Copenhagen Hawthorn

Crataegus intricata (kree-TEE-gus in-tree-KAY-tuh)

Family: Rosaceae Native Shrub (3-15 ft)

Crataegus , or Hawthorn, includes many different species and varieties found throughout North Carolina, from swamps and river bottoms of the east to the higher mountain ridges of the west. Crataegus intricata , or Entangled Hawthorn, is a small native hawthorn typically found in open or rocky woodlands, meadows or fields or man-made disturbed areas. The plant has long, straight thorns, bears white blossoms in the spring, and produces edible fruit in the fall. Well-drained soil is a must but it grows in a wide variety of soil types and tolerates highly alkaline soils well. Some Hawthorns are grown as ornamentals, but because C. intricata easily forms dense thickets, its thorns make it a good security plant. The plant tolerates drought, air pollution, and wind. However, it does not do well in salt air. The plant is not fussy and tolerates moist soils and tolerates drought and heavy clay soils. For best fruit production, site the plant in full sun; it will do well in semi-shade, but fruit yields are lower. It grows from seed, but does best if you plant directly from ripened fruit in the fall for germination next spring. Stored seed may need acid scarification or cold/hot stratification for 120 days. When grown from seed, the trees take from 5 to 8 years before bearing fruit. The flowers have a smell like decaying fish, which attracts midges for pollination. When freshly open, the flowers have a more pleasant scent. Diseases, Pests, and Other Plant Problems: No significant disease or pest issues.

Wildlife value
Native bees nectar at the flowers. Important nectar flower for insects; food plant of many moths including the eggar moth; haws provide winter fruit for songbirds. It is a larval host plant for Gray Hairstreak (Strymon melinus), Red-spotted Purple (Limenitis arthemis astyanax), and Viceroy (Limenitis archippus). Red-spotted Purple and Viceroy rarely use this host plant in North Carolina. Good nesting habitat with thorns providing protection from predators.
