Lanscape Design for DraftSight?

Anybody know how where I can get a library of CAD Plant images for 2D Landscape Design in DraftSight. Not sure of the proper lingo. Am I looking for Hatches or Blocks or Something else? I would like to illustrate different plant materials on a 2D landscape Plan. I've tried searching but I'm not sure I'm using the write terminology for what I'm looking for.
