15+ perennial flowers to plant in fall

Looking for some lovely perennial flowers to plant in fall? You’re in luck!

Most herbaceous perennial flowering plants do very well when planted in the fall when the soil is warm and nighttime temperatures cool down a bit. Fall planting allows roots to become established in the soil before winter, giving the plants a head start next growing season.

Let’s see some of the best perennials to plant in autumn!

1. Peony

Peonies are renowned for their large, ruffled blossoms, which can range in color from the purest whites to romantic pinks, deep reds, corals, and even yellows in certain varieties. The blossoms can take on several forms, from simple, single petals to intricate layers of double blooms. Beyond their flowers, peonies have a sturdy, bushy growth habit, with glossy, deep green leaves that provide a beautiful backdrop in garden beds into the summer season.

Peonies are adaptable but have particular preferences. They thrive best in well-draining soil, enriched with organic matter, and positioned in a spot that receives full sun to light afternoon shade. While peonies are drought-tolerant once established, they benefit from regular watering during their initial growth and flowering phases. One unique aspect of peonies is their longevity; with proper care, these plants can grace a garden for decades, if not generations.

Planting peonies requires a bit of foresight, as their tuberous roots are sensitive to planting depth. The eyes of the tuber (small, bud-like points) should be positioned no more than 1-2 inches below the soil surface in colder climates and just at or slightly above the surface in warmer zones. Dig a generous hole approximately twice the width of the tuber, and enrich the soil with compost. After positioning the tuber, backfill with soil and water thoroughly.

It’s worth noting that peonies may take a couple of years to truly establish and produce their iconic blooms, but the wait is undeniably worth it. Opting to plant peonies in the fall gives them a chance to settle before winter, ensuring a robust start in the subsequent spring and increasing the chances of blooms in the coming seasons.

Fall asters in bloom

2. Aster

Asters stand as the heralds of the autumn garden, offering a colorful respite as many other blooms start to fade. Characterized by their daisy-like appearance, Asters feature a central disc that can be yellow, gold, or even reddish, surrounded by slender petals in shades that range from vibrant purples and blues to pinks, whites, and occasionally reds. Depending on the species and variety, the height of Asters can vary dramatically, with some dwarf varieties standing only 8 inches tall, while taller species can soar to 4 feet or more.

These perennial favorites flourish in well-drained soil under full sun, although they can tolerate some light afternoon shade, especially in areas with intense summer heat. Asters are relatively undemanding, but they appreciate moderately fertile soil that remains consistently moist. While they are somewhat drought-tolerant once established, they’ll look their best with regular watering during prolonged dry spells. Additionally, Asters are cold-hardy and can resist the early frosts of fall, making their blooms one of the last colorful displays in many gardens.

Planting Asters involves selecting a spot that gets abundant sunlight throughout the day. The planting hole should be roughly twice the size of the root ball to ensure the roots can spread out. Once positioned, the plant’s base should sit level with the soil surface. After backfilling with soil, generous watering is essential to help the plant settle in. Mulching around Asters can assist in retaining soil moisture and suppressing weeds.

Choosing to plant Asters in the fall can be particularly strategic, as it allows the plants to establish their roots in the cooler weather, preparing them for a strong start in the following spring. This root development ensures the plant is robust and ready to produce its iconic blooms by the time autumn rolls around again.

When planting perennials in the fall, make sure to water them well until the ground freezes, and consider mulching around them to protect the roots from extreme cold and to conserve soil moisture.
