Adirondack White Flowering Crabapple

‘Adirondack’ is a deciduous flowering crabapple selected at the U.S. National Arboretum. Its red buds open to white flowers in spring, followed by small orange-red fruit that can remain into winter. The cultivar has a narrow, upright crown and is noted for resistance to several common crabapple diseases. [The Morton Arboretum’s crabapple guide](https://mortonarb.org/plant-and-protect/trees-and-plants/crabapple-cultivars/) and [The Dawes Arboretum’s Adirondack profile](https://dawesarb.arboretumexplorer.org/taxon-24423.aspx) describe its flowers, fruit, form, and landscape uses. ## Landscape Use Use it as a specimen tree or in a group where spring flowers and persistent fruit bring seasonal interest. Its upright habit can suit a narrower planting space than a broad, spreading crabapple. Published mature dimensions vary: Morton gives 12–18 feet high and 6–10 feet wide, while Dawes reports about 20 feet by 12 feet; allow room for a mature crown. ## Maintenance Plant in full sun in moist, well-drained soil; crabapples tolerate many soil types and prefer slightly acidic ground. Prune lightly in late winter or just after flowering to improve structure, and remove dead, diseased, or crossing branches. Check periodically for suckers at the base and remove them near ground level.
