Handsome shade tree with few troubles and outstanding seasonal interest. Widely adapted to soils and climates, as evidenced by its wide range. Fall foliage coloration varies greatly in timing and intensity among individuals. Rather difficult to transplant in large sizes. Varies widely in hardiness. Select native northern stock for use in North. Horned fruits can be a serious litter problem, dulling mower blades and injuring bare feet.  Also see Liquidambar styraciflua (Shuttle Gum Group).

Malus × 'Adirondack'

[Adirondack Flowering Crabapple]

The Flowering Crabapple is a popular small ornamental tree with an extremely showy flower display in the spring. This variant has a vase-shaped (somewhat columnar) habit, extremely upright branching, and high resistance to apple scab, fireblight, cedar-apple rust, and powdery mildew.

Malus sargentii

[Sargent Crabapple]

The smallest of all Malus species, almost a shrub. Strongly horizontal branching. Tends to be apomictic (seeds develop without fertilization), so is usually very uniform from seed (i.e. clonal). Sometimes flowers and fruits in alternate years. Susceptible to apple scab disease. May require pruning of wayward and crossing branches to maintain a nice form.

Malus × 'Snowdrift'

[Snowdrift Flowering Crabapple]

'Snowdrift' is a vigorous selection that is covered with numerous white blossoms in the spring, which are then followed by attractive orange-red crabapple fruits. Susceptible to apple scab and fire blight. Well-drained heavy loam soils and full sun promote best growth. May look ragged by the end of the summer.
