No harvest required for ornamental purposes. For wildlife or crafts, fruits naturally drop in fall and can be collected from ground. Fruits remain attractive on tree through winter; leave some for birds if desired. If harvesting flowers for arrangements, cut in early morning when buds are beginning to open.
Fun Facts

- 🌱 The magenta-red flowers appear before the leaves fully develop, creating a dramatic spring display that is visible from a distance.
- 🌱 Crabapples are the original ancestors of domestic apples, and many ornamental crabapples like Thunderchild can still produce edible (though tart) fruit suitable for preserves.
