About Rainier
Rainier is the premium yellow-red cherry with delicate sweetness and lower acidity than dark varieties. It commands the highest prices at farmers' markets but is notoriously difficult to grow.
Rainier requires 700 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
Birds devastate the crop (yellow color attracts them); extremely prone to rain cracking and brown rot.
Common Misconception
Can I grow Rainier in Zone 9 or warmer?
No. While Rainier is listed for zones 5-8, it requires 700 chill hours to produce fruit. Warm zones like 9+ 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.
