Torreya jackii Seeds | Jack Torreya

Jack torreya with long drooping sharp needles and green plum-like seeds on a slender tree — Jack Torreya (*Torreya jackii*): Taxaceae, a rare Chinese endemic yew relative of restricted mountain range.

LATIN NAME: Torreya jackii

COMMON NAME: Jack Torreya

Plant Profile

Jack torreya is a slender evergreen tree of the yew family, and it is one of the least-known conifers in cultivation outside China. It grows five to ten metres, sometimes to twelve, with a straight trunk, whorled branches and a narrow, rounded crown. The needles are its most distinctive feature: long, three to nine centimetres, stiff, sharply pointed and drooping, dark green above and marked with two broad white bands of stomata beneath.

The seed is a drupe-like structure, two to three centimetres long, green at first and turning purple-brown as the fleshy aril ripens, with a hard stone inside. Male and female cones are borne on separate trees, so a crop depends on both sexes being present. The species is native to a small area of Zhejiang, Fujian and Jiangxi in eastern China, where it grows in moist valleys and on shaded slopes, and it is nowhere common.

Science & Biotechnology

Torreya is one of the old lineages of the yew family, with a fossil record extending back through the Tertiary, and the living species are relics of a much wider distribution. Jack torreya was described from material collected in Zhejiang and is named for the collector rather than for any botanical feature. It is listed as endangered, with a fragmented range and low regeneration in the wild, largely because its seed is heavy, slow to disperse and heavily taken by animals.

The genus is worth separating carefully from its better-known relative. Torreya grandis, the Chinese torreya, is the species grown commercially for its roasted nuts, known as Fei Zi, and it is a different tree with shorter, less drooping needles and a much larger range. Jack torreya is not the nut crop, and its seed is not a commercial food; confusing the two in catalogues is common, and it matters for anyone expecting a crop.

Uses & Benefits

The species is grown by conifer collectors and in botanic gardens, where its long, drooping, sharp needles and its scarcity make it a plant of interest. It is slow and compact enough for a large rock garden or a woodland border, and it tolerates shade better than most conifers, which suits the understorey position it occupies in the wild. In a collection it is usually planted where the foliage can be seen at close range, since the habit is quiet rather than dramatic.

There is no timber or food use. Its value is conservation and horticulture, and the case for cultivating it is straightforward: a tree with a tiny wild range and poor regeneration is helped by ex-situ stock, and seed from cultivated trees is the only responsible source. Wild collection is illegal under Chinese protection and should not be considered.

Growing from Seed

The seed has a hard coat and an immature embryo, so it needs a long, two-stage treatment: three months warm at about twenty degrees, then three to five months cold at four degrees. Sow in a lime-free, humus-rich mix, cover lightly, and keep in shade. Germination is slow and can take a full year, and the seedlings are easily lost to damping off.

Grow the seedlings in deep pots in filtered shade for three years, keeping the compost moist but well drained. Plant out in autumn into cool, humus-rich, lime-free soil in half shade, and mulch every year with leaf mould. The tree is hardy once established but dislikes drying wind and summer drought, so a sheltered woodland position suits it best.

Our Take

A scarce, shade-tolerant yew relative with remarkable needles; a conservation plant more than a crop. Cool shade, lime-free soil and a long wait are the price of it.
