The magnolias at Roland's Wood are some of the earliest cultivars developed by Ozzie Blumhardt, a renowned Northland plant breeder, specialising in magnolias and camellias. Roland visited his nursery at Pakaraka and purchased newly developed cultivars for the Wood, including the now world famous Magnolia Star Wars - Roland was one of Ozzie's earliest clients.
