In September, I had the opportunity to visit three public gardens: Chanticleer near Wayne, Pennsylvania; Berkshire Botanical Garden in Stockbridge, Massachusetts; and Yampa River Botanic Park in Steamboat Springs, Colorado.

What struck me was the colorful perennial flowers that were blooming in the fall. Of course, not everything that grows outside Philadelphia grows here in Cheyenne where we are two Plant Hardiness Zones colder, Zone 5.

We match the western Massachusetts mountains for zone, but they get four times our 15 inches of annual precipitation. Plus, they have acidic soils supporting those billowing mounds of hydrangeas I saw everywhere.

Even in Steamboat, only 700 feet higher in elevation, there are plants that require the protection of a thick layer of snow all winter which we don’t have.

So I decided to look around town, especially our own Cheyenne Botanic Gardens, to see what blooms late, for the benefit of bees and our own enjoyment.

Annual flowers are colorful right up to first frost, average date Sept. 20 (though in the last few years in some parts of town it may be as late as mid-October). But unless they self-seed, I can’t justify buying flats of annuals every spring to cover all my garden beds, nor have I the greenhouse to start my own. Instead I turn to perennials. Here are suggestions for you to add to your garden next spring. Or if we haven’t had a frost yet, find them on sale and plant them this fall.

2016-10-1-rudbeckia-by-barb-gorgesI’ve done well with black-eyed Susan, Rudbeckia species. Their golden yellow petals and brown centers must have inspired the University of Wyoming’s selection of school colors. There are many varieties based on native species: short or tall, diminutive or gigantic flowers, mid-summer bloomers or later. Some bloom a long time—over a month. Some are better at coming back year after year.

2016-10-2-aster-by-barb-gorges            My other success has been the fall-blooming asters, Symphyotrichum species. One variety is a 2-foot-tall shrub of lavender-colored, 1-inch flowers. It’s come back every year for over 20 years, waiting until mid-September to bloom. But another, brighter purple aster in a sunnier spot started blooming three weeks earlier and is still blooming well. Perhaps it is a newer variety bred for a longer bloom time than the native plants.

I hesitate to give you actual variety names because nurseries so often move onto the next best thing. You might as well go for what’s available rather than mourn what you can’t find. However, if you are interested in native perennials, check sources like www.alplains.com.

2016-10-3-gaillardia-by-barb-gorges            Blanket flower, Gaillardia species, is another hard-working perennial native to North America. It can start blooming in early summer. Horticulturists have had a field day designing varieties with different color patterns. A member of the aster family, it has petals that can be plain yellow, yellow with bands of red, or nearly all red-orange with a little yellow trim. Some are short, some tall. The seed heads are prickly little balls. If you deadhead them when they are finished blooming, they will put out more flowers. If you don’t, they will drop seeds that will sprout next year, like many other easy-to-grow perennials.

2016-10-4-hollyhock-by-barb-gorges            I’ve noticed that some of my summer bloomers will bloom into fall if I water them enough. I have a bed with a row of hollyhocks growing along the back. It gets watered by a sprinkler head that does a good job at one end but hardly gets water to the other end. Thus, the hollyhocks on the dry end finished blooming a month before the hollyhocks on the wet end.

2016-10-5-salvia-by-barb-gorges            Perennials that bloom in early summer may start blooming again in early fall—perhaps they don’t like hot mid-summer temperatures. I’ve had ‘Hot Pink’ Salvia, Salvia gregii, come back into bloom this year.

Microclimates make a big difference as to when perennials bloom. Nettie Eakes, assistant education director at the Cheyenne Botanic Gardens’ Paul Smith Children’s Village, said visitors are always telling her how the same flower in their yard is either behind or ahead.

The Children’s Village is lucky to be protected by high stone walls. On their north-facing sides, they provide shade and make a cool, slow-growing microclimate. On the south-facing sides, they absorb sunlight and make a warmer, faster-growing microclimate which can also extend the growing season.

2016-10-6-sneezeweed-by-barb-gorges            The most noticeable perennial I found blooming September 18 at the Children’s Village was sneezeweed, Helenium autumnale, a 6-foot-tall plant with multiple small sunflower-type flowers, each with yellow petals and ball-shaped yellow centers. Nettie said they increase by sending out underground stems, but are not very invasive. Helenium comes in many other variations and bloom times.

2016-10-7-giant-hummingbird-mint-by-barb-gorgesOver by the office door, three-foot tall giant hummingbirds mint, Agastache pallida ‘barberi’, does not have shout-out-loud color. But it is a nice contrast: silvery spikes of tiny purple flowers. And maybe it will attract a late hummingbird—or hummingbird moth.

