The RHS Hawthorn (Crataegus monogyna) is a fast growing, thorny native deciduous hedge, with dark glossy green leaves.
In spring, clusters of prominent scented white flowers burst into leaf within a few days of the initial buds appearing, followed by glossy red haws in autumn, which sustain out native birds. The leaves are 3,5 or 7 lobed, bright green tinged with red. Prune out old growth after flowering to encourage new stems that will bloom the following year, taking care not to remove flowering stems.
RHS Hawthorn makes an excellent hedge with a long season of interest. Trim between July and March. For hedges 3-20ft (0.9-6m), plant 9-12ins (23-30cm) apart or for a denser or stock-proof hedge, plant in a staggered double row with 15ins (38cm) between rows and 19ins (45cm) between plants.
Bare root hedging is a very low cost way of planting a hedge, but is only available to buy and plant when dormant (November-March). Orders ahead of 1st November will be stored to guarantee an early delivery date.
Hawthorn is suitable for all soil types and positions, in particular grows well in town, coastal or exposed gardens. It has no serious insect or disease problems. Potential diseases include leaf spot or fireblight. Potential insects include aphids, caterpillars or gall mites. Only birds will eat the bitter cherries.
Toxicity; the fruit can cause mild stomach upset if ingested.
