Selected Works

“The temple bell stops.

But the sound keeps coming

Out of the flowers.”

Matsuo Bashō (1644–1694)

I grow my own botanicals—the models for my artwork—or purchase them from local greenhouses that sell the flowers, fruits, and vegetables produced in the rich farmland of this region. We are fortunate to live in an area that is a major North American bird race, and the birds in my images are found in our gardens. My art is carefully created by hand in watercolor, pastel, pen and ink, and graphite using time-honored natural science illustration techniques.
