The Profusion and Zahara series of zinnia produce disease resistant mounds of color that last until frost when planted in late summer. The more traditional flowers of the Dreamland and Magellan series can also be enjoyed at this time of year while avoiding the disease issues that can show up in the spring. All have vibrant colors with the cool nights of fall on sturdy compact plants.
