Chrysanthemums are a must-have for the fall garden. No other late-season flower delivers as much color, for as long and as reliably as good ol' mums. Beautiful chrysanthemum flowers, available in several colors, bring new life to a garden in the fall. Some varieties have daisy blooms; others may be rounded globes, flat, fringed, quill shape, or spoon shape. They work exceptionally well in container plantings and pots.
