I have a hard time walking past a greenhouse. Or chocolate. And ice cream.
This picture shows the Buckhout Greenhouses. I didn't have time to go inside to see what the purple flowers were. These greenhouses are now managed by the Biology Department at Penn State but with so much interdisciplinary collaboration facilities across the campus are usually available to scientists and students regardless of their academic homes. The Department of Plant Pathology is in Buckhout Lab and attached to these greenhouses.
While searching for information about the Buckhout Greenhouses I came across a USERS GUIDE. Things are far more complex that they seem.
I also won't pass up a dog who needs a pat on the head.
