Don’t be deceived by the flat farmland along NC 231 as you make your way across Johnston County toward Flower Hill Nature Preserve. A surprise — a “freak of nature” — awaits down the road. Discover a 25-acre nature preserve owned and managed by Triangle Land Conservancy to protect rare populations of rhododendron, galax, and other montane plants. Early May is typically when the magnificent pink Catawba rhododendron blooms. In addition to great plants, the endangered dwarf wedgemussel inhabits the creek next to Triangle Land Conservancy.
