The Cass Turnbull Memorial Scholarship

PlantAmnesty's late founder, Cass Turnbull, was a champion of horticultural education and students of all skill levels. She provided space and opportunities for marginalized groups to have access to plants and plant care. To spread the love she had for pruning and to keep her legacy alive, PlantAmnesty is offers a limited number of full scholarships toward our Master Pruner Program each year.
