Perennials That Keep the Garden Going Into Fall

By September, many summer gardens are starting to lose some of their color, but that does not mean the season is over. In fact, some of the most reliable perennials for southeastern Massachusetts are just reaching their stride.

At Wyman’s Garden Center in Hanson, fall-blooming perennials can help refresh tired beds, add late-season color, and provide valuable food for bees and butterflies before colder weather arrives. They are also excellent choices for fall planting, when cooler air and warm soil create good conditions for root development.

Rudbeckia: Reliable Late-Season Color

Rudbeckia, commonly known as black-eyed Susan, is one of the most dependable plants for carrying color from late summer into fall.

Its golden-yellow flowers stand out in perennial beds and pair well with ornamental grasses, sedum, and purple-flowering plants. Rudbeckia is also well suited to sunny South Shore gardens and attracts pollinators while in bloom.

Plant it in groups for a stronger visual impact, or use it as a transition plant between summer flowers and fall color.

Sedum: Color, Texture, and Pollinator Value

Fall-blooming sedum is another strong performer for September gardens.

Its thick foliage provides texture throughout the growing season, while broad flower clusters develop richer pink, rose, and bronze tones as fall progresses. Bees and other pollinators are especially attracted to sedum flowers during the late season, when fewer plants are blooming.

Sedum works especially well in sunny, well-drained locations and is a good choice for gardeners looking for a relatively low-maintenance perennial.

Asters Bring the Garden Into Fall

Asters provide the purple, blue, pink, and white tones that pair naturally with traditional fall colors.

They can be especially useful in mixed perennial borders where summer flowers have begun to fade. Their late bloom period also makes them an important nectar source for pollinators preparing for cooler weather.

For the best performance, give asters good sunlight and enough space for air circulation.

Ornamental Grasses Add More Than Flowers

Not every fall garden needs to rely on blooms.

Ornamental grasses bring movement, height, and texture to the landscape. Their seed heads often become more attractive as the season progresses and can remain standing well into winter.

Grasses also combine well with mums, asters, sedum, and other fall perennials, making them useful for creating a more layered and natural-looking landscape.

Don’t Overlook Foliage

Heuchera and other foliage-focused perennials can help fill gaps where flowers are no longer at their peak.

Leaves in burgundy, bronze, green, caramel, and purple shades can provide lasting color without depending on blooms. Foliage plants are particularly useful around shrubs, along pathways, and in mixed beds where they add contrast and texture.

September Is Still a Good Time to Plant

For gardens around Hanson and much of the South Shore, September can be an excellent month to add perennials.

Cooler temperatures reduce heat stress, while the soil remains warm enough to support root growth. Plants installed now have time to begin establishing before winter and are often ready to grow strongly when spring returns.

The most important step after planting is consistent watering. Even when the weather feels cooler, newly planted perennials still need moisture while their roots become established.

Build a Garden That Lasts Beyond Summer

A good fall garden is not just about adding a few mums. Combining late-blooming perennials, ornamental grasses, and colorful foliage can keep the landscape interesting for weeks longer.

Stop by Wyman’s Garden Center to see what is looking best now and ask the team which perennials are a good fit for your sun conditions, soil, and landscape.

Fall Perennial FAQ

Is September too late to plant perennials?
No. Early fall is often one of the best times to plant many hardy perennials in southeastern Massachusetts.

Which perennials are good for fall color?
Rudbeckia, sedum, asters, ornamental grasses, and foliage plants such as heuchera are all strong choices.

Do fall-planted perennials need fertilizer?
The main priority is usually good soil preparation and consistent watering. Avoid pushing excessive new top growth late in the season.

Should I cut back perennials as soon as they finish blooming?
Not always. Many seed heads provide winter interest and food for birds, so some plants can be left standing until later in fall or even spring.
