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 >>>

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

Agroforestry Uses: Alnus jorullensis is an early successional species that regenerates and colonizes on open disturbed ground where other forest types have been destroyed though natural processes, such as landslides, or as a result of anthropogenic activities. It is used extensively in reforestation on disturbed sites and is widely grown in plantations throughout MesoAmerica and South America as a timber and fuel wood species[338 ]. In agroforestry it is used in silvo-pastures to provide nitrogen for increasing forage availability and quality, to improve soil fertility, and it is grown in association with crops such as corn and beans, coffee and wild blackberries[338 ]. Other Uses: The wood and bark is rich in tannin, which is used to impart a red colour[331 , 338 ]. Woodland guides select this species for marking new trails through the mountain forests. The red marks of the bark cut by their machetes re as effective as red paint in marking the way[331 ]. The wood is rather light and soft but firm, straight-grained, rather fine-textured, easy to work, tough and strong, finishes smoothly, is not durable in contact with the ground[331 ]. It is used for the manufacture of boxes for transporting vegetables, shoe trees, matchsticks, post poles, broom handles, domestic implements, plywood cores and particle board. It is also locally harvested for firewood, and charcoal production[338 ]. Used for ornamental planting in warm temperate areas such as southern California. Good for hedging and screening.

Alnus jorullensis is a plant of tropical montane forests, where temperatures are cool, with abundant rainfall. They are also found in high-elevation, open, oak-pine and fir woodlands in Mexico[338 ]. Grows best in a sunny position, but is somewhat shade tolerant[310 ]. Prefers a heavy soil and a damp situation, but it succeeds in ordinary garden soil[11 ]. Grows well in heavy clay soils[11 ]. Tolerates very infertile sites[200 ]. The tree responds well to coppicing[303 ]. This species has a symbiotic relationship with certain soil micro-organisms, these form nodules on the roots of the plants and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[200 ]. Semi-deciduous in cool climates.
