Stefan Sagmeister's aesthetic approach is often considered more punk rock than anything else. The graphic designer is known for underscoring beauty with a brash dissonance—he once designed a lecture poster with letters carved into his chest with a knife. However shocking, his style is versatile; he's also a poet, an inventor, and, literally, a landscape designer and botanic artist. The message is in the medium, and sometimes the only appropriate medium is floral.
On the language of botany, I imagine many plants would gladly elaborate if they could. Though they lack a traditional (or human) grammatical structure, plants do have a language. They exchange nouns and verbs for colors and shapes, a visual code by which they variously attract, repel, and generally speak to an audience that includes pollinators, each other, and us.
