Late summer into fall can be a vibrant time in the garden. Try these perennials to add some late-season color.

A cool-season flower that can be set out in early spring, sweet alyssum fades in the summer heat, but its clusters of tiny white, pink, or purple blooms will likely cover your garden again in the fall when temperatures stabilize.

Many gardeners may be dreading the cold autumn weather but it is actually the best time to begin planting flowers to ensure you have a vibrant colourful garden next springtime.

Catmint is the ideal low-maintenance perennial for any garden setting. Available in heights ranging from 8 inches to 3 feet tall, the silvery-green foliage has a minty-spicy scent that deer and rabbits tend to leave alone. Spikes of pink or purple flowers appear for weeks in mid to late summer.

Fall flowers are a valuable source of nectar and pollen for butterflies and other beneficial insects at a time when food sources are scarce.
