Fun, weird, helpful, or little known fact

Senecio serra’s long, narrow, serrated leaves distinguish it from the equally tall Senecio triangularis, whose leaves, you guessed it, are more triangle-shaped and have bigger teeth.  The latter seems also to require more water, and is often seen in the company of bluebells, larkspur, and monkshood.
