Today while visiting one of the food donation gardens I manage, I stopped by our sensory garden to see what was blooming.

Starting with the basics of grass identification

What do you see when you look at a grass? Green leaves in a bunch? The cause of your allergies? A plant that constantly needs to be mowed? Grasses do not invite easy identification. They are missing the number one useful identification feature – a colorful flower! But that’s not to say that they...
