Maryland's Piedmont Plateau Province has rolling hills covered with woodlands.
Potomac, Maryland is situated in the Upland section of the Piedmont Plateau Province in Montgomery County. This region has clay soil and hilly terrain. The growing season is usually from May 10 to October 10. Rocky outcroppings, stream valleys and hardwood forests beautify the landscape. When colonists first came to Maryland in the 1600s, forests covered almost the entire state. Today's forests have less of the hardwood species and more pine due to reforestation efforts
Trees
Common tall hardwood trees include red, white and chestnut oak, ash, tulip poplar, American basswood, red and silver maples, sweet and river birches, beech, persimmon, sycamore and black walnut. Pine trees include shortleaf, pitch, white and Virginia pines. Smaller trees that occur as forest understory are eastern redbud, flowering dogwood, American holly, serviceberry, crabapple, sassafras and sweetbay magnolia. (see Reference 4)
Vines
Native vines include red-flowered trumpet creeper and coral honeysuckle, which attract hummingbirds; American bittersweet, leather flower, Virgin's bower and Virginia creeper.

Shrubs occur primarily at forest edges, in thickets and as forest understory. Some native tall shrubs are American hazelnut, mountain laurel, staghorn and winged sumac, alder, possum haw and black haw. Medium-sized shrubs include chokeberry, buttonbush, witch hazel, rhododendron, azalea, elderberry, swamp rose, and deerberry.

Groundcovers
Ground-hugging native plants mostly prefer shade or partial shade, and include stonecrop, wood sorrel, moss phlox, mayflower, wintergreen, partridgeberry and wild ginger.
Grasses
Most grasses grow in areas with dry to moist soil types. Common grasses include broom sedge, river oats, Canada and Virginia wild rye, Virginia switch grass, and Indiangrass.
