Rod Saunders and his wife Rachel Saunders were co-owners of Silverhill Seeds, a company specializing in South African seeds and also selling books. Throughout much of the year they traveled around South Africa collecting seeds. For a number of years Rod and Rachel had been locating and photographing Gladiolus species, including elusive species not easily found in the wild, in order to write a book. Rod was a long term member of the committee and former chairman of the Indigenous Bulb Association of South Africa, a first rate photographer, and a popular speaker. While out collecting February 2018 in Northern KwaZulu-Natal, they were murdered by terrorists.
The spring 2018 issue of the PBS Bulb Garden was dedicated to their memory.
