SUPERTUNIA® Vista Petunia
The best petunia for landscapes. Hands down. Supertunia Vista varieties deliver outstanding performance over the entire growing season, lasting an extra month in southern states and well into fall in moderate climates. They are bred to flower earlier, grow taller and wider, and spread more vigorously than other petunias. No deadheading is needed for these plants to bloom from spring through fall. They do best in part sun to sun conditions – 4 or more hours of direct sun a day and grow up to 2 feet tall and 3 or more feet wide.
