The trick to designing your garden with perennial flowers is making sure you have something wonderful in bloom all the time. Each season has its stars and fall flowering perennials have some of the best. Fall flowers have all season to grow, so many of them are tall and stately. Fall bloomers also tend to blossom in the jewel tones of the season, deep purples, rusts, scarlet and gold. For fall bloomers to be hardy in your garden, you need to plant and establish them earlier in the season. Here are some top picks for fall blooming perennial stars.
In shades of pink, purple, blue and white, these delicate daisy-like blossoms start popping open in late August and continue on until frost. Pinching in the early summer turns these Asters into mounds with dozens of flower buds.
Asters will tend to creep throughout your garden, but their airiness allows them to blend particularly well with other flowers. USDA Hardiness Zones 4 - 9
Caryopteris is a sub-shrub that is often grown in the perennial garden. Caryopteris slowly blossoms in August with dazzling blue flower clusters. Just try and keep the butterflies and bees away. Caryopteris is cut back in early spring, like a Buddleia, and the gray-green foliage is attractive all season. USDA Hardiness Zones 5 - 9
Nick-named for their blossoms shaped like turtles heads, Chelone is a carefree fall blooming perennial whose only real dislike is excessive dry heat. Chelone behaves itself, growing in a dense clump with attractive foliage and red, pink or white blooms. USDA Hardiness Zones 2 - 9
Helenium is making a resurgence in gardens. They look like small russet-toned coneflowers, in reds, yellows and oranges. Many helenium can grow quite tall and will need to be staked or pinched. Like clematis, they like cool feet and hot heads. Helenium is also a good choice for poorly drained areas. USDA Hardiness Zones 3 - 9
Helianthus is a good natured, jolly plant, branching and flopping on its neighbors. The brilliant gold fluffy daisy-like flowers make an instant focal point and attract butterflies and birds. Helianthus tend to be sterile and can be reproduced by division. USDA Hardiness Zones 3 - 9
Goldenrod is finally getting the respect it deserves, especially with introductions like 'Fireworks' and 'Golden Fleece'. Unlike the native solidagos that spread everywhere and never stood up on their own, these newer varieties are sturdy and chock full of fall blooms. USDA Hardiness Zones 3 - 9
