Malus 'Jack Humm'
 
A small, deciduous tree with a dense round form
 
Rosy-pink buds open to white flowers in early to mid-Spring. These are followed by orange-red plum-sized fruit that persist late in the season. This variety makes an excellent Crabapple Jelly and the larger fruit are easy to pick. 
 
Leaves emerge bright green, turning dark green in Summer and shades of orange and yellow for Autumn. 
 
Tree Size
 
Dwarf: Can be kept to 1.5 m high, but must be supported with a stake.
 
Semi-dwarf: Approximately 4 m tall x 3 m wide. 
 
Crabapples are small trees that are hardy once established. Grow in full sun to part shade. Will grow well on most soils, but prefers a deep, moist, loamy soil.
 
Pruning requirements are minimal. Prune in winter to achieve a good shape in the early years.
 
Crabapples are self-fertile, and make useful pollinators for eating and cooking apples.
