native plants.
  • It prefers moist soil, such as woodlands, grasslands, and riparian areas.
  • It is drought-tolerant and somewhat shade-tolerant.


  • This plant can invade pastures.
  • It grows into thickets within forests, blocking animal movement and crowding out native plants.


  • Remove English hawthorn trees, or use chemical control on the trunks.
  • Trees can be dug out when they are saplings, but after maturing, the roots are too deep and thick.
  • Trees should not be dug out while bearing fruit.
