Paw Paw Tree Seeds or seedlings Wanted

Looking for Paw Paw Tree Seeds or seedlings. Have many Jade plant starts and Night Blooming Cerus clippings rooted and ready to trade. I have Purple Cone Flower seeds, will have a bunch of Columbine seeds this summer, plus Mimosa and Redbud tree seedlings popping up in my yard and ready to trade. mhajek@southwind.net Thanks, Colleen
