Overview
A genus of approximately 35 species of deciduous trees grown in Pacific Northwest gardens for spectacular spring flowering, ornamental small fruits, and multi-season interest. Ornamental crabapples range from 8–25 feet (2.4–7.5 m) tall with habits from weeping to columnar to broadly rounded. Spring flowers in white, pink, rose, or deep red-purple, 1–2 inches (2.5–5 cm) across, in April–May; many are fragrant. Small fruits 0.5–1 inch (12–25 mm) diameter in red, orange, gold, or yellow, ripening in fall and often persisting through winter to provide bird food. Apple scab (Venturia inaequalis) is the primary disease concern in the wet Pacific Northwest — disease-resistant cultivar selection is critical. Seeds mildly toxic to pets. Hardy in USDA zones 4–8.
Native Range
The genus Malus is distributed across the temperate Northern Hemisphere. Most ornamental cultivars are complex hybrids involving Asian species, particularly M. baccata (Siberian crabapple), M. sargentii (Sargent crabapple), M. floribunda (Japanese crabapple), and others.Suggested Uses
Planted as specimen trees, street trees, or wildlife-supporting trees at spacing matched to cultivar mature size. No other commonly grown small deciduous tree combines spring flower display, ornamental fall fruit, bird-supporting value, and variety of form in a single plant. Select disease-resistant cultivars for the Pacific Northwest. Seeds mildly toxic to pets if consumed in large quantity.How to Identify

Bloom Information
Blooms in April–May, typically for 1–2 weeks. Flower color ranges from pure white through pale pink, rose, and deep red-purple depending on cultivar. Many cultivars are fragrant. One of the most spectacular brief flowering events among commonly grown Pacific Northwest landscape trees.Detailed Descriptions

Care & Maintenance
Care Guide
Plant in full sun in well-drained, slightly acidic soil (pH 5.5–6.5). Full sun essential for disease resistance and best flowering. Space according to mature size of the selected cultivar (8–25 feet/2.4–7.5 m). Water regularly during establishment; moderately drought tolerant once established. Select disease-resistant cultivars — susceptibility to apple scab (Venturia inaequalis) is the primary limitation in the wet Pacific Northwest climate. Resistant cultivars include Malus 'Prairifire', Malus 'Sugar Tyme', Malus 'Camelot', and Malus 'Robinson'.Pruning
Prune in late winter (February–March) before growth begins. Remove dead, crossing, and water-sprout branches. Maintain open canopy for air circulation to reduce disease pressure. Avoid heavy pruning — crabapples respond with vigorous water sprout growth that increases fire blight risk.Pruning Schedule
