Spring Snow Crabapple

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.

‘Spring Snow’ is a problem-cultivar for maritime Puget Sound landscapes despite its appealing fruitless habit. The triploid sterility that eliminates fruit mess is a legitimate selling point — there is genuine demand for fruitless flowering trees near patios, swimming pools, sidewalks, and driveways. But the cultivar's high apple-scab susceptibility (MSU rates HS, with explicit "watch out" comment) is a serious regional liability. Maritime PNW spring weather — cool, wet, persistently humid — is exactly the condition apple scab requires, and Spring Snow defoliates noticeably in scab-heavy years. Combined with moderate fire blight, rust, and mildew susceptibility, the cultivar's overall disease profile is among the weakest in current commerce. The yellow fall color and pure-white bloom give it legitimate ornamental value when healthy, but the disease cost is real. Use this cultivar only when (1) fruitlessness is non-negotiable, AND (2) the planting site can support regular preventive fungicide rotation, OR (3) the planting location is far enough from other Malus and Sorbus to reduce inoculum pressure. For a fruitless or near-fruitless alternative with better disease resistance, consider ‘Indian Summer’, ‘Pink Princess’ (very sparse fruit), or ‘Madonna’ (white double flowers, low fruit). For better disease resistance with moderate fruit production, ‘Adirondack’ or ‘Prairifire’ are better choices. The cultivar blooms early in the crabapple sequence (~155-209 GDD50, synchronous with ‘Coralcole’), so it can pair with later-blooming cultivars for extended ornamental coverage but does not contribute to fruiting-apple pollinizer rotation due to fruitlessness.
