|sawwort Serratula tinctoria|
I was new to Colorado in fall of 2006 and finding plants for the yard of my new house. So I was looking on the end-of-the-season garden racks for promising marked-down perennials at McGuckin's Hardware Store in Boulder ("Colorado's Favorite Store"!). I chose a pot or two and got chatting with the clerk. She pointed me to the edge of the garden shop where a couple of run-down, sad-looking plants slumped over the edge of their pots and said I could have them, no charge. How could I resist?!
