Now available: PLANTS FOR YOUR FOOD FOREST: an important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Cycas spp. - Various

Common Name Cycas, Sago Palm
Family Cycadaceae
USDA hardiness 8-12
Known Hazards The plants contain alkaloids of carcinogens and also an amino-acid that causes chronic nervous disorders[200]. Regular consumption of the plant leads to severe health problems and death. This toxic principle can be removed if the food is properly prepared but consumption of the plant still cannot be recommended because its use often means the death of the plant and it is becoming rare in the wild.
Habitats Species for sun and shade, desert, swamp, and rain forest [1-1].
Range Adapted throughout the tropics and subtropics.
Edibility Rating    (2 of 5)
Other Uses    (4 of 5)
Weed Potential No
Medicinal Rating    (2 of 5)

Other Uses

Carbon Farming Solutions - Industrial Crop: starch (Crops grown for non-food uses. Industrial crops provide resources in three main categories: materials, chemicals, and energy. Traditional materials include lumber and thatch, paper and cardboard, and textiles). Genera to investigate include: Cycas, Dioon, Encephalartos, Macrozamia, Microcycas, and Zamia [1-1]. Nearly all cycads fix low amounts of nitrogen. Ornamental - Landscape Uses: Border, Container, Massing, Seashore, Specimen.

Cultivation details

Hypothetical Crop  Industrial Crop: Starch  Management: Standard

Cycads (Division Cycadophyta) have adapted throughout the tropics and subtropics. Species for sun and shade, desert, swamp, and rain forest [1-1]. Climate: warm temperate to tropical. Humidity: arid to humid. Long lived but slow growing. Carbon Farming Solutions - Cultivation: hypothetical. Management: standard (Describes the non-destructive management systems that are used in cultivation) [1-1].

Carbon Farming

  • Hypothetical Crop  These are perennial plants that could potentially be developed for cultivation. Some, such as cycads (for industrial starch), as simply neglected; others, such as buckwheat and soybeans, are annual crops that could potentially be perennialised by crossing and relatives.
  • Industrial Crop: Starch  Materials and chemicals include bioplastics, paper, cardboard, solvents, paints, glues etc. Plants are usually pods, starchy fruits, nuts & seeds, starchy trunks.
  • Management: Standard  Plants grow to their standard height. Harvest fruit, seeds, or other products. Non-Destructive management systems.

Seed - best sown as soon as it is ripe, 2cm deep in individual pots which are then sealed in plastic bags to keep them moist until germination takes place. Germinates in 1 - 3 months at 25°c[164]. Pre-soak stored seed for 24 hours in warm water then treat as above. Division of suckers in the spring.
