Mums are favorite fall flowers that add weeks of seasonal color to containers, gardens and fall displays. They are also a popular gift plant in garden centers and floral shops. Choosing the right one for the purpose and providing proper care will help you achieve desired results.
Start by selecting the best mum for your gardening goals. You'll find mums labeled as garden, perennial, gift or florist mums. All these names for plants that look alike can be confusing. The answer lies in their response to day length, hardiness and use.
Mums set flowers based on day length. Growers can force them into bloom by covering them to create shorter days that initiate flowering.
Those grown as gift mums, often called florist mums, usually require the longest periods of uninterrupted darkness or shorter days. When these mums are grown under natural daylight, they usually don't flower until late fall or early winter. These late bloomers are usually killed by low temperatures before or soon after the flowers appear in colder areas.
Nurseries selling mums ready to flower in the fall often refer to them as garden mums. These may be perennial mums or "florist" mums forced to flower for fall displays. The intent is to use them as annuals.
Select ones with lots of buds and just a few, if any, open flowers to maximize the bloom time. Place one or two mums on the front steps, plant them in vacant spots in the garden or combine them with other fall favorites in containers.
These garden mums may be hardy and suited to the area. But since all the energy is directed to the flowers, little is left to establish a hardy, robust root system. If you have success overwintering your garden mums, feel free to brag. If your plants don't survive, don't worry. You are using them as a fall annual as they were intended.
Mums sold as perennials are hardy enough to survive the winter and flower in late summer or early fall, providing weeks of color in the garden. They are often sold alongside other perennials, labeled as perennials or promoted as hardy for the area.
