Autumn is a wonderful time in the flower garden. Autumn joy sedum, fall blooming asters, coreopsis and goldenrod abound, but my favorites by far are chrysanthemums. Many garden centers offer annual mums in the early spring, but I am particularly fond of perennials, and have been in search of reliable, hardy, colorful mums to include in my fall garden. Plant breeders at the University of Minnesota have introduced a number of beautiful chrysanthemums that will bloom in early autumn. Bloom time is the key. Some mums are northern hardy, but set buds so late that the first killer frost occurs before they have a chance to bloom.
The U of M, considered a national leader in mum breeding, has produced a number of selections for northern gardeners. Among them are the low maintenance “My Favorite” series with frost-tolerant blooms. These monster plants grow up to 4 feet tall and are 3 to 7 feet in diameter by the second year. They all have daisy type flowers and come in a variety of colors. “My Favorite” autumn red has maroon petals with a gold center. “MF” coral has coral petals with a gold center. “MF” twilight pink flowers are pink with a gold center. “MF” white has a semi-double daisy flower with white petals and a gold center, and “MF” yellow quill has yellow quilled petals with a yellow center. Each of these is a cushion mum, with a hemispherical growth habit and flowers that almost completely cover each plant.
The “Minn” series of cushion mums are early bloomers and also come in a variety of colors. Minngopher is ruby-red with 2” to 2-1/2” flowers. Minnqueen is rose-pink with 3” flowers. Minnrose is rose-pink with a 1-1/2” pompom. Minnruby is ruby-red with 2.25” flowers. Minnwhite has 2” flowers, and Minnyellow has 2” lemon-yellow flowers.
Beyond the “Minn” and “My Favorite” series, other hardy mums produced by the University of Minnesota include: peach centerpiece, a 4-inch single quill bloom with a yellow center; rose blush, an early upright; sesquicentennial sun, a new long-flowering yellow double; and Betty-Lou, a striking red button mum with flowers averaging 2-1/2 inches in diameter.
