Torreya californica Cultivation | Propagation | General Uses Cultivation Notes: Succeeds in ordinary garden soil, tolerating some lime[1]. Undemanding as to the soil pH[200]. Dislikes wind exposure[200]. Requires a sheltered position and either high humidity or a moist riverside soil[200]. Tolerates woodland shade very well[200]. One report says that trees are only hardy in the milder parts of Britain[1], whilst another says that trees are hardy in Britain at least as far north as Edinburgh[200]. This species is the only member of the genus that is fully adapted to cool maritime sites. It can actually grow faster in such a position than it does in the wild[200]. Trees in general grow better in the wetter western part of Britain[81]. Usually slow growing, though trees occasionally increase by 60cm in a year[185]. The bruised leaves release a powerful resinous smell[245]. The fruits are also aromatic[245]. The seed takes two summers to mature[229]. Trees often crop well at Kew, but there were no seeds formed in 1994[K]. A tree in fairly deep shade at Kew was carrying a good crop of seeds in the summer of 1996[K]. Plants are usually dioecious, but isolated female plants have been known to bear fruit in the absence of a pollinating male[11]. Plants are sometimes monoecious with dioecious branches. Male and female plants must usually be grown if seed is required. For further Torreya californica gardening information |
