Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Summary


Physical Characteristics

 icon of manicon of cone
Torreya grandis is an evergreen Tree growing to 25 m (82ft 0in) at a slow rate.
It is hardy to zone (UK) 8. It is in leaf all year, in flower in April, and the seeds ripen from October to November. The species is dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required). and is pollinated by Wind. The plant is not self-fertile.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in full shade (deep woodland) semi-shade (light woodland) or no shade. It prefers moist soil.

Seed - roasted[46, 61, 63, 105, 183, 266]. An edible oil is obtained from the seed[266].

Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.
Anthelmintic  Antitussive  Carminative  Laxative

The flowers are anthelmintic and carminative[218]. The seed is anthelmintic, antitussive, laxative and peptic[218].

Our new book Edible Shrubs is now available.

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

Other Uses

Essential  Oil  Wood

An essential oil is extracted from the aril (fruit)[266]. The wood is used in constructing buildings, bridges, and furniture[266].

Special Uses

Carbon Farming

Cultivation details

Management: Standard  Regional Crop  Staple Crop: Protein-oil

Succeeds in ordinary garden soil, tolerating some lime[1]. Requires a sheltered position and either high humidity or a moist riverside soil[200]. Dislikes wind exposure[200]. Tolerates woodland shade very well[200]. Requires hot, very humid summers for best growth[200]. This species is not very hardy in Britain, it only succeeds outdoors in the milder areas of the country[1]. It succeeds outdoors at Kew[11], a tree was 8 metres tall in 1970[185]. The seed takes two summers to mature[229]. The edible seed of this very ornamental evergreen tree is often sold in local markets in China. Closely related to T. nucifera[200]. Plants are dioecious so both male and female plants are required if seed is to be produced. Occasional trees are monoecious with dioecious branches.

Carbon Farming

  • Management: Standard  Plants grow to their standard height. Harvest fruit, seeds, or other products. Non-Destructive management systems.
  • Regional Crop  These crops have been domesticated and cultivated regionally but have not been adopted elsewhere and are typically not traded globally, Examples in this broad category include perennial cottons and many nuts and staple fruits.
  • Staple Crop: Protein-oil  (16+ percent protein, 16+ percent oil). Annuals include soybeans, peanuts, sunflower seeds. Perennials include seeds, beans, nuts, and fruits such as almond, Brazil nut, pistachio, walnut, hazel, and safou.

Propagation

Seed - best sown as soon as it is ripe in a cold frame. Some of the seed should germinate in the following spring though much of it might take another 12 months. Stored seed requires a period of cold stratification and can take 18 months or more to germinate. Prick out the seedlings into individual pots as soon as growth is observed and grow them on in light shade in the greenhouse for at least the next couple of winters, making sure to pot them on into larger pots as and when required. Plant them out into their permanent positions in early summer when the plants are at least 20cm tall. Cuttings of half-ripe shoots in late summer[1]. Cuttings do not grow well[11]. Layering.
