Yellow Siris
Scientific name: Albizia chinensis
Overview
Yellow Siris is a medium to large deciduous or semi-deciduous hardwood tree in the Fabaceae family, native across portions of South, Southeast, and East Asia. Albizia chinensis occurs in warm tropical and subtropical forests and has also been cultivated for shade, agroforestry, soil improvement, and other practical purposes.
The wood generally ranges from pale yellowish brown to medium brown, sometimes developing warmer golden or reddish-brown tones in mature heartwood. Sapwood is usually lighter and can be distinguishable from the central wood. Grain is typically straight to interlocked, while texture ranges from medium to moderately coarse.
Yellow Siris is not among the world’s major internationally traded hardwoods, but its timber has regional importance for furniture, general construction, interior woodworking, agricultural uses, boxes, and other utility applications. Its botanical relationship to Red Siris, White Siris, East Indian Walnut, and other Albizia species makes it particularly useful within a documented collection of Asian hardwoods.
Quick Facts
- Common Name: Yellow Siris
- Alternate Common Name(s): Chinese Albizia
- Scientific Name: Albizia chinensis
- Region: Asian Hardwoods
- Tree Size: Approximately 50–100 ft (15–30 m) tall, occasionally larger
- Average Dried Weight: Reliable standardized species-specific value not widely documented
- Janka Hardness: Reliable standardized species-specific value not widely documented
- Grain: Straight to interlocked
- Texture: Medium to moderately coarse
Identification Characteristics
Yellow Siris generally produces pale yellowish-brown, golden-brown, or medium-brown wood. Older heartwood can develop somewhat warmer brown or reddish tones, while the sapwood typically remains paler.
Grain is generally straight but may become interlocked or irregular. Quarter-sawn material with interlocked grain can potentially show subtle ribbon-like figure.
Key identification traits include:
- Pale yellowish-brown to medium-brown wood
- Occasional golden or reddish-brown tones
- Lighter-colored sapwood
- Moderate heartwood and sapwood contrast
- Straight to interlocked grain
- Medium to moderately coarse texture
- Occasional subtle figure
Working Properties
Yellow Siris can generally be worked with conventional woodworking equipment, although machining behavior can vary with density and grain orientation.
Straight-grained material should machine relatively cleanly with sharp tools. Interlocked sections require greater care because reversing fibers can produce tear-out during planing, routing, and other surfacing operations.
- Machines reasonably well
- Sharp cutting tools improve surface quality
- Interlocked grain can produce tear-out
- Suitable for carving
- Suitable for wood turning
- Sands to a smooth surface
- Accepts finishes reasonably well
Safety Note
Detailed toxicity information specifically associated with Yellow Siris wood dust is limited. As with other hardwoods, dust generated during sawing, routing, turning, and sanding may cause eye, skin, and respiratory irritation.
Appropriate dust collection, eye protection, and respiratory protection are recommended during woodworking operations.
Common Uses
Yellow Siris is primarily a regional Asian timber rather than a major internationally traded hardwood. Where suitable material is available, the wood is used for numerous woodworking and utility applications, including:
- Furniture
- General construction
- Interior woodworking
- Cabinet components
- Boxes and crates
- Agricultural implements
- Carving
- Wood turning
- Utility woodworking
- Wood collections
Sustainability & Notes
Yellow Siris has value beyond timber production. Like many members of the Fabaceae family, the tree can participate in nitrogen-fixing relationships and has been incorporated into agroforestry and land-management systems.
Its relatively rapid growth, spreading crown, and adaptability have contributed to its use as a shade and multipurpose tree in parts of tropical and subtropical Asia.
Sustainability depends on the source of individual material. Wood from responsibly managed forests, plantations, agroforestry systems, or documented salvage sources is preferable to material of uncertain origin.
Accurate botanical identification is also important because common names such as siris and albizia are applied to numerous related species throughout Asia.
Comparative Notes & Related Species
Red Siris – A related Asian Albizia producing generally darker reddish-brown heartwood and providing a useful color comparison with Yellow Siris.
White Siris – Another Asian member of the genus whose generally paler wood provides a useful comparison of coloration and timber characteristics within Albizia.
East Indian Walnut – A related Albizia producing attractive brown to reddish-brown timber and demonstrating the considerable variation found within the genus.

Collector Notes
Yellow Siris is particularly useful for collectors building a comprehensive series of Albizia woods. The genus contains species ranging from extremely lightweight plantation timbers to heavier and more decorative furniture woods.
Displaying Yellow Siris alongside Red Siris, White Siris, East Indian Walnut, Silk Tree, Kalkora Silk Tree, Moluccan Albizia, and Falcataria can demonstrate substantial variation in color, density, grain, geographic distribution, and commercial importance among related species.
Because common names frequently overlap within this group, collector specimens should retain the scientific name Albizia chinensis, geographic origin, acquisition information, and provenance whenever available.
