> > Any thoughts on this? Can this species be variable? Or is it likely something else? A pot of plants sown in 2008 has 14 dark and pustulate plants and 2 smooth, green leaved plants. The pot sown in 2010 and just germinating has leaves that are green and smooth. All of these come from my plants that are very dark leaved and very pustulate. Can't find the 2009 sowing.
