As the sun beats down on the black asphalt, one might wonder is there any plant life here? Can I even eat any sort of plant life here? The “fruit” smoothies, after all, are mere mirages of flavored juice and ice, and the curly fries sweaty siblings of their potato predecessors.And yet, at the WSU Master Gardeners exhibit tucked into the back of the Exhibition Hall, you might find yourself getting back to the real roots of food and nibbling on plants straight out of the garden. The exhibit, new to this year’s fair, is out to prove that growing an attractive and edible landscape doesn’t require a green thumb or a ton of space.
