Soil: Well-drained loam preferred; tolerates other soil textures if drainage is adequate. Alkaline Phoenix soils may cause iron chlorosis. Apply organic mulch, keeping it away from the trunk.
Mature size: Typically 15–25 feet tall and 15–25 feet wide, depending on cultivar and conditions.
Bloom: Late winter to early spring, usually before or as leaves emerge; flowering varies with cultivar and winter temperatures.
Evergreen / deciduous: Deciduous.
Growth rate: Moderate to fast with adequate water; slower under heat or water stress.
