Edible portion, Seeds, Leaves, Shoots. The young tips are cooked and eaten. They are boiled. 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. The leaves and seeds are used in the treatment of eye problems such as ophthalmia[ , ]. The bark is astringent[ ] It is taken internally to treat diarrhoea, dysentery and piles[ ].

The bark is used externally to treat boils[ ]. The flowers are applied locally to maturate boils and alleviate skin eruptions[ ]. The powdered seeds are used to treat scrofula[ ]. Saponin from the pods and roots has spermicidal activity[ ].

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. Agroforestry Uses: A fast-growing tree that fixes atmospheric nitrogen and succeeds in full sun, it is an excellent plant to use as a pioneer when establishing woodland or woodland gardens, though its ability to invade areas outside its native range means that it is best used only within its native area[ K ].

Due to its extensive, fairly shallow root system, the tree is a good soil binder and is recommended for eroded lands and erosion control, for example along river embankments[ , ]. The nitrogen-rich leaves are valuable as mulch and green manure[ , ]. Free-standing trees appear to enhance pasture production and quality beneath the canopy due to the increased nitrogen status of the soil[ ]. In an open woodland environment it has been repeatedly observed that there is modification of the ground cover with enhancement of grass production and quality beneath the canopy[ ].

Seedlings and cuttings are used as an initial shade in coffee, cardamom, cocoa plantations etc[ , , ]. The tree is also used in rehabilitating old cocoa farms or on improved fallows intended for cocoa cultivation due to its nitrogen-fixing abilities[ ].

Although not completely wind firm, the tree is tolerant of salt-laden winds and can be planted in moderately exposed coastal situations and as quick-growing shelter for less hardy plants[ , ].

A valued honey tree because of its production of both nectar and pollen[ ]. Other Uses It seems probable that the fruits can yield 10 barrels of ethanol per hectare per year[ ].

The trunk yields a reddish gum that is used as an adulterant of gum arabic[ ]. A red dye is obtained from the bark[ ]. It can cause skin irritation[ ]. When dried and pounded, the bark can be used for soap[ , ]. The heartwood is golden brown when freshly cut, turning to a rich dark brown with black streaks; it is clearly demarcated from the paler sapwood. The texture is medium to coarse; the grain deeply interlocked; lustre is medium; there is no distinctive odour or taste The wood is moderately heavy and hard; strong and fairly durable.

It seasons well, works and polishes easily. An excellent, very decorative timber, it has been compared to black walnut. The wood is suitable for turnery, carving, general construction, furniture, veneer, agricultural implements etc[ , , , , ].

More generally the wood is useful for fuel wood because of its high productivity[ , ]. It makes an excellent charcoal[ , ]. Plants can succeed at elevations from sea level to 1, metres in areas where annual daytime temperatures are within the range 26 - 36c, but can tolerate 12 - 48c[ , ]. It prefers a mean annual rainfall in the range - 2,mm, but tolerates - 2,mm[ , ]. Seedlings will not tolerate frost, but trees are moderately frost resistant when established[ ].

Prefers a well-drained, moisture-retentive soil and a position in full sun[ ]. Plants are able to succeed in most soil types, including saline but excluding cracking clay, so long as they are well drained[ ]. Tolerant of degraded or nutritionally poor soils[ ]. Prefers a pH in the range 6 - 7, tolerating 5. Established plants are very drought tolerant[ ]. Seedlings will not tolerate waterlogging[ ]. Requires a position sheltered from strong winds[ ]. Widely cultivated, the tree has become established in the wild in various areas outside its native range and is considered to be invasive in some of these areas[ ].

A fast-growing species, it can reach a height of 18 metres within 10 years from seed[ ]. When grown as a fuel crop on a coppice rotation of 10 - 15 years, it can produce about 5 cubic metres per hectare[ ].

Optimum annual wood production is 15 - 20 cubic metres per hectare[ ]. Plants have brittle limbs that can break off in high winds[ ]. They also have a shallow, though wide-spreading root system that does not support them well in windy positions[ ]. The dried seedpods hanging on the tree constantly rattle in the wind[ ].

Reserves in the root system enable young plants to survive total defoliation from fire or grazing, but with an obvious setback in growth[ ]. The tree coppices well, responds to pollarding, pruning and lopping, and will produce root suckers if the roots are exposed[ ] The trees are killed by even light fires[ ].

This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots 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[ ].

The tree is not Rhizobium specific, and native strains are nearly always capable of producing an abundance of nodules[ ]. Their goal is to maintain healthy productive animals. They can be utilized all year, but are designed to bridge the forage scarcity of annual dry seasons.

Fodder bank plants are usually trees or shrubs, and often legumes. The relatively deep roots of these woody perennials allow them to reach soil nutrients and moisture not available to grasses and herbaceous plants. Non-destructive management systems maintaining the soil organic carbon.

Harvest fruit, seeds, or other products. Non-Destructive management systems. Examples include shea, carob, Brazil nuts and fibers such as ramie and sisal. Our new book to be released soon is Edible Shrubs. Shop Now Propagation Seed. The species is not particularly hard-seeded and requires only mild treatment e. Be careful, though, since some seeds are quite thin-skinned and can be damaged if the water is too hot[ ]. A proportion of the seeds germinate immediately without any treatment[ ].

Plants can be direct-sown, container grown, or raised in a massed seed-bed and planted out as bare-rooted stems[ ]. There is nothing published on preferred rhizobial strains but it appears to nodulate readily without inoculation[ ]. Semi-ripe cuttings. Air layering.

Many, see text Albizia lebbeck is a species of Albizia , native to Indomalaya , New Guinea and Northern Australia [1] [2] and widely cultivated and naturalised in other tropical and subtropical regions. The latter name is a play on the sound the seeds make as they rattle inside the pods. Being one of the most widespread and common species of Albizia worldwide, it is often simply called siris, though this name may refer to any locally common member of the genus. The leaves are bipinnate, 7.
