Bigfruit Hawthorn

Crataegus macrosperma (kree-TEE-gus mak-roh-SPERM-uh)

Family: Rosaceae Native Understory (15-40 ft)

Bigfruit Hawthorn, is a native large shrub or small tree found in mesic or subxeric hardwood forests, wooded slopes, rock outcrops, pastures, thickets, mountain balds and rocky summits in the Piedmont and mountains of North Carolina. The tree may vary in shape and size and fruit production depending on where it is growing, because hybridization occurs easily with other hawthorns. Despite the common name, the fruit is not exceptionally large. Like most Hawthorns, bigfruit hawthorn has long straight thorns, white flowers that bloom in spring. and edible fruits in fall. This tree prefers a well-drained, moisture-retentive loamy soil but is not at all fussy and will tolerate clay soils. It also tolerates drought and wind, but does not do well with salt air. Fruiting is best in full sun. It will grow in partial shade, but that will impact the quantity and quality of the fruit. When grown from seed, the trees take 5 to 8 years before they start bearing fruit; grafted trees will often flower heavily in their third year. The flowers have a smell like decaying fish that attracts midges, which are the main means of fertilization. When freshly open, the flowers have more pleasant scent. use in a pollinator or woodland garden or naturalized areas s a barrier or hedge. Diseases, Pests, and Other Plant Problems: No significant diseases or pests.

Wildlife value
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). Good nesting habitat with thorns providing protection from predators.

Edibility

The fruit can be eaten raw or cooked. The fruit varies in size and quality, some forms having a thin yellow flesh that is juicy and acid while others have a much thicker flesh that is rather mealy but with a good flavor. The fruit can be used in making pies, preserves, etc, and can also be dried for later use.

Uses (ethnobotany)

The leaves, berries, and flowers are used in medicines and herbals for cardiovascular health. The wood is strong, heavy, and hard but has little commercial value.
