When summer winds down, your container gardens may be looking past their prime. Perhaps a plant or two didn’t make it — or you have the opposite problem: They did so well that they’re taking over your container (sweet potato vine, anyone?). If this is the case, don’t fret. With the addition of a few late-blooming flowering plants, your containers can look fresh and seasonally appropriate. Whether you choose annuals or perennials, fall is a great time for bolder colors and textures.One caveat when purchasing a perennial for containers: It’s best to find those that are viable two USDA zones below your zone if you want the plant to return next year. Find your zone hereThis is because potted plants don’t have the insulation that in-ground plants have, and their roots may freeze. Of course, you can also just treat these perennials as annuals and move on.It’s up to you (and your budget) to decide if you pop in a few new plants or start over from scratch. The following are several autumn beauties that can last you till the first frost and even beyond. Pair them with other fall foliage plants for brilliant displays.

Pansies(the orange blooms around the rim of this front pot) are the typical go-to plant for fall, and with good reason. The pansies labeled “hardy” can withstand a frost or two and, if you’re lucky, may even come back the following spring. Plus, pansies come in more colors than you can shake a dead petunia at. Pansies are low growing, with a mounded shape, and work well as a filler in the front of your container. Their broad blooms shine when combined with ornamental grasses or finely textured asparagus fern.Botanical name: Viola x wittrockiana
USDA zones: 6 to 10
Water requirement: Medium moisture, well-drained soils
Light requirement: Full sun to light shade
Mature size: 1/2 to 3/4 foot tall and 3/4 to 1 foot wide
Aster x frikartii is another fall staple and can be found at most garden centers in late summer. Asters also stay in a somewhat mounded form, and their purplish-blue colors pair nicely with ornamental cabbage and contrast beautifully with orange- and rust-colored blooms.Botanical name: Aster x frikartii
USDA zones: 5 to 10
Water requirement: Medium moisture, well-drained soils
Light requirement: Full sun to light shade
Mature size: 1 foot to 2 feet tall and 3/4 to 1 foot wide
Coneflowers make great statement plants in containers. The ones featuring sunset-like colors are terrific in autumn. A few standouts include the varieties ‘Art’s Pride’ (shown here) and ‘Firebird’. As these can grow rather tall, you’ll want to place them in the center or back of your container. They pair well with a chartreuse Alternanthera or Carex.Botanical name: Echinacea
USDA zones: 3 to 8
Water requirement: Dry to medium moisture, well-drained soils
Light requirement: Full sun to partial shade
Mature size: 2 to 3 feet tall and 1 1/2 to 2 1/2 feet wide
Rudbeckiais another wonderful fall container choice. With its yellow-orange petals and dark brown center, it is the epitome of autumn. The aptly named ‘Autumn Colors’ variety, featured here in the center, is a short-lived perennial that is often treated as an annual. It looks nice here mixed with orange nasturtium.Botanical name: Rudbeckia
USDA zones: 3 to 8
Water requirement: Dry to medium moisture, well-drained soils
Light requirement: Full sun to light shade
Mature size: 1 foot to 2 feet tall and 3/4 to 1 foot wide
Stonecrop is a late-blooming perennial that can last well past a few frosts. Its foliage ranges from icy blue-green to dark burgundy. And its thick, fleshy leaves and flowers look great next to airy plants and grasses with a finer texture. ‘Thunderhead’ is the variety shown here and is stunning next to dainty pink blooms.Botanical name: Sedum
USDA zones: 4 to 10
Water requirement: Dry, well-drained soils
Light requirement: Full sun
Mature size: 2 to 2 1/2 feet tall and 2 feet wide
Million bellsis a showy plant that flowers almost nonstop through fall. Its wide range of color options makes it an easy choice for mixed containers. The coral-color variety in this photo would also look nice spilling out of a container filled with purple asters and dark heuchera.Botanical name: Calibrachoa
USDA zones: 9 to 11
Water requirement: Medium moisture, well-drained soils
Light requirement: Full sun to light shade
Mature size: 1/4 to 3/4 foot tall and 1/2 foot to 2 feet wide
Verbena bonariensisis a unique yet stunning plant with tall, slender stems topped with clusters of rosy lavender blossoms that attract butterflies — and, it’s deer resistant to boot! This plant is considered an annual outside of zones 7 to 10, but it may self-seed. It has been known to become invasive in the Deep South, so you will want to avoid using it in those areas.Botanical name: Verbena bonariensis

Water requirement: Medium moisture, well-drained soils
Light requirement: Full sun to partial shade
Mature size: 2 to 4 feet tall and 1 1/2 to 3 feet wide
While ornamental peppersdo flower, their glossy purple leaves and fruit are what make this plant a late-season knockout. While the peppers are technically edible, they’re extremely hot and not recommended for consumption.’Purple Flash’, seen here in the center, grows into a bushy mound approximately 18 to 24 inches tall. Pair it with Verbena bonariensis and bright lime-green creeping Jennyfor a dynamic presentation. Caution: This plant is considered invasive in a few areas of the U.S.Botanical name: Capsicum annuum
