June 2010, week 5

June 2010, week 5

Welcome to the first installment of "Name That Native", a plant ID blog from the Blomquist Garden of Native Plants at the Sarah P. Duke Gardens! This will be a weekly blog focused on the identification of our southeastern United States native flora. Each week I'll add between ten and fifteen new native plant names along with a botanical description of some of their characteristics, native range, etc. Each latin name will be linked to a page for the species on the USDA plant database where you can see photos and range maps for each plant. My assistant, Katherine Wright, will be using this blog to help build upon her native plant knowledge, and you can follow along as well. Enjoy! Confused by some of the botanical terms? (example: "Cauline") Use this website to learn what those indecipherable descriptions mean.
