Fall is here which means cool weather and frosty mornings are headed our way. Unfortunately for your plants, there’s no heater or jacket that can help keep them warm, and as a result, some of your plants will begin to look a little sad once temperatures start to drop. If you’re like many gardeners, that means it’s time to hack everything back! Well…maybe not. If you have any of these plants listed below, you’ll want to avoid cutting them to the ground later this fall, or in some cases, cutting them back at all.
- Azaleas: prune these once they’re past flower, but before the fourth of July.
- Rose of Sharon: likes to be left alone for the coming winter and instead cleaned up in the early spring.
- Lavender: Wait until March! Cut out any dead wood at the end of winter to ensure the best new flush for your lavender plants.
- Montauk Daisy: (Nipponanthemum) Cut this woody perennial back to six inches from the ground this fall, rather than all the way to the ground.
- Russian Sage: (Perovskia) If the shape or health of the plant has been compromised, cut it back aggressively this fall, to roughly six inches. If not, leave it alone until early to mid-spring, removing any dead wood and cutting back to where you see new growth emerging. Remember, it’s a late-breaking plant, so give your sage a little extra time to start growing.
- Rhododendron: like azaleas, rhododendrons can be pruned once they’re past flower, but before the fourth of July.
- Roses: like to be left alone for the coming winter, and instead cleaned up in the early spring.
- Geum: Remove any damaged or dead foliage now, but leave the majority of the plant for the winter. You can repeat this process again in April, removing any leaves with winter injury, and even divide it around April or early May, every three to four years, but if you need to cut it all the way back, wait until after it’s past flower.
- Perennial Hibiscus: cut this plant back to about six inches from the ground this fall… not because it will grow from the stump, but rather to keep a marker for you to remember you have this plant. Perennial hibiscus won’t be back in your garden until at least June!
- Summer and Fall blooming Clematis: Wait until spring to clean up any dead wood on these plants, once you start seeing a little new growth.
- Ornamental Grasses: Keep these around all winter to protect the base of the plant, where the new growth will emerge in spring. Don’t cut them back until March at the earliest, or April at the latest.
- Panicled Hydrangeas: like to be left alone for the coming winter, and cleaned up in the early spring.
- Lilacs: prune after they’re past flower, but before the fourth of July.
- Evergreens: can be pruned in mid-spring after the plants have begun to flush lush new growth.

Creeping phlox is a great rock garden plant and a great ground cover. It’s a native plant that is deer-resistant and required part to full sun.
At Van Wilgen’s, we carry four colors: white, purple, pink, and blue. What I love about this plant is how easy it is to grow. Just use a topsoil peat moss compost mix when planting it.
It’s a low-maintenance plant that can cover difficult areas of your landscape that also livens up a walkway or flowerbed edge. It’s a great early season pollinator plant as the bees are first waking up – its blooming serves as a wonderful early season nectar source.
Creeping phlox is good for erosion control and you can dig it up and split it every few years. There is no need to deadhead the flowers and as they go by you’ll have a nice, green mat for the fall.
Fertilize it in the spring and fall and you’ll have beautiful creeping phlox blooming again the following year.
Fertilize in spring and fall to have a great year the following year, plant tone.
As summer comes to an end, rustic autumn colors sweep in as the season’s vibrant blooms begin to fade. Keep your garden looking fresh this year with some fall flowering plants in your space! Utilize plants with late bloom times and apply Bloom Booster to ensure your flowers are reaching their maximum potential.
Here Are Our Top Flowering Plants That’ll Put on a Fall Show
Garden Mums
The color variety available for garden mums makes this one of our favorites for fall flowers. Mums can come in autumn hues of orange, gold, russet, and bronze which will keep your garden looking great all season long. Perennial Mums will last through the winter and will bloom again next year. Plant in full sun. Grows 18 inches tall.
Celosia
Celosia brings incredible color and vibrancy to your garden. They offer flowers in different shapes and colors from the brain like cockscomb to the showy plume varieties that produce feathery flowers that look like flames or puffs of cotton candy. They bloom until the first frost. Plant in full sun. Grows up to 3 feet tall.

Daisy-like blossoms, with a resemblance to a star, will give your garden a fresh new shade of color. Blossoms in pinks, purples, blues, and whites emerge in late August to extend the beauty. Plant in full sun. Grows 5 inches tall.
Pansies
These rounded, flat-faced flowers bring a variety of bright colors, and some autumn colors, to balance out your garden. Pansies are versatile and can be planted in your garden, a container, or planting beds. They bounce back after a bit of light frost, which does well in an autumn garden. Plant in partial to full sun. Grows 6-12 inches tall.
Montauk Daisies
This fall long-blooming daisy stands up to salt spray, heat, and tight planting conditions in a cottage garden setting. Grows about 3 feet tall.

