Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Crataegus macrosperma Common Name: Big-fruit hawthorn Family: Rosaceae Author: Ashe. Known Hazards: None known Mature Height: 8 Mature Width: 8 Habitat: Found in a variety of habitats, including thickets and open woods[204], woods and river banks in dry clay soils and rich moist soils along the margins of oak woodlands[82].
Cultivation Notes: A very easily grown plant, it prefers a well-drained moisture retentive loamy soil but is not at all fussy[11, 200]. Once established, it succeeds in excessively moist soils and also tolerates drought[200]. It grows well on a chalk soil and also in heavy clay soils[200]. A position in full sun is best when plants are being grown for their fruit, they also succeed in semi-shade though fruit yields and quality will be lower in such a position[11, 200]. Most members of this genus succeed in exposed positions, they also tolerate atmospheric pollution[200].
Hybridizes freely with other members of this genus[200].
This is a very variable species, more than 50 different names have been given to it[235]. It varies quite considerably in the size and quality of its fruit[82]. It is very closely related to, and possibly no more than a part of C. flabellata[204].
Seedling trees take from 5 - 8 years before they start bearing fruit, though grafted trees will often flower heavily in their third year[K].
The flowers have a foetid smell somewhat like decaying fish. This attracts midges which are the main means of fertilization. When freshly open, the flowers have more pleasant scent with balsamic undertones[245].
Seedlings should not be left in a seedbed for more than 2 years without being transplanted[11].
