Trillium rivale 'Purple Heart ' was found by Boyd Kline and has the largest flowers of any rivale that I've encountered. Unfortunately many are the poor impostors that have been grown from seed which in no way look like the wonderful original. T rivale ' Del Norte' was also named by Boyd Kline or his former business partner Lawrence Crocker of the Siskiyou Rare Plant Nursery. It was a particularly robust pink form that multiplied rapidly. I believe it only had a few madder colored spots on the corolla unlike 'Purple Heart'.
