Southern Gardening

When the cooler months arrive, many home gardeners think it is time to put away thoughts of fresh vegetables on the table and settle for the local grocery store’s offerings. If this describes you, I hope to change your mind by giving you tips on growing fresh lettuce during the winter months.

The cool months of winter are the perfect time to grow lettuce as it can tolerate frost and light freezing temperatures. It doesn’t get bitter from the heat of summer. You don’t even have to grow it in your normal vegetable garden.

Some of my favorite spring flowers are annual and perennial dianthus, with their wide variety of pinks, whites, and purples, but you don’t have to wait for warmer temperatures to enjoy colorful dianthus.

Annual landscape dianthus hybrids, such as Telstar dianthus, will add color and interest to your landscape right through fall and winter.

When you consider that violas tolerate winter weather and can thrive in both the landscape and containers, it is no wonder they are a favorite bedding plant for Mississippi gardeners.

The viola, which is related to the pansy, will grow from Thanksgiving to Easter and beyond. In fact, violas are often more hardy than pansies.

Violas are known botanically as Viola cornuta but are commonly called Johnny Jump Ups. They are prolific seed producers, and it is quite common for viola to act as a perennial in the home garden.

Winter is right around the corner, and many Mississippians are starting to put their gardens to bed, waiting for the warm days of early spring. But just because it is getting colder doesn’t mean we must have drab landscapes. Now is the perfect time to put some winter color in gardens, and I’m not talking about ornamental cabbage and kale.

I am sure you have seen brightly colored pansies while visiting your favorite garden center, and those pansies are a great way to add color to your winter garden. They are tough, cold tolerant, and flower almost nonstop.

Gardening is consistently listed as one of this country’s most popular hobbies and can give joy and satisfaction to the gardener in return for the work involved. But gardening can be frustrating for gardeners who have physical limitations.

Today, gardeners with mobility issues have more alternatives and tools than ever before, and their options increase every day. The Fall Flower and Garden Fest at the Mississippi State University Truck Crops Branch Station in Crystal Springs this past weekend featured an exhibit that highlighted ways to make the garden more accessible.

The 2010 Mississippi Medallion Award Winners are Fireworks Gomphrena, Electric Lime Coleus, Purple Flash pepper and Gulf Coast muhly grass. Mississippi Medallion Award Winners are selected each year based on their ability to thrive in Mississippi’s hot, humid summers and cool winters.

The changing season and cooler temperatures make now the perfect time to decorate the front porch with a fall harvest display. These displays are ideal for Halloween and add charm through the season.

Remember to use more than just pumpkins in your display. Pumpkins are a member of the cucurbit family, which also includes squashes and gourds. Pumpkins can be orange, red, yellow, white, blue, or striped. They can be miniature, flattened, necked, smooth, winged or warty.

The Fall Flower and Garden Festival at Mississippi State University’s Truck Crops Experiment Station in Crystal Springs is one of the best horticulture field days in the Southeast. Come Oct.15 and 16 for free fun for the entire family. There will be a lot to see for everyone from garden novices to Master Gardeners.

The 3-acre garden site will showcase a great selection of tough roses, ornamental grasses like the native Gulf Coast muhly grass, tropical plants, and fall vegetables and herbs.

I firmly believe that many of our flowering landscape plants are only a step or two away from being weeds growing in a ditch. But goldenrod is an exception. Can you believe some gardeners are intentionally growing goldenrod?

Most folks recognize goldenrod growing wild when they see the explosion of golden color late in the summer, just before the temperatures start to decrease in the fall.

A garden itself is a form of personal expression, so what better way to say something about yourself than with garden art?

When we think of a garden, we often think of flowering annuals and perennials, foundation shrubs like hollies and Indian hawthorns, and small ornamental trees. But add a sculpture or homemade piece of art, and you start to bridge the gap between the gardener and the garden.

After reading about ornamental vegetables several years ago, I became interested in expanding the selection of ornamental bedding plants in my landscape. Then I saw a planting of ornamental peppers.

I am a true “chili head” with a passion for hot peppers, and I have even made an apple and habanero wine. I have grown jalapeño, habanero and the like as bedding plants, as many of the extremely hot peppers produce very colorful fruit.

It may be early September, but now is a good time to start thinking about growing fresh herbs to harvest during the winter months.

Fresh herbs are relatively easy to grow in containers. In addition to offering a feast for the palate, herbs can offer a feast for the eyes. Many of the basic herb species are available in variegated or multicolored foliage. The multicolored ones work well in recipes, but they also make flavorful garnishes.

We all know annuals such as petunia or million bells are great container garden plants, but have you ever tried including perennials in container gardens? This important group of plants can and should be an ingredient in every container recipe.

Many gardeners have a strict mindset about using annuals and perennials in container gardens: annuals are annuals and perennials are perennials, and never the twain shall meet. But if you base all your buying decisions on whether a plant will come back the next year, you will miss out on some beautiful flowers and foliage.

Liriope is an old standard when the Mississippi landscape calls for a groundcover. It is reliable in both full sun or shade, and as long as the soil is well drained, liriope will thrive in heat and drought.

Liriope is commonly known as monkeygrass or lilyturf. It is a versatile groundcover, effective under large trees where sunlight is limited or mass planted on slopes. It also creates soft borders for paved areas and foundations.

When we hear the word “daisy,” most of us think of the flower with white petals and a yellow center that we used as children to play the “loves me, loves me not” game.

Growing the Shasta daisy in your garden can bring back some of those old memories. Known botanically as Leucanthemum x superbum, Shasta daisy is a classic garden plant that is as at home in the modern landscape as it is in the cottage garden. It really shines in the garden.

I spent last week in Palm Desert, Calif., where the daily temperatures were 110 degrees or more and the humidity was less than 20 percent.

The landscapes I saw there are completely foreign to our lush, green gardens. Yet the landscape was quite beautiful, not bleak as I had imagined. There were lots of flowering desert plants, and I quickly realized that one of the first things I needed to get was a desert plant guide.

As we enter the most active part of hurricane season, now is a good time to think about ways to help landscape trees recover from storm damage.

A common myth is that the root system mirrors the top growth of a tree. While some trees do put down deep roots, most of a tree’s root system is in the top 12 to 14 inches of soil. Roots need to be near the surface to exchange carbon dioxide and oxygen gases and to ensure healthy root and tree growth. These roots also help stabilize the tree. You can see their presence and arrangement in trees that have been blown over.

Deadheading is an important garden maintenance activity, but many gardeners overlook the importance of removing spent flowers.

We deadhead flowering plants to extend the bloom period, to remove the seed source of species that could become weedy and to maintain the health of flowering garden plants.

What relative of the morning glory makes an ornamental ground cover featuring beautiful, colorful foliage?

If your answer is ornamental sweet potatoes, then you are right. Ornamental sweet potatoes, known botanically as Ipomoea batatas, are actual sweet potatoes selected for their vivid and attractive leaves. The plants produce a flower that resembles a morning glory but is hidden by the foliage. They also produce edible tubers.

Gardeners who want color in the landscape usually concentrate their efforts on flowering annuals and perennials, often overlooking plants with colorful foliage like caladiums, striped cannas or gingers.

But plants with colorful foliage can be used instead of flowering bedding plants or even in the shrub border. They have always been popular with some gardeners, but there seems to be a growing interest in these colorful foliage plants.
