About Tulameen
Tulameen produces the largest, most beautiful raspberries you'll ever see — long, conical berries with exceptional flavor and a glossy sheen that makes them farmers' market showstoppers. The benchmark for fresh-market quality.
Tulameen requires 800 chill hours — the number of hours between 32°F and 45°F during winter dormancy. Without enough chill, the tree may fail to flower properly or produce poor fruit.
Common Challenges
High chill requirement limits it to cold-winter regions; canes are susceptible to root rot in heavy soils; thorny.
Common Misconception
Can I grow Tulameen in Zone 10 or warmer?
No. While Tulameen is listed for zones 5-9, it requires 800 chill hours to produce fruit. Warm zones like 10+ typically receive only 200-400 chill hours. The tree may survive but will not fruit reliably. Consider low-chill alternatives like Anna apple (200h) or Tropic Snow peach (200h) instead.