2016-10-8-karl-foerster-grass-by-barb-gorgesAt the front entrance to the Children’s Village is ‘Karl Foerster’ feather reed grass, Calamagrostis acutiflora ‘Karl Foerster’. It’s a go-to plant for landscape designers these days, but that’s because it looks so neat. Growing around four feet tall, it starts out green in summer. Then the seed heads ripen to a golden wheat color. Finally, the whole plant turns gold. It is tough enough to stand and provide color all winter before getting cut back in spring.

2016-10-9-russian-sage-by-barb-gorgesA wispy, shrubby perennial also favored by landscape designers in our area is Russian sage, Perovskia atriplicifolia. Each branch sprouts from ground level, with silvery leaves on the lower half and small blueish lavender flowers on the upper half of each stem. It likes sunny spots and will spread.

Chatting with my Laramie County Master Gardener friends, Steve Scott and Kathy Shreve, I also have this list of fall bloomers for you to think about planting next year:

2016-10-10-autumn-crocus-by-barb-gorgesAutumn crocus, Colchicum species. Corms are planted in July or August. The blossoms are much larger than spring crocus.

Blue sage, Salvia azuria, native to central and eastern North America.

2016-10-11-goldenrod-by-barb-gorgesGoldenrod, Solidago species, blooms are branches of tiny yellow flowers. Many are native to North America.

2016-10-12-joe-pye-weed-by-barb-gorgesJoe Pye weed, Eutrochium species, another North American native, sometime varieties are 5 feet tall, with panicles of purple-pink flowers.

2016-10-17-maxmillian-sunflower-by-barb-gorgesMaxmillian sunflower, Helianthus maximiliani, native to the Great Plains, 2 to 10 feet tall, branches with many yellow flowers.

2016-10-13-purple-coneflower-by-barb-gorgesPurple coneflower, Echinacea purpurea, daisy-like, native to North America, many varieties, 1 to 4 feet tall.

Snakeweed, Gutierrezia species, a shrub with yellow flowers native to western North America.

2016-10-14-rabbitbrush-by-barb-gorgesRabbitbrush, Ericameria nauseousus, or Chrysothamnus viscidiflorus. Both are yellow-flowered shrubs. The native varieties grow on our drier prairies.

2016-10-15-autumn-joy-sedum-by-barb-gorges‘Autumn Joy’ sedum, Sedum telephium, is a stonecrop. The fleshy stems grow 1-2 feet tall, topped with bunches of tiny purple-pink blossoms. It can be found in the Cheyenne Botanic Gardens perennial bed.

2016-10-16-obediant-plant-by-barb-gorgesObedient plant, Physostegia virginiana, looks like a 2 to 4-foot-tall snapdragon with pale lavender-pink flowers. It is also at the Gardens.

Planting gardener partnerships

Published Jan. 18, 2015, in the Wyoming Tribune Eagle, “How to plant a partnership. How do gardening duos work out what to grow and who will weed and water?”

By Barb Gorges

Last year, I relinquished our small vegetable garden plot my husband, Mark, so he could experiment with all the new information he was learning as a Laramie County Master Gardener intern.

I even refrained from harvesting any cute cherry tomatoes and popping them in my mouth when I walked by.

Well, almost.

This year, I want to grow vegetables again. This has me thinking about how gardeners work as partners. How do they split decisions and the maintenance? Before I learned to grow a tomato three years ago, it was easy: Mark grew our vegetables and I grew flowers.

I’ve interviewed people from four partnerships to see how they work.

Sisters

Jennifer Wolfe and her sister, Gina John, own the house, now 100 years old, in which they grew up. Because its location is close to the Capitol, they decided to turn it into office rental space. Because the city requires a landscape design for commercial properties, their gardening decisions are based on those requirements.

Jennifer, with her master gardener training, said they decided to make providing habitat for wildlife their objective, rather than waste money on lawn watering. So she and Gina have converted the space to mostly perennial flowers, with many of the plants contributed from their home gardens. You may have seen it on the Master Gardener Garden Walk in 2013.

Because her sister is still working, Jennifer is the primary gardener. Gina comes sometimes comes in the evenings to help and seems to be in charge of adding garden art.

Employees of the tenant, a health services company, appreciate the effort, often strolling the garden and opening windows to let the garden sounds and fragrances in.

