No but they will grow there, birds spread them. They make a great hedge and you can trim them to any height.
Hello.. I think the Rose of Sharon are pretty. My house I used to live in back in the late eighties and nineties had a Rose of Sharon plant. I live in Ohio so, they are here too, and Pennsylvania is my next door neighbor. So the birds must of spread them here too!
lucky you!! If you dig up a special space in the sun & replant all of them there, you can watch them grow & give for gifts or sell at flea Mkt
I grew up with Rose of Sharons (white, pink and darker pink), too, in Indiana. Now, here in Michigan, I have a beautiful blue Rose of Sharon.

Common Names: Rose of Sharon, althea, althea rose, shrub althea, shrubby Althea, Syrian rose
Native Origin: eastern Asia- China to India; introduced as an ornamental and often used as hedging
Description: A deciduous, multi-stemmed, erect-growing, densely branched shrub in the Mallow family (Malvaceae) reaching up to 10 feet in height with a pyramidal crown. Light gray-brown stems have raised leaf scars, hairy stiplues and small buds. Ovate green leaves are 2 to 3 inches long, palmately veined from the base, alternate, simple, coarsely serrated and often three-lobed. Showy, 5-petaled flowers range from white to reddish-purple, 3 to 4 inches across, and bloom during the summer months. The flowers are perfect (have both male and female organs) and are pollinated by insects and hummingbirds. Brown seeds develop in an ovate, pointed, dry capsule, 3/4 inch long and wide, ripening in late summer and fall. This prolific seeder has a deep taproot that is difficult to remove once the plant is 2-3 years old. It reproduces primarily by seed.
Habitat: It grows in full sun to light shade and invades waste areas, disturbed ground, forest, and forest edges. It prefers a well-drained humus rich fertile soil within USDA zones 5-10.
Distribution: This species is reported from states shaded on Plants Database map. It is reported invasive in KY, PA, TN, and VA.
Ecological Impacts: It has escaped intended plantings to invade, crowd out and displace more desirable native plants.
Control and Management:
NOTE: Sterile cultivars for rose of Sharon: ‘Diana’ [Gold Medal Award], ‘Helene’, ‘Minerva’’, are available at the U.S. National Arboretum, bred by Dr. Egolf.
