Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Carya californica Common Name: California walnut Family: Juglandaceae Author: S.Wats. Known Hazards: None known Mature Height: 9 Mature Width: Habitat: Not known
Cultivation Notes: Prefers a deep moisture-retentive loam in a sunny sheltered position, requiring a good summer for best development[1, 63, 137, 200]. Slow growing[200].
This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c[200].
Plants are strongly tap-rooted and should be planted in their permanent positions as soon as possible[1, 137]. Sowing in situ would be the best method so long as the seed could be protected from mice[1, 200].
Trees are late coming into leaf (usually late May to June) and lose their leaves early in the autumn (usually in October)[137]. During this time they cast a heavy shade. These factors combine to make the trees eminently suitable for a mixed woodland planting with shrubs and other trees beneath them[137].
Plants in this genus are notably resistant to honey fungus[200].
Most species in this genus have quite a wide range of distribution and, in order to find trees more suited to this country, seed from the most appropriate provenances should be sought[137]. Most trees growing in Britain at present tend to only produce good seed after hot summers[137].
This species is closely related to J. hindsii.
Trees are self-fertile but larger crops of better quality seeds are produced if cross-pollination takes place[229].
