Red Chokeberry

A

Aronia arbutifolia

Red Chokeberry is a vase-shaped shrub related to apples, cherries, and roses. Preferring moist acid soils, it has surprising tolerance to high pH and drought. Its bright red, edible fruits are high in antioxidants, though not as nutritive as the fruits of the related Black Chokeberry (Aronia melanocarpa). Its fruits are extremely tart when eaten raw, but can be used to make jellies, jams, preserves or in baking.

Height: 6 to 8 feet
* Spread: 3 to 4 feet
* Growth Habit: Deciduous, upright, vase-shaped shrub; suckers to form colonies
* Sun/Shade Requirements: Full Sun to Part Shade
* Cultural Tolerances: Prefers moist well-drained soils, extremely flood tolerant, somewhat drought tolerant.
Grows best in acid soils but can
tolerate soil pH up to 8.0.
* Ornamental Characteristics: Bears glossy green leaves which turn a showy scarlet in fall. Produces clusters of white to light pink flowers in early spring that mature into glossy, bright red berries.
* Pests and Diseases: No serious
pests or diseases. Occasionally
susceptible to leaf spots and twig/fruit blight.
* Deer Resistance: Occasionally
Severely Damaged
* Ecological Effects: Flowers are
utilized by several pollinator species.
Fruits of this plant are eaten by several species of birds and some small mammals.

* Spread: 3 to 6 feet
* Growth Habit: Deciduous, upright, rounded shrub; suckers to form colonies
* Sun/Shade Requirements: Full Sun to Part Shade
* Cultural Tolerances: Prefers moist well-drained soils, extremely flood tolerant, somewhat drought tolerant.
Grows best in acid soils but can
tolerate soil pH up to 8.0.
* Ornamental Characteristics: Bears glossy green leaves which turn a showy scarlet in fall. Produces clusters of white to light pink flowers in early spring that mature into glossy, dark
purple-black berries.
* Pests and Diseases: No serious
pests or diseases. Occasionally
susceptible to leaf spots and twig/fruit blight.
* Deer Resistance: Occasionally
Severely Damaged
* Ecological Effects: Flowers are
utilized by several pollinator species. Fruits of this plant are eaten by several species of birds and some small mammals.

Buttonbush

A

Cephalanthus occidentalis

Buttonbush is a medium to large upright to arching shrub with a coarse texture derived from its simple, shiny leaves that are 4-6”
long. Native to wetlands in Eastern North America, it nevertheless can survive in dry habitats as well. In addition, it is tolerant of salty soils and salt spray. Buttonbush is late to leaf out and may be cut back in early spring to keep it in a more compact habit. ‘Sugar Shack’
is a smaller more compact form of Buttonbush.

Q

Common Snowberry

A

Symphoricarpos albus

Snowberry is native to wooded hillsides and rocky slopes, with
average soils, but can adapt to a wide range of poorer soil conditions.
It has sparse branching, eventually forming a thicket, spreading by
suckers. This makes it useful as an erosion control plant. Berries
ripen to be white and marshmallow-like, and often provide some
winter interest, as many bird species do not eat them. This plant
would be best suited for the edges of bioswales, where the soil is
less saturated. Pruning can be done from late winter to early spring,
as needed.

  • Height: 3 to 6 feet

Nannyberry Viburnum

A

Viburnum lentago

Nannyberry Viburnum is a large, upright, multi-stemmed shrub or
single-trunk small tree. It is native to hillsides, stream banks, and
open woods with average, well-drained soil. Fruits are prized by
birds and other wildlife, but are edible to humans as well and can be
consumed raw or made into preserves. Flower buds for the following
year form in summer, so pruning should be done immediately after
fl owering. Selective stem pruning is needed in order to keep its form.
Remove any root suckers as well, unless naturalization is desired.

  • Height: 14 to 16 feet
  • Spread: 6 to 12 feet
  • Growth Habit: Deciduous, upright,
    multi-stem shrub; suckers to form
    colonies
  • Sun/Shade Requirements: Full Sun
  • Cultural Tolerances: Prefers full sun,
    is tolerant of a variety of soils and
    fl ood; somewhat drought tolerant;
    tolerates high pH
  • Ornamental Characteristics: Glossy
    green leaves; umbels of white to pink
    fl owers that mature to dark blue, edible

Possumhaw Viburnum / Smooth witherod

A

Viburnum nudum

Possumhaw Viburnum is a shrub with upright stems, that arch
with age. It is native to savannas, low, wet woods, and bogs, but
is adaptable to a variety of conditions, tolerating only occasional
drought. For the best cross-pollination and fruit display, planting in
groups of more than one variety is recommended. Berries are edible,
though highly acidic, and provide striking color of blues, pinks and
purples contrasting with the foliage. New cultivars show improved
pink and fl ue fruit color and deep red-orange fall color. Pruning may
be done after fl owering, but it will take away from the fruit display at
the end of summer.

  • Height: 5 to 12 feet
  • Spread: 5 to 12 feet
  • Growth Habit: Dense, rounded,
    upright, multistem, deciduous shrub;
    plant at least two varieties to get good
    fruit set
  • Sun/Shade Requirements: Full Sun
    to Part Shade
  • Cultural Tolerances: Requires acid
    soils; prefers moist to wet soils, but
    can handle occasional drought
  • Ornamental Characteristics: Glossy
    green leaves; umbels of white fl owers
