Mums make a good impression no matter what you're looking for in a fall flower.
The versatile mum
When fall arrives, it's hard not to regret the passing of all the summer blooms we love so much: pompon dahlias, Shasta daisies, African daisies, little zinnias, asters, coreopsis, and calendulas.

Red mums star in this fall garden with asters and ornamental grasses.
But take heart, for the fall garden offers all these flower shapes from just one plant, the chrysanthemum. Hundreds of hardy cultivars provide an array of colors and bloom shapes, making mums the divas of the autumn garden. The blooms last for weeks, not days, and the sheer number of flowers per plant will convince anyone that this flower really likes to show off. Add the mum's impressionistic abilities to its longevity, and you have a plant that pulls its weight in the garden.
Because of their tight, mounded habit and stunning bloom cover, garden mums are perfect for mass plantings. To get the maximum effect from far away, stick to only one or two colors. Another possibility is to arrange a gradual transition of related colors. Look around your yard to see what colors would best complement the existing landscape.
