Trillium grandiflorum Graham Spillers but when winter temperatures dropOffered for the first time in 2021, Trillium 'Graham' are nursery seed propagated, flowering sized plants of the highly prized Trillium grandiflorum. This offering is for plants 6 7 years old and grown from seed collected in Graham County, NC, just south of Knoxville, TN. Each stalk is topped with three green leaves and a single triangular white flower, starting for us in mid April. Rich woodland soils are best with a pH tending toward neutral.