Business partners

A quick perusal of the Laramie County Master Gardeners directory shows there are 15 sets of people who share the same last name and address. Presumably they are couples in which both take a serious interest in gardening.

One of these couples, Scott and Jackie Taylor, went so far as to take the advanced master gardener training recently.

They are cultivating a serious amount of space–15,000 square feet–including two high tunnels and an orchard, plus raising livestock, west of town, near Gilchrist Elementary. You may have seen some of their harvest for sale at the Tuesday and winter farmers markets.

In business together in Laramie for 30 years previously, they have learned how to disagree, come to a decision, and still be friends.

“We start with seeds, look at plot space, and it’s invariably a big discussion and I want more than there is room for and Scott reins me in,” said Jackie.

When it comes to the chores, Scott said, “I do the fencing and digging and bed prepping. Jackie does the seedlings.”

This is a fairly typical division of labor—one person is more attuned to the details of nurturing delicate plants.

Scott is also in charge of watering, with the help of timers, “I’ve got things on a rotation in my own mind.”

But Jackie, after weeding, will report on potential moisture level problems. And while the vegetables are a joint venture, “He’s more interested in the fruit trees and I’m more interested in the flowers,” said Jackie.

They’ve been married 44 years, “going on 70,” one of them said.

Scott’s advice, “Learn to laugh. You have to resolve conflicts, like over row spacing. You have to be able to talk it out and get on.”

There is a benefit.

“It’s nice to enjoy the fruits of our labors together,” Jackie said.

Family style

Riley Elliot digs gardening.

At a young age he was using his toy truck to move dirt in his mother’s garden. Now he, at age 11, and his mom, Carolyn, are newly fledged master gardeners.

You might run into Riley at the Paul Smith Children’s Village where he volunteers. It was when he and his mom visited in 2011, shortly after moving to Cheyenne, that director Aaron Sommers began encouraging Riley’s interest in gardening.

Last year, at home, out on the prairie west of town, his dad Reagan helped Riley build raised beds out of old shipping pallets and fence the deer out.

Riley grows vegetables he promises to eat, such as peas.

“Last year, my first year gardening, I grew peanuts, popcorn and pumpkins,” he said. “Peas do real well and the popcorn did real well, and probably the peanuts (if the chickens hadn’t uprooted them while searching for grubs), but the sweet potatoes need more sand.”

He and Carolyn have big plans for this year, hoping to do better.

“We are just starting to do some flowers,” said Carolyn.

Since there wasn’t time to install the automatic watering system, Riley helped out with hauling hoses.

“We really didn’t have to weed that much,” he said, because raised beds aren’t very weedy.

While Riley believes in eating what he grows, he only wants to eat some of what’s in his mom’s vegetable patch. When the deer got her cabbage and Brussel sprouts, Carolyn said his reaction was, “I wish I could find Bambi and pat him on the head.”

 

Botanists

Jane Dorn spent years holding down the fort, garden-wise, while her husband, Robert, spent summers out in the field working as a professional botanist.

Not that he wasn’t interested in what was growing and helping with the gardening—he’d worked in his uncle’s greenhouse when he was growing up.

When Jane retired, the couple left Cheyenne and built a cozy house on acreage outside Lingle. Recently, they built a greenhouse over their vegetable patch. It has become Robert’s domain for experimenting with vegetable growing. He has begun to keep extensive records, the scientist in him unable to be suppressed.

Now, when planning this year’s garden, Jane and Robert discuss the veggies: what has done well, what seeds are left over, what new varieties in the seed catalogs sound like they might do well.

“We plant multiple varieties because some work better one year than another,” said Jane.

They also discuss Jane’s native plant prospects. “I’m trying to grow native wildflowers,” Jane said. Robert helped her build a rabbit-proof fence.

She and Robert are co-authors of “Growing Native Plants of the Rocky Mountain Area.” Jane will be speaking about growing natives at the Habitat Hero workshop March 28 sponsored by Laramie County Master Gardeners, Cheyenne Audubon and other organizations.

Discerning what the native plant catalogs are offering, whether they are new improved varieties, or just renamed originals, and whether they will grow at their homestead makes use of Jane and Robert’s lifetime of expertise.

While they have affinities for certain parts of the garden, Jane explained, “You don’t want to get yourself in a situation where one of you doesn’t know how to operate the rest.”

Both Jane and Robert weed, though with raised beds there is not much to do. While Robert has drawn up the watering schedule for the drip irrigation system, Jane can also run it. Jane seems to have a knack for harvesting beans, and Robert takes great joy in bringing greens in from the greenhouse every night for dinner–all winter long.
