What The Petunia Knows (Tom Ashbrook, On Point)

We ooh and ahh over flowers, fields of green, begonias, sequoias, even the humble petunia.  But it’s easy to underestimate a plant.  My guest today says it’s no use playing them Mozart.  They’re deaf as can be.  But by a whole lot of other measures, plants are wide awake and really  paying attention.
They can see when you come near them.  Feel when they’re touched.  Smell what’s going on around them, and respond.  And they remember.  In their own way, not entirely different from humans, they know what’s going on.  Tobacco.  Cherry.  Willow.  Chrysanthemum.
