Welcome to the vibrant world of fall gardening! Fall isn’t just a time to admire the changing leaves; it’s also an ideal season to plant perennials that will establish robust roots in the cool, moist soil, ready to burst into life come spring.
Planting perennials in the autumn offers them a head start, as the soil is still warm enough to encourage root growth but cool enough to reduce stress on new plantings. This strategic timing ensures that your garden will be a riot of color and life as soon as winter thaws.
In this guide, we’ll explore twelve perfect perennials to plant this autumn that promise to enrich your garden with color, texture, and life.
1. Peonies
Peonies are long-lived perennials that prefer to be planted or transplanted in the fall. They bloom in late spring and offer large, fragrant flowers in a range of colors from white and pink to deep red.
Plant peony roots with the eyes (small red buds) pointing upwards, about two inches below the soil surface. Choose a sunny spot with well-draining soil that’s rich in organic matter.
Once planted, peonies can thrive for decades without needing to be moved, though they appreciate a top dressing of compost each fall to fuel their spring growth.
2. Chrysanthemums
Often known as the queen of the fall garden, chrysanthemums (or mums) are famed for their vibrant blooms.
When selecting mums, opt for hardy varieties known to survive winters, distinguishing them from their greenhouse-grown counterparts often sold as annuals. Plant them in full sun and well-draining soil, incorporating organic matter to nourish the plants.
Water regularly to establish roots before the freeze and mulch around the base to provide extra insulation against cold temperatures.
3. Sedum (Stonecrop)
Sedum, or stonecrop, is celebrated for its drought tolerance and succulent leaves, which add texture to any garden.
These plants are particularly effective in rock gardens or borders and require little care once established. Plant sedum in a location that receives full sun, in sandy, well-draining soil.
The plants should be set at the same depth they were growing at previously and spaced according to the variety’s spread.
Sedum is hardy and will return year after year with minimal intervention, making it a perfect low-maintenance choice for fall planting.
4. Asters
Asters are a must-have in any fall garden, offering a delightful splash of color late into the gardening season.
These daisy-like flowers come in shades of blue, purple, pink, and white and are known for their ability to attract butterflies. When planting asters, choose a spot that receives full sun to partial shade and has well-draining soil.
Plant them at the same depth they were in their nursery pot but space them about 1 to 1.5 feet apart to give each plant enough room to mature.
Asters are perennial in zones 4 through 8 and will thrive with minimal care, though deadheading the spent blooms can encourage a more prolific display.
5. Hostas
Hostas are the backbone of many shade gardens, appreciated for their lush foliage that comes in various shades and patterns.
These robust perennials thrive when planted in the fall, as the cooler conditions help them establish without the stress of summer heat.
Plant hostas in rich, moist soil in shaded or semi-shaded areas. Ensure the crown is set at the same level it was in the container, and space plants about three feet apart to accommodate their mature size.
Hostas require little care once established, but keeping the soil moist can help prevent the leaves from drying out and becoming crispy.
6. Echinacea (Coneflower)
Echinacea, or coneflower, is renowned for its medicinal properties and striking, daisy-like flowers that attract pollinators such as bees and butterflies.
These hardy perennials thrive when planted in the fall, allowing them to develop a strong root system over the winter.
Plant echinacea in a sunny spot with well-draining soil. They are tolerant of drought and poor soil conditions once established, making them an excellent choice for gardeners looking for low-maintenance plants.
Regular deadheading of the spent flowers can prolong blooming and encourage a denser growth the following year.
7. Daylilies
Daylilies are among the most carefree of all flowering perennials. They thrive in almost any soil, bloom profusely, and multiply over time.
Fall is an excellent time to plant daylilies because it allows them to establish a robust root system before the onset of summer heat. Plant them in a sunny to partly shaded area in well-draining soil.
Space the plants about 18 to 24 inches apart, and water them well until they are established. With minimal care, daylilies will reward you with abundant blooms year after year.
8. Rudbeckia (Black-Eyed Susan)
Rudbeckia, commonly known as Black-Eyed Susan, is a stalwart of the late summer garden, but planting them in the fall can help establish them for a stronger start next season.
These sun-loving plants are perfect for adding a pop of color with their golden-yellow blooms. Plant in full sun in moderately fertile, well-drained soil.
Rudbeckia is drought and disease resistant, making it an ideal choice for gardeners looking for low-maintenance but high-impact plants.
9. Iris
Irises add elegance to any garden with their distinctive blooms and architectural foliage. Fall planting allows the rhizomes to establish before winter, leading to vigorous spring growth and better blooms.
Plant iris rhizomes just beneath the soil surface in a sunny spot with good drainage. Ensure the rhizomes are partially exposed to the sun, which is crucial for their growth. With their variety of colors and forms, irises can be a centerpiece in the garden landscape.
10. Coral Bells (Heuchera)
Coral Bells are valued for their colorful foliage and delicate flowers that attract hummingbirds and butterflies.
They prefer a shaded or part-shaded area with fertile, well-draining soil. When planting in the fall, ensure the crown of the plant is slightly above ground level to prevent rotting.
Coral Bells are perfect for adding a splash of color to darker parts of the garden and work well in both borders and as ground cover.
11. Russian Sage
Russian Sage is a robust perennial that brings a splash of blue and an airy, delicate structure to the garden.
It thrives in full sun and well-drained soil, and its silvery foliage and lavender-blue flowers are highly drought resistant once established.
Planting Russian Sage in the fall allows it to establish a deep root system, which is essential for surviving hot, dry summers. It’s an excellent companion for other late-blooming perennials like sedum and echinacea.
12. Phlox
Fall is a great time to plant Phlox, which will provide a colorful display from early summer to fall. There are many varieties, from creeping types that make excellent ground covers to tall kinds perfect for the back of a border.
Phlox needs fertile, well-drained soil and a sunny location. Water them thoroughly after planting and apply a layer of mulch to conserve moisture and suppress weeds. Phlox is particularly susceptible to fungal diseases, so good air circulation is crucial.
Planting perennials in the fall is a proactive approach to gardening that sets the stage for a vibrant, flourishing display in the following year.
The twelve perennials listed here are just the beginning. By choosing the right plants for your garden conditions and giving them the care they need in their initial stages, you can enjoy a low-maintenance garden that thrives year after year.
Now is the perfect time to get these plants in the ground, so they wake up in your garden come spring, ready to grow and bloom.
