Wayland Town Crier 8/28/11: 'Wayland A-Z': 'Y' is for 'yucca filamentosa'. There is no proof that this remarkable plant had made its way north before Native Americans came to fish and hunt in the Sudbury River Valley, but it may have. Yucca filamentosa is native to southeastern regions of North America – and there are more than 40 other Yucca species throughout the U.S. and Mexico – but it became well established in the north a very long time ago.
