About Cosmic Crisp
Cosmic Crisp is Washington State's billion-dollar apple — a Honeycrisp × Enterprise cross with exceptional crunch, balanced flavor, and remarkable storage life (up to 12 months). The starburst lenticels give it a 'cosmic' appearance.
Cosmic Crisp 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
Patented variety with limited availability; trees are expensive and may be restricted to licensed growers.
❌ Common Misconception
Can I grow Cosmic Crisp in Zone 9 or warmer?
No. While Cosmic Crisp is listed for zones 5-8, it requires 800 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.
