Plants Need Their Rest Too
by Garry V. McDonald

This is about the time of year I start getting inquiries from local media about why leaves turn colors in the fall. What they really want to know is the exact week of peak color to inform the leaf-peepers. I usually respond that the plants are preparing to enter dormancy and peak color depends on prevailing weather conditions and is often unpredictable.

But what exactly is dormancy and why is it crucial to plants? Like explaining why leaves change color, the answer is not straightforward and “depends,” which is not the answer most people want to hear. I’ll attempt to explain in layman’s terms an interesting facet of a plant’s life.

Growing Succulents in Containers
by Jean Starr

They can be hairy, tiny, fuzzy, striped or ghost-like. They can form rosettes of dusty slate blue, green or white edged in red, or blend in with their surroundings. These are just a few of the variations found in plants beneath the umbrella term “succulent.” They’re fairly new on the mainstream gardening scene, especially in the Midwest.   >> read article

Tropical Plants
by Jean Starr

“Go big or stay at home.” It’s become one of my springtime battle cries. Like me, my garden is becoming mature, (perhaps overgrown?), with plants becoming more relaxed, settled in and, some may even say, sloppy. It cries out for some eye-catching eye candy, something with a stately presence.

Luckily, Midwest garden centers finally are embracing the beauty of the tropics, so big plants are not hard to find. And I’m not talking about hardy shrubbery. Elephant ears, papyrus and tiger-striped cannas beckon and find rides in my cart along with the premium annuals and promising perennials.   >> read article

Aprils Remembered
by Troy B. Marden

As I was scanning my photo library, considering the many garden plants I could write about for this article, I came across a file of photos, all taken during the month of April – not all in the same year, but all in April – gardens ranging from Jackson, Miss., to Louisville, Ky. It reminded me just how abundant the garden is this time of year. This is the season when gardening seems effortless. Well, almost. The weeds are as high-spirited as the annuals and perennials, so diligence in their control is necessary; but still, the garden is lush and growing rapidly, and the vibrant green of spring radiates from its very heart. There is a certain pristine quality about all of the plants emerging fresh and new.   >> read article

Dahlias for Smiles, Not for Show
You don’t have to be ‘serious’ to grow dahlias
by Caleb Melchior

My grandfather’s neighbor grew dahlias – giant things, with huge, coarse leaves. Their stems were trussed to stout bamboo poles, held captive to protect the hope of a flower. He’d pinch out most of the flower buds, trampling them into the ground, squeezing the plant’s energy into one tremendous effort of bloom. I don't grow these dahlias.   >> read article

A Wonderland of Color
Add some color to that bland winter landscape
by Stephanie Knipper

Adding color to your garden in winter can be a challenge. For many gardeners, barren beds are something we learn to live with until spring. After all, our winters can be harsh with temperatures frequently dipping below freezing. Most flowering plants do not survive in these conditions. However, there are some that flourish, and even thrive, in cooler temperatures. Brightening a winter garden doesn’t have to be difficult, you just need to pick the right plants for your conditions.   >> read article

Everything About Azaleas
by Donald W. Hyatt

Azaleas are more than a harbinger of spring. All across the Southeast, masses of red, white, pink and purple azaleas boldly proclaim that the season has arrived. Many people think azaleas come in just four colors, and some may even criticize their use as commonplace. Discriminating gardeners know better. This article cannot possibly discuss everything about azaleas, but it may foster an appreciation for their amazing diversity while providing some practical advice.

All azaleas are really rhododendrons, and fall into two general categories: evergreen or deciduous. Evergreen azaleas are very common in American gardens but they are not native plants. They all originated in western Asia, primarily Japan and China. North America is home to 17 native azalea species and they are all deciduous shrubs. Surprisingly, most are native to the Southeast! Admired in Europe since the 1800s, they have been woefully underrepresented in our gardens.   >> read article
