Dalbergia retusa (Caviuna, Cocobolo, Cocobolo Prieto, Funeram, Granadillo, Jacarandáholz, Nambar, ñamba, Nicaraguan Rosewood, Palisander, Palissandro, Palo Negro, Pau Preto, Rosewood, Urauna) is a plant species in the genus Dalbergia. It is known to produce the wood called cocobolo. It is a fair-sized tree, reported to reach 20–25 m in height. This is probably the species contributing most of the wood in the trade. Because of the wood's great beauty and high value, the trees yielding this wood have been heavily exploited and are now rare outside national parks, reserves, and plantations.
A deciduous tree of about 20 m tall with cylindrical trunk that branches from low down, Dalbergia retusa or commonly known as Cocobolo is one of commonly exploited in the wild for its highly valued timber used for a wide range of items including knife and tool handles, musical instruments.Dalbergia retusa is a deciduous Tree growing to 20 m (65ft) by 20 m (65ft) at a slow rate.
It is hardy to zone (UK) 10. The flowers are pollinated by Insects.
It can fix Nitrogen.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It prefers moist soil.Other Uses: A unique property of the species is the secretion of compounds that act as potent bactericides, fungicides and algaecides. The heartwood is a very dark red, with faint streaks of black similar to rosewood (Dalbergia nigra); it is clearly demarcated from the thick band of nearly white sapwood. The texture is fine, the grain crossed, lustrous in colour with a faintly fragrant smell. The wood is hard, heavy, strong, tough, and durable in contact with the soil. It is rather difficult to work, but takes a good polish.
