About O'Henry
O'Henry is California's premium late-season peach — massive, firm, and intensely flavored with yellow flesh and a deep red blush. It's the choice of farmers' market growers.
O'Henry requires 750 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
Large fruit size requires aggressive thinning; susceptible to split pits in irregular watering.
❌ Common Misconception
Can I grow O'Henry in Zone 10 or warmer?
No. While O'Henry is listed for zones 5-9, it requires 750 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.
