Although the dormant plant is very cold-hardy, the young growth in spring, even on mature plants, is frost-tender and so it is best to grow the plants in a position sheltered from the early morning sun[K]. The Japanese plum yew is a very slow growing tree with an excellent potential as a food crop in Britain. It generally has a large crop of fruit and seeds, these are often eaten in Japan. In addition, the seeds seem to be immune to the predations of squirrels, the seed on trees growing at Kew Botanical gardens being untouched even though virtually every other nut tree there has its crop destroyed[K]. There has been some confusion in the naming of this species. Some botanists have separated off C. drupacea as a separate species, though most nowadays include it as a subspecies of this plant as C. harringtonia drupacea. (Sieb.&Zucc.)Koidzumi., differing from the species in its shortly pedunculate male catkins. In cultivation it is often known as the variety 'Fastigiata'. Another subspecies, C. harringtonia nana. (Nakai.)Rehd. is a small spreading shrub to 2 metres, spreading by means of suckers. This form is said to have the best fruit of this genus, it is a very hardy plant, succeeding as far north as S. Sweden and Nova Scotia.Plants are dioecious, but female plants sometimes produce fruits and infertile seeds in the absence of any male plants. However, at least one male plant for every five females should be grown if you are growing the plants for fruit and seed. Plants have also been known to change sex. Male cones are produced in the axils of the previous year's leaves, whilst female cones are borne at the base of branchlets.
