Longtime Dupont Circle resident Michael Rawson has always been interested in painting, but his retirement a few years ago has given him more time to get serious about it. And the dedication is paying off — the 64-year-old Quakertown, Pa., native has seven of his oil paintings in the new exhibit “Beyond Words: The Symbolic Language of Plants” which opens this weekend at the Delaware Art Museum in Wilmington and runs through April 8.

Rawson is a member of Studio 155, an artists group that formed after its 17 members took classes together at the Corcoran Gallery of Art and collaborated on the 2006 exhibition “Botanical Treasures of Lewis and Clark.” Together their work is featured in the large Delaware exhibit. They work “to realistically capture the natural world while expanding the boundaries of botanical art.”

“I always loved plants,” Rawson says. “My mother is a good gardener. … And trees are our tallest and biggest plants. They are what give us life — the air we breathe, the food we eat, the shelter, our clothes. So that was my inspiration.”

Rawson spent most of his career as a pre-school teacher and says he “always worked well with young children.”

He came to Washington in 1966 to attend George Washington University. He and partner Gordon Binder, a senior fellow at the World Wildlife Fund, have been together 38 years. They attribute the longevity of their pairing to “companionship, intimacy, friendship, common interests and enough differences to keep it lively.”

Rawson enjoys water aerobics, reading, watching TV, quiet evenings at home and, of course, painting, in his free time. Go to delart.org for more information on the exhibition. The museum is at 2301 Kentmere Parkway in Wilmington.

How long have you been out and who was the hardest person to tell?

In my head, since sixth grade. But in fact not until I met Gordon, and then we fell in love. My father. I learned how upset he was when he recognized that I was gay (I had left home by then). Years later, at Christmas, when Gordon gave me our paid mortgage in a box, my father said, “He’s a smart man,” and I knew he had embraced us both.

Why Washington?

I came to school in Washington, GW, in 1966. A few years later, I met Gordon when we were interns at the Council on Environmental Quality and a little over a year later we hooked up and we made our life together. We’ve lived in Dupont Circle, one of the great urban neighborhoods anywhere. We value the cultural scene, the lively street life, so many places to go and things to do, and of course the friends we have here.
