Pink
buds, opening to pure white flowers and a lovely shrub-like form
make Sargent crabapple a good tree for many different landscapes.
Sargent crabapples are resistant to most crabapple diseases and
flourish with a minimum of care.
A
favorite of many growers and arborists, Sargent crabapple has a
unique size and form, growing as a dense, mounded shrub rather than
a tree. Its flowers are fragrant, light pink in bud, opening to
pure white. The fruits are small, shiny, bright red and a favored
food for birds. Although it flowers heavily only in alternate years,
the many attributes of the Sargent crabapple offset this potential
drawback. The tree grows 6 to 10 feet tall and almost twice as wide.
There
are an extensive number of species and cultivars of crabapples with
tremendous differences in leaf and flower color, leaf shape and
vigor. A carefully chosen crabapple can be a delight to the landscape,
but a poor choice could yield an extremely pest and disease prone
plant with more headaches than delights. M. sargentii is
highly resistant to the most serious crabapple diseases
Prefers full sun and moist, well-drained, slightly acidic loams
but is quite adaptable to varying soil conditions. Hardy in zones
4-8.
Suitable
in a wide variety of habitats, including very urban situations.
From backyards to sidewalks, the Sargent crabapple is valued for
its shrub-like form, outstanding flowers and colorful fruits which
are much favored by birds.
Shows excellent resistance to apple
scab, cedar apple rust and powdery
mildew. It shows slight susceptibility to fire blight but it
is not a significant problem in the Northeast. Sargent crabapples
require little maintenance; pruning is seldom necessary except to
remove dead, damaged or rubbing branches.
M.
sargentii 'Rosea' grows taller than species and is more susceptible
to fire blight and scab. 'Jewelberry' looks much like M. sargentii
but flowers and fruits annually and retains its fruits longer.
Almost all flowering crabapples are self-sterile. Most common propagation
is by grafting or budding onto rootstocks chosen for vigor, hardiness
or reduced suckering. Sargent crabapple can also be propagated by
softwood cuttings taken in June/July or by seed. Seed propagation
is frequently used with Sargent, but considerable variation in size
of the progeny can result.