The perennial department at Van Wilgen’s lives at an interesting crossroads. We watch as the nursery yard fills up with evergreen interest, and the Greenhouse loads up on pansies, and we poke and prod our plants, waiting for the day that they too might be in bloom. Then the evergreen gives way to the spring bloomers, and the greenhouse starts whispering about veggies and herbs, and perennials…. While, we proudly display four or five perennial plants that bloom early (here’s to you, hellebores, and columbine) and continue to wait. Until now.
The perennial season is finally in full swing, and our humble department is about to go off like the fourth of July. From catmint and salvia in full bloom to coneflowers, yarrow and coreopsis just about to break open, all our favorite plants are finally arriving on the scene. Red Hot Poker? Budded. Delphinium and Heliopsis? Buds and blooms! Bellflower and Iris and Bee Balm, oh my! It’s June- the best time of year to be a perennial gardener. Come enjoy it with us.
Here are a few of Trevor’s favorite’s that look fantastic right now!
Echinacea Lemon Yellow– Sunny, lemon yellow blooms sure to brighten a summer border! A must-have for a cutting garden, this drought-tolerant perennial was bred for cold hardiness and compact form with prolific flowering over an exceptionally long season.
Gaillardia Spin Top Yellow Touch-Each plant is bathed in big, flat, solid, medium red daisies with just a touch of yellow at the tips of each petal that blooms from late May through early July.
Geranium – Johnsons’s Blue-Large, blue-violet flowers appear continuously from spring to fall above finely cut, divided leaves. Use in borders, rock gardens, and containers.
Perovskia- Crazy Blue-A compact and colorful, easy-care perennial for use as an accent, border, or mass planting. Violet-blue flower spikes arise from the lacy, gray-green aromatic foliage, adding an airy feel to the landscape. Hardy and heat tolerant, and sturdy, interlacing branches do not fall open in wind and rain. Deer and rabbit-resistant.
Delphinium – Blue Butterfly -This little beauty stands at a height of 14″ and forms compact mounds of well-branched foliage. It puts on a spectacular show from early summer to fall, with 1.5″, deep blue flowers that cover the lacy leaves. Though it is short-lived, it is worth using as edging, a bedding plant, or in containers combined with brightly colored annuals.

There’s no doubt that hydrangeas can hold their own in the garden. With big colorful blooms and beautiful green foliage, summer’s favorite flower makes a bold statement in any garden.
But, why not pair them with delicate foliage, bold flowers, or subtle ornamental grasses for more variety? If you’re looking for ways to make your hydrangeas pop, even more, try these companion planting tips.
When planting hydrangeas, be sure to use Espoma’s Organic Soil Acidifier for best results.
Foliage
It’s hard to go wrong when choosing a color for companion plants. Try pairing hydrangeas with foliage in different hues of the same color. This adds subtle dimension and almost creates a 3-D effect in the garden.
If your hydrangeas are pink, pair them with Rose Glow Barberry shrubs. The deep pink and purple foliage emphasizes the pastel pink flowers and contrasts perfectly with the green leaves. Try planting Blue Star Juniper alongside blue hydrangeas for a beautiful display. This low-maintenance shrub provides beautiful bluish-green foliage that complements any blue flowering plants.
Flowers
When planting flowers with flowers, timing is everything. Be sure to choose a summer-blooming flower that will blossom around the same time as your hydrangea. You can choose to plant similar hues or bright contrasting colors. If you’re looking to create a dramatic contrast in the garden, choose a flower that comes in a variety of colors.
Begonias and geraniums are beautiful flowers that come in many different shades, making them a perfect companion for hydrangeas. Create a colorful rainbow garden by pairing blue hydrangeas with pink geraniums or white hydrangeas with scarlet begonias.
Grasses
If you want the focus of your garden to be mainly on hydrangeas, opt for more subtle ornamental grasses that simply enhance their beauty. Most ornamental grasses are low-maintenance and easy to grow, giving you more time to spend perfecting your hydrangeas.
Fountain grass is one of our favorites because it provides pretty feathered plumes that dance in the wind. Green and yellow Japanese forest grass also complement hydrangeas very nicely.
