* Blue flax - love this flower. One year, the entire flower box (8x4 foot) was ALL blue flax. It was gorgeous and I could see the blue flowers from the end of our road as I made my way home. Now they sprout up in all sorts of places from seeds blown in the wind and I let them grow wherever they show up!
* Blanket flower - they use this flower to help reclaim harsh areas along roadsides.. it's a 3-4" tall plant with daisy like flowers that are reds and yellows... I have a ga-zillion blanket flower seeds this year!
