Hello Gardeners, I’m Amanda McNulty with Clemson Extension and Making It Grow. Tilia americana has the common names of linden or basswood. Basswood, b a s s is a corruption of bast – b a s t. Bast is the fibers from the phloem of woody plants, the outer layer of the vascular system. If you search a plant at NRCS Plant Guide, you get the North American ethnobotanical uses of the plant. : Native Americans and settlers used the fibrous inner bark ("bast") as a source of fiber for rope, mats, fish nets, and baskets.
