10 Perennials to Cut Back in Fall & 10 You Shouldn't


As the fall season approaches, many gardeners are preparing to tidy up their gardens and cut back their perennials. However, not all perennials should be pruned during this time. Some plants benefit from leaving their foliage intact over the winter months. In this article, we will discuss the perennials you should avoid cutting back in the fall and the reasons behind it.

Why Shouldn’t You Cut Back These Perennials?

Leaving certain perennials unpruned in the fall can provide numerous benefits. The foliage of these plants acts as a protective layer, shielding the roots from extreme temperatures and providing insulation. Additionally, the dried flower heads and seed pods can provide food and shelter for birds and other wildlife during the colder months. By avoiding pruning, you can enhance the winter interest of your garden and create a more sustainable environment for local wildlife.

1. Echinacea (Coneflower)

Echinacea is a popular perennial known for its vibrant flowers and medicinal properties. Leaving the flower heads intact throughout the winter not only adds visual interest to your garden but also provides a food source for birds. Additionally, the dried seed heads can self-sow, leading to new plants in the spring.

2. Sedum (Stonecrop)

Sedums are low-maintenance perennials that are highly valued for their drought tolerance and attractive foliage. Many varieties, such as ‘Autumn Joy,’ have flower heads that turn a rusty red color in the fall. These dried flower heads not only provide winter interest but also serve as a food source for birds.

3. Ornamental Grasses

Ornamental grasses, such as Miscanthus and Panicum, add texture and movement to the garden. Leaving the grasses unpruned in the fall not only provides winter interest but also protects the crowns from harsh winter conditions. The dried foliage also provides shelter for beneficial insects.

4. Rudbeckia (Black-Eyed Susan)

Rudbeckia is a cheerful perennial with bright yellow flowers that bloom well into the fall season. The dried flower heads provide food for birds and add visual interest to the winter garden. By leaving them unpruned, you can enjoy their beauty throughout the colder months.

5. Monarda (Bee Balm)

Monarda is a fragrant perennial loved by pollinators. The dried flower heads of this plant can be left standing in the winter to provide food for birds and add architectural interest to the garden. The seed heads can also be collected and used for propagation in the spring.

6. Hellebores (Lenten Rose)

Hellebores are early-blooming perennials that brighten up the garden during late winter and early spring. While they may not have showy flower heads, their evergreen foliage provides a lush backdrop for the winter garden. Leaving the foliage intact helps protect the plant from frost damage.

7. Heuchera (Coral Bells)

Heuchera is a versatile perennial prized for its colorful foliage. Although it may lose some of its vibrancy during the winter, leaving the foliage intact helps protect the crown of the plant. This ensures the plant’s survival and allows it to regrow in the spring.

8. Peonies

Peonies are beloved for their large, fragrant flowers that bloom in late spring. It is important not to cut back the foliage of peonies in the fall, as it helps nourish the plant and prepare it for the following year’s blooms. Cutting back the foliage too early can weaken the plant and result in fewer flowers.

9. Hostas

Hostas are shade-loving perennials known for their lush foliage. Leaving the foliage on hostas throughout the winter helps protect the crown of the plant from freezing temperatures. The dried leaves can also provide a layer of insulation for the roots.


While it may be tempting to cut back all your perennials in the fall, some plants benefit from leaving their foliage intact. By not pruning certain perennials, you can provide winter interest, food sources for birds, and protection for the plants themselves. Consider incorporating these perennials into your garden and enjoy a beautiful and sustainable landscape throughout the colder months.
