Taxus cuspidata Japanese yew Evergreen tree (1 Page of 5) The Taxus cuspidata plant species is found in E. Asia - Japan. It is a member of the Taxaceae family. Common gardeners may know the plant as Japanese yew. Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Taxus cuspidata Common Name: Japanese yew Family: Taxaceae Author: Sieb.&Zucc. Known Hazards: All parts of the plant, except the flesh of the fruit, are highly poisonous[1, 4, 7, 10, 19, 65]. Mature Height: 10 Mature Width: 10 Habitat: Mountains throughout Japan[58].
Propagation Notes: Seed - can be very slow to germinate, often taking 2 or more years[78, 80]. It is best sown as soon as it is ripe in the autumn when it should germinate 18 months later. Stored seed may take 2 years or more to germinate. 4 months warm followed by 4 months cold stratification may help reduce the germination time[113]. Harvesting the seed 'green' (when fully developed but before it has dried on the plant) and then sowing it immediately has not been found to reduce the germination time because the inhibiting factors develop too early[80]. Prick out the seedlings into individual pots once they are large enough to handle and grow them on in pots in a cold frame. The seedlings are very slow-growing and will probably require at least 2 years of pot cultivation before being large enough to plant out. Any planting out is best done in late spring or early summer, after the last expected frosts[K].
Cuttings of half-ripe terminal shoots, 5 - 8cm long, July/August in a shaded frame. Should root by late September but leave them in the frame over winter and plant out in late spring[78]. High percentage[11].
Cuttings of ripe terminal shoots, taken in winter after a hard frost, in a shaded frame[113].
