The Rosetta Stone. The Blarney Stone. The Rolling Stones. Elphinstone? This strain does not come straight out of J.R.R. Tolkien, though users may find it enhances their reading. Rather, this sativa-dominant bud is a cross of Appalachia with Sweet Skunk. Long-lasting flavors of sweet skunk are pungent, with notes of lemon-lime that are as uplifting as the bud’s effects.
