Crataegus phaenopyrum (Washington Hawthorn)


Michael's Opinion

The Washington Hawthorn is a quite a beautiful specimen when in bloom. The fruit that persist throughout the winter gives added colour to the landscape. Thorns do take away from its beauty as the trees are not suited for high traffic areas. Overall it’s a very attractive tree due its compact size and showy fruit. A great addition to any garden.
