I am the Horticulturalist for Historic Columbia and a USC Alumnus! I am not aware of your efforts or of your group, but I have been embarking on exactly the same quest to repatriate plants to Columbia. I have already secured a donation of the Herbemont grape from Texas A&M thi winter, but have been so far stumped in the search for Hick's Mulberry as well. Would you be interested in sharing information and progress? I would love to know who your collaborators are and how you got started!
