Today I’m returning to snowy Pittsburgh where the sky may be overcast, and ice coats the sidewalks. As I board the plane in Florida, I remember my afternoon at the Naples Botanical Garden when my friend Marjorie walked around the lake on the lookout for alligators. I told Marjorie that I was admiring the textures of the grasses and pines. Marjorie replied, “I’m looking for color.” A few minutes later, I spotted this brilliant red orchid growing in the limbs of a tree. I liked the way the smooth white bark of the three tree limbs framed the plant.
