Herbaria 3.0 emerged in part to counter an epidemic of “plant blindness,” or the inability to seethe plants that surround our everyday lives. Without recognizingthe plants around us, we cannot recognize that plants are essential: they give us medicines and metaphors, gardens and garlands, perfumes and poetry. Yet plants are not just objects for our fascination or use: they have their own wants, needs, and desires. They exhibit complex behaviors in response to equally complex stimuli. Plants exist in a world of complex relationships that are often hidden from human view.
