Color
Heartwood ranges from pale pinkish orange to deep brownish red; freshly cut surfaces are typically vibrant reddish orange, darkening over time to reddish/purplish brown (lighter pieces may age to grayish brown); UV-inhibiting finishes can slow but not prevent color shift.
Working Characteristics
- Generally easy to work
- quartersawn or interlocked grain may cause tearout when planing
- turns and glues well
- large open pores typically require filling for a smooth finish
- seal heartwood before applying reactive oil-based finishes (e.g., polyurethane) to avoid curing issues.
