This genus of the Rosaceae family contains around 200 species. Most are spiny large shrubs or small trees. The leaves are alternate, simple or lobed, some toothed, and deep green in color. The small white to pink flowers have 5 speals and/or petals depending on the species, and are carried in flat-topped clusters or are solitary. They are followed by nutlets, the fleshy covering of which is edible. The color of the fruits can be black, yellow, or bluish green, but the majority are bright red. Crataegus laevigata and C. monogyna have been used as hedging plants for centuries. These trees are commonly known as hawthorns.
CULTIVATION
Grow in sun or partial shade in any soil. Cultivars may be budded in summer or grafted in winter. Sow seeds as soon as ripe in a position protected from winter frosts. Germination may take up to 18 months. Some hawthorns are prone to fireblight.
Top Tip
Prune Crataegus branches to get rid of excessive twiggy growth, and trim hawthorn hedges in authumn or after flowering. Many specie have long sharp thorns, so take special care when pruning.
