Hawthorns are ideal hedging plants, produce masses of flowers and display good autumn colours, says Dave Holland. Hawthorn is a familiar sight across the UK. These trees and shrubs are widely employed as hedging and are frequent colonisers of abandoned grasslands. Two species are British natives - the common hawthorn, or May tree, C. monogyna, and the Midland hawthorn, C. laevigata. Both will form small trees, although they are more frequently seen as large shrubs or multi-stems.
