Rhus copallinum

Winged Sumac features yellowish-green flowers blooming July-August. It is dioecious, with male and female flowers on separate plants. Both male and female plants are needed to produce fruit. Flowers provide nectar for native bees. Fertilized female flowers lead to large clusters of edible, sour, red berries which ripen in August. The berries provide a valuable food source for birds. Fall foliage is a rich red, crimson, and scarlet. Winged Sumac provides habitat for birds, bees, and wildlife. Use Winged Sumac in dry rocky places, coastal gardens, along stream banks, in naturalistic plantings, and in large areas of your yard. It will spread to form colonies.

Rhus aromatica

Fragrant Sumac features yellow flowers, which bloom March-April. It is monoecious; male and female flowers appear separately on the same plant. Female flowers produce berries, which are eaten by birds. Leaves and twigs are aromatic when bruised. Fall foliage is orange to red to reddish-purple. Branches will root themselves where they touch the ground. Fragrant Sumac is a host plant for butterfly and moth larvae (caterpillars), including Red-banded Hairstreak (Calycopis cecrops). Use Fragrant Sumac in mass plantings, foundations, borders, and for stabilizing slopes.

Rhododendron viscosum

Swamp Azalea’s fragrant clusters of white to pale-pink flowers with extended stamens bloom mid-May-July. The flowers have a clove-like scent, and the nectar is attractive to bumblebees. Swamp Azalea leafs-out before blooming. Its native New Jersey habitat includes swamps and bogs, so it prefers a moist substrate in a partly shady area in your yard. Swamp Azalea is flood-tolerant, but is intolerant of juglones (chemical in the roots of Black Walnut). Use Swamp Azalea in rain gardens, woodland gardens, shade gardens, and massed in shrub borders. As with many Azaleas and Rhododendrons, all parts of this plant are poisonous.

Rhododendron periclymenoides

Pinxterbloom Azalea, or Pink Azalea, features fragrant clusters of cotton-candy pink to white flowers, which bloom in April to early May, before leaves emerge. The nectar is a valued food source for bumblebees. Plant it in well-drained soil — it does not tolerate “wet feet,” and poor drainage leads to root-rot. Pink Azalea spreads by stolon (a horizontal plant stem or runner that takes root at points along its length to form new plants). Use it in shrub borders, foundation plantings, shade gardens, natural areas, or as a hedge. As with many Azaleas and Rhododendrons, all parts of this plant are poisonous.

Rhododendron maximum

Great Laurel is a broadleaf evergreen shrub or small tree. Clusters of white to purplish-pink flowers bloom in June, providing a valued food source for bumblebees. Use Great Laurel in shrub borders, foundation plantings, and natural areas around your yard. As with many Azaleas and Rhododendrons, all parts of this plant are poisonous.

Rhododendron catawbiense

Catawba Rhododendron is a broadleaf evergreen shrub. Large clusters of lilac to purple to rose flowers bloom April-June, providing a valued food source for bumblebees. Use Catawba Rhododendron in shrub borders, foundation plantings, and natural areas around your yard. As with many Azaleas and Rhododendrons, all parts of this plant are poisonous.

Rhododendron atlanticum

Dwarf Azalea is a low-growing, colony-forming shrub. Long-stalked clusters of fragrant white-pink flowers bloom April-May and provide a valued food source for bumblebees. Use Dwarf Azalea in shrub borders, foundation plantings, and natural areas of your yard. As with many Azaleas and Rhododendrons, all parts of this plant are poisonous.

Rhododendron arborescens

Sweet Azalea features clusters of white-pink flowers with protruding red stamens, which bloom June-July. Its nectar is a valued food source for bumblebees. Leaves turn reddish-purple in the fall. Use Sweet Azalea in shrub borders, foundation plantings, and natural areas in your yard. As with many Azaleas and Rhododendrons, all parts of this plant are poisonous.

Rhexia virginica

Handsome Harry lives up to its name! Rose-pink to pale-pink petals surround yellow stamens to create an attractive flower, which blooms in May-September. It is cross-pollinated by bumblebees, which forage for its nectar and pollen. Its leaves contain “pulegone,” and can be rubbed on your skin to repel mosquitos. Handsome Harry is an important host plant to larvae (caterpillars) of the Large Lace Border moth (Scopula limboundata). Old seed heads offer shelter for over-wintering beneficial insects, which in turn provide food for birds in the spring. Handsome Harry prefers wet peat or sandy acidic soil. It grows best on the edges of moist woodlands or meadows. Plant Handsome Harry in masses along borders, beds, and moist natural areas of your yard. It propagates through self-seeding.

Pycnanthemum muticum

Clustered Mountainmint is a wildlife-friendly perennial, which features tubular pink flower clusters blooming July-September. It tolerates bright shade, but produces more flowers in full sun. It grows in densely-leaved clumps that may spread vigorously. Clustered Mountainmint is a valued nectar source for butterflies and bees. It attracts beneficial predatory insects that prey on garden pests. Clustered Mountainmint is most attractive when massed, and can be used in your herb garden, butterfly garden, or in mixed borders around your yard.
