Teak

Tectona grandis

Tall deciduous tropical tree of the Indian subcontinent and Southeast Asia, reaching 40 m, with the most weather-, water- and termite-resistant common hardwood timber in the world. The classic boat-deck, marine joinery, and outdoor-furniture timber.

Hardiness ratings

Teak hardiness across the four zone systems
SystemRatingTemperature rangeHow to read it
USDA hardiness zone Zone 10–12 −1.1 °C to 15.6 °C Plant tolerates down to this zone
RHS hardiness rating H1c 5 °C to 10 °C Plant needs at least this level of cold tolerance
Canadian plant hardiness zone Zone 9 −1 °C and warmer Plant tolerates down to this zone
Australian (ANBG) zone Zone 5–7 5 °C and warmer Plant tolerates down to this zone

Growing notes

  • Heartwood — exceptionally durable, oily, dimensionally stable, and rot-resistant; the standard timber for boat decking, marine joinery, and high-end outdoor furniture
  • WARNING: Wild old-growth Burmese teak is the subject of major sustainability and conflict-finance concerns, with international restrictions tightening. Purchase only certified plantation-grown teak (FSC-certified Indian, Indonesian, or Central American plantations are widely available)
  • Tropical — needs warm humid frost-free conditions, with a defined dry season for best timber quality
  • Trees take 25–60 years to reach harvest size on plantation, longer in the wild
  • Not reliably hardy outdoors in Canada — Canadian zone values shown represent the system maximum and do not imply garden cultivation north of the warmest coastal pockets.
