West, Todd P. | Morgenson, Gregory | Chaput, Larry | Herman, Dale E.
Herman is a new cultivar of Pinus cembra L. (common names include Swiss Stone pine, Arolla pine, Swiss pine, Stone pine, or Austrian Stone pine). Its lateral branches curve markedly upward and slightly inward, resulting in a narrowly erect, strikingly dense growth habit. ‘Herman’ (original selection) is ≈12 m in height with a spread of 4.5 m after 40 years. Average growth is 15 to 30 cm per year with typical average height of 3 m after 10 years. It is adapted to USDA plant hardiness zones 3 to 7 and performs well on a wide range of soil types. Pinus cembra is a five-needled pine with year-round rich-emerald-green color, with silvery-blue overtones. ‘Herman’ (Prairie Statesman®) is extremely cold hardy and drought tolerant, making it an excellent choice for an evergreen specimen planting in low-input landscapes without supplemental irrigation.
