Grow your own hops with a rhizome root stock.
Centennial is an American dual-purpose variety with high alpha acids (9.5-11.5%) and excellent aromatic capabilities. It's widely used as a finishing or dry hop as a stand-alone variety or part of a blend. The flavor and aroma notes are predominantly citrusy but with undertones of lemongrass and pine needles often evident. Used in styles such as pale ales, IPAs, stouts, blonde ales, and wheat ales.
Cascade, Magnum, and Nugget hops are the recomendated hops for beginner growers.
