Fall is the season of change. The verdant green of the prairie melts to lifeless, barren forms – a stark contrast to the landscape that once looked so alive. But for now, as change happens, we are blessed to partake in hues and colors of striking beauty. Trees explode with vibrant shades of orange, red and yellow. Native grasses develop vivid colors and attractive blooms. Asters, goldenrods and sunflowers speckle the horizon. It is the crescendo of the whole year.

Maybe you have noticed these dramatic changes happening, too. Plants that once blended into their surroundings are suddenly visible. It’s as if someone turned a light on them. Even the prairies and roadsides display beautiful shades of gold, purple, apricot, olive, and copper with autumn wildflowers, shrubs, and curling, rustling grasses. Here are a few that I have seen lately along the roadsides of south-central Kansas.

Sumac

There is no other shrub that signals fall more than sumac. The blood red leaves and clusters of seeds are striking. They are like beacons along the roadsides. If only we could advertise with these shrubs, because they catch my eye every time.

Dogbane

This close relative of milkweed has so much going for it. Dogbane is host for many insects. In fact, the US Department of Agriculture Natural Resources Conservation Service (USDA NRCS) ranks Dogbane’s value to pollinators as ‘very high’. Dogbane typically grows two to three feet tall and develops into larger colonies. Right now, they are a bright yellow, which makes them stand out even more. Even the common milkweeds have turned a nice golden color.

Big bluestem

The “King of Grasses” is big and bold. The reddish purple stems begin to change and set the landscape ablaze with their intense colors. Look for the distinctive “Turkey Foot” seed head, too.

“I took a long walk north of the town, out into the pastures where the land was so rough that it had never been ploughed up, and the long red grass of early times still grew shaggy over the draws and hillocks. Out there I felt at home again.” -Willa Cather, My Antonia

Switchgrass

There are a number of outstanding native grasses that provide late season interest, but Switchgrass Panicum virgatum is one of the more common grasses in roadside ditches. It grows to a height of 3-6 feet and turns orange, yellow and fiery red-tipped shades in the fall. The persistent airy blooms and attractive fall colors make this an attractive grass in the landscape.

Osage orange

This tree is along many roadsides in south central Kansas. It is still incredible to see those huge hedge apples dangling from the branches and scattered on the road. The tough demeanor of this tree including its thorns made it ideal as a living fence. Many were planted during the Dust Bowl days as part of WPA projects to prevent soil erosion in the Great Plains states.

Heath aster

Asters are the grand finale to the prairie garden. Heath asters are one of the last asters to bloom. The diminutive white flowers cover the entire plant, making them look like snow mounds in the prairie. They are one of the last great feeding opportunities for bees, butterflies, and other pollinators before they migrate or go dormant for the winter.

Although each season is different, autumn is a very special time. Life has come full circle, from spring through summer and ultimately ending in the fall. It is the perfect time to enjoy all that is changing around us. It is a time to take in sights, sounds and smells of the prairie and connect anew with the natural world.

Bonus Plant: Pink smartweed

Pink smartweed is prolific, growing wild in nearly every roadside ditch. The bright pink flowers and red stems are very striking. They thrive in damp or wet sites, but it is an annual. If you want some for your landscape, collect the seed after the pink flowers fade.

It is so common around this part of the country that we take it for granted, but the Osage Orange (Maclura pomifera) is a very special tree, valuable to both farmer and wildlife, and integral to the agricultural history of Kansas.

Osage Orange, of course, is the tough, thorny tree of Central Kansas hedgerows. To many people, it’s also known as hedgeapple, or simply hedge. It grows so well here, even escaping out into fields and wood lots, it seems that it must have been here before the pioneers arrived.

Osage Orange Hedge

Actually, Osage Orange did not occur naturally in Kansas: its original range was limited to parts of Texas, Oklahoma, Arkansas and Louisiana until it was brought in for windbreaks and living fences in the 1880s. At that time, many miles of hedge were constructed by planting thousands of young Osage Orange trees closely together in a line. Many hedgerows still can be seen dividing fields and pastures today.

Once established, the thorny young trees were pruned to promote thick, bushy growth. The term “Horse high, bull strong and hog tight”, used to describe the Osage Orange, simply means that the hedge rows were pruned so that they were tall enough that a horse would not jump it, stout enough that a bull would not push through it and woven so tightly that even a hog could not find its way through. Hedge is tough!

Hedge thorns

When barbed wire was invented, the hedge fences were torn down or left to grow on their own as shelterbelts, field borders and windbreaks. Along with its attributes as a hedge, Osage Orange has long been valued for the strength and durability of its wood. Ironically, barbed wire is usually tied to a hedge post to make pasture fences.

The Osage Indians, from which the tree’s name is derived, were noted for using the wood to make bows. It is reported that Osage Orange bows were so highly regarded by Indian tribes to the north that they were willing to offer a horse and blanket in trade for one.

Anyone who has ever been around the trees in the fall is familiar with their “oranges” (or “apples”). These softball size fruit are produced on the “female” trees, while “male” trees have only pollen producing flowers and do not bear fruit.

Available Osage Orange (Maclura pomifera) cultivars include ‘Wichita’ and ‘Whiteshield’ (vase-shaped). Use fruitless and thornless cultivars only.

Hedgeapples

This common tree is often overlooked, but is a valuable and iconic component of our Kansas landscape. The resilient Osage Orange holds the soil well, and provides cover for wildlife and a windbreak against strong winds. Though it may not function as a fence for modern farmers, its presence here reminds us of the ingenuity and tenacity of our farming ancestors on the Great Plains.
