Carolina Bushpea is a Southest U.S. native, found growing wild in forest clearings. It will grow well in most areas, although it is a slow starter from seed.
For best results, give the plant plenty of room to grow. It can dominate the border in early spring with its size and striking flowers.
Can tolerate some dryness, although it will do best with moist soil. Has a long taproot, and does not transplant well.
This plant has been said to grow in the following regions:
Pike Creek, Delaware Lula, Georgia Rincon, Georgia Bar Mills, Maine Cape Elizabeth, Maine Bridgewater, Massachusetts Cordaville, Massachusetts Nelson, New Hampshire Richmond, New Hampshire Frenchtown, New Jersey Pennsauken, New Jersey High Point, North Carolina East Norriton, Pennsylvania Glenside, Pennsylvania West Grove, Pennsylvania Lincolnville, South Carolina Hood, Virginia
