Robert Marchessault is a Canadian painter focused mainly on natural forms. For over 35 years he has painted in series, small and large, that act as investigations of living plants, especially trees. These series are done concurrently, each one takes a different approach to expressing the artist's love for his subject. The series are ongoing and consist of abstractions, allusions, landscapes and isolated subjects.
Marchessault is represented by top galleries in Montreal, Toronto, Vancouver, Seattle, Santa Fe NM, Scottsdale AZ, Calgary AB, and Ottawa ON.​​

"Never was the image of a single tree capable of conveying a whole story, as if every one had a personality, and occupied its space in a special mood. Loneliness, suffering, pride, repose. "
Ben Pastor 2019, in a letter to the painter (Pastor is the author of the Martin Bora novels, Martin Quigley Publisher)
