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 mucronulatum

Korean Rhododendron is a deciduous shrub, which is unusual for Rhododendrons. It features rosy-purple flowers which bloom in early spring, from mid- to late-March to early April. Situate this plant in a northern exposure in the yard or garden to avoid blooming too early, as buds are susceptible to frost. Use Korean Rhododendron in shrub borders, foundation plantings, or natural areas. 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.

Quercus velutina

Black Oak is a medium-tall, deciduous tree of the red oak group. Its shiny dark green leaves have deeply cut lobes. The bark is almost black on mature trunks, giving it its common name. It prefers moist, organically-rich soil, but tolerates nutrient-poor, dry soil. Acorns provide food for birds and wildlife. Oaks are host to numerous beneficial insects, which in turn provide food for birds. Black Oak is a host plant for butterfly and moth larvae (caterpillars), including Edwards Hairstreak (Satyrium edwardsii). It provides nesting space, cover, and shelter for wildlife. Use Black Oak as a street tree, shade tree in large lawns or parks, or in natural areas around your yard.

Quercus stellata

Post Oak is a medium-sized, deciduous tree of the white oak group. It has rough, leathery, dark green leaves with a cross-shaped appearance. Fall colors are variable, and can be bright yellow. It takes up to 25 years for Post Oak to reach maturity and bear acorns, which provide food for birds and wildlife. It is a host plant for butterfly and moth larvae (caterpillars), including Northern Hairstreak (Satyrium favonius ontario), and Horaces Duskywing (Erynnis horatius). Post Oak tolerates a wide variety of soils, is low-maintenance, and long-lived. Use Post Oak as a street tree, shade tree, or lawn tree in your yard.
