Fun Facts
- 🌱 Coralburst produces double flowers, meaning each bloom has extra petals arranged in full rosette form, creating a more showy and long-lasting display compared to single-flowered crabapple varieties.
- 🌱 The name 'crabapple' comes from the Scandinavian word 'krab' or the Dutch word 'krabb,' though the trees are native to North America and Asia, and Malus species have been cultivated for millennia.
- 🌱 Crabapples are technically any apple fruit under 2 inches in diameter and are the wild ancestors of cultivated apples; they are highly disease-resistant compared to their larger commercial cousins.
