Winecup  Callirhoe involucrata
The wine-colored blooms of this low-growing perennial make a beautiful addition to home 
gardens, providing spring and early summer color across the prairie states from Texas to 
North Dakota and as far west as Utah. Rosettes remain green in the winter. In the photo at 
left, a beneficial soldier beetle (cousin to the lightning bug) is at work.

Winecup, AnnuAl Callirhoe leiocarpa   
We stumbled upon this beauty on a backroad not far from the farm. Growing along a 
wooded edge, we gathered a few seeds and planted them the day after 9/11. Easy to grow, 
serves as a great reminder that each of us has the right and responsibility to create a little 
spot of health on an ailing planet.

White RosinWeed Silphium albiflorum
Great pollinator plant! Blooms in the hottest time of year when few other resources are 
available. This is one of the most surprising and interesting wildflowers of the prairie. 
Sometimes called Compass Plant, leaves align in a north-south direction, exposing their 
large, flat surfaces to as much sun as possible. Large, deep perennial taproot. Texas endemic.
