Spring Snow Crabapple
Malus 'Spring Snow'
Rosaceae · broadleaf deciduous tree · introduced
Last updated
Malus 'Spring Snow' (Rosaceae) is a deciduous ornamental crabapple cultivar selected for its fruitless or nearly fruitless habit, eliminating the litter problem common to crabapples. White flowers appear in profusion in spring on an upright, oval-shaped tree.
Spring Snow performs best in full sun on well-drained soil. Bloom begins around 155 GDD (base 50 F) with full bloom near 209 GDD, making it one of the earliest-blooming crabapple cultivars. Its clean, fruitless habit makes it particularly suited for street tree and patio plantings where fruit drop would be problematic.
