The three artists in the April show at River Gallery, 400 E. Second St., have cultivated an interest in plant life to inspire their works. Caesar Citraro of Michigan observes both detailed and abstracted elements of the environment in his oil paintings, such as "A Moment in Time," left. Kim Kauffman produces her series of digital prints, such as "Squash Blossom," bottom left, with a flatbed scanner. Steve Noggle pays homage to trees by using the organic edge of the original trunk in his hardwood-turned bowls, right. Their exhibit, "Nature at Its Best," opens with a reception from 6:30 to 8:30 p.m. Friday, April 4. The show continues through Wednesday, April 30. Gallery hours are 10 a.m.-5 p.m. Monday-Saturday, 1-5 p.m. Sundays. For more information, call 423-265-5033, ext. 5, or visit www.river-gallery.com.
