Southern Gardening

I’m like most home gardeners when it comes to working in and maintaining my garden and landscape. My philosophy to garden chores can be summed up by the catchphrase of a friend of mine who is a home improvement expert: “I’m all about easy.”

This philosophy is especially true during the heat and humidity of the summer.

But despite my desire to do things the easy way, there are important summer garden activities required to keep some flowering plants looking good. Deadheading is one of these maintenance chores that often gets overlooked.

Most gardeners have favorite landscape plants they use every year, and I’m no different. But I also like to try new plants I see in garden centers or learn about from perusing winter catalogs.

This week, I want to tell you about some of the plants that are so far performing well in my landscape.

One plant I like to grow each summer is Blue Daze evolvulus, because this is an easy-to-care-for plant that needs minimal attention. Blue Daze has been around for a long time and was one of the first plants chosen as a Mississippi Medallion winner in 1996.

Our gardens and landscapes are heating up, and for hot summer color, you just can’t beat the annual vinca.

In my opinion, vinca is one of those perfect landscape plants. It produces loads of color and handles the high heat and dry conditions of our Mississippi summers.

Some of the very best vinca plantings I have seen were growing in raised beds. But in some years, entire planting beds of vincas seemed to fail almost overnight. A common characteristic of these failures is wet soil. Vinca plants do not like to grow with their feet wet.

Tropical plants, like elephant ears, just scream for attention and attract interest in any landscape. Most gardeners love elephant ears because they are easy-to-grow tropical plants that make a big impact.

There are three species commonly found in Mississippi landscapes: Alocasia, Colocasia and Xanthosoma. Colocasia is my favorite elephant ear variety and the focus of this column. Most Colocasia plants feature big leaves and big texture, but they’re not all green. In fact, there are Colocasia varieties with black leaves.

With all of the annual flowering plants being displayed in garden centers, you might be distracted and pass right by the gorgeous foliage colors of caladium. And this makes the caladiums feel bad.

Caladiums are among the most misunderstood plants in landscapes and gardens. Do you plant them in the sun, shade or some kind of mixed sun and shade? The answer will be revealed later.

Foxglove can create a dramatic effect with its tall spires of flowers but is an underused plant in Mississippi, especially in the southern counties.

Foxglove, known botanically as Digitalis, is a member of a somewhat curious group of plants called biennials. These plants typically take two years to complete their lifecycles. After germination, the plants only grow vegetatively (leaves, stems and roots), usually forming a low-growing rosette.

Many seasoned gardeners, myself included, consider Angelonia one of the best plants for the hot summer garden.

Angelonia, a member of the snapdragon family, is actually called summer snapdragon. It thrives in the full sun during the heat and humidity of summer. Since this describes our usual summer weather, tolerance to these conditions is a requirement for our Mississippi gardens and landscapes.

The garden world is dominated by plants with round flowers, so the spiky texture of the Angelonia flower stalks is a welcome addition to any summer garden.

If you’re looking for something for your landscape that you’ve never tried, may I suggest flowering vines. Many gardeners enjoy these plants but don’t really give them enough attention except when they’re blooming in the spring.

Two of my favorite flowering vines are yellow jasmine and Confederate jasmine.

If there's one area in almost everyone's landscape that causes a lot of problems, it's that area between the sidewalk and the street.

I surrounded my mailbox with a small planting bed to help me try to garden in this area. I have had some success trying many different planting combinations that change with the seasons. But it is the summer that causes me the most trouble.

Home gardeners are showing more interest in planting native plants in the landscape. This makes a lot of sense because native plants have a greater tolerance to local environmental conditions. What holds them back is the fact that many have a limited ability to create excitement in the landscape.

One that defies that stereotype is the butterfly weed. This native plant was chosen as a Mississippi Medallion winner in 2012, an award given to plants selected for their superior and outstanding garden and landscape performance.

Even though we’re still early in spring, we need to get ready for the sweltering temperatures we know are on the way. This means we have to start planting two of my favorite summer plants that pack a powerful punch of summer color: SunPatiens and sun coleus.

SunPatiens love growing in full sun during the hottest parts of summer. SunPatiens are an improvement of New Guinea-type impatiens that can be grown in full sun. They have beautiful variegations and bloom from the time they are planted in late April or May through the fall.

There’s been a lot of attention paid to the matter of pruning, especially with the crime against horticulture known as “crape murder.” But we’re also in early spring, when many gardeners want to tidy up their landscape plants, and I’m no different.

This weekend, I removed a couple of large, overgrown junipers that the previous homeowner had planted. Feeling invigorated and empowered, I proceeded to prune back the small Indian hawthorn hedge along my front walk. And this is a warning to my foundation planting of boxwoods: You’re next.

In my travels visiting garden centers and greenhouses, I’ve been reminded of plants that we don’t grow enough in Mississippi. Dahlias are on that list.

I can’t decide if it’s because gardeners think these beautiful plants need an extraordinary amount of care or they’re just not aware of them, but we need to grow more dahlias.

Dahlias grow from bulb-like structures that resemble sweet potato tubers. They are easy to grow, and if you can grow tomatoes, you can grow dahlias.

After living in the North, I miss some of my favorite spring and summer plants as I now live in coastal Mississippi. Columbine is one I miss, as I love the way the flowers seem to be suspended in midair by the slender stems as if floating on a gentle breeze.

In my opinion, you need a columbine regardless of where you garden. Columbine can grow in Mississippi if you treat it as an annual because of our shortish springs and long, hot summers.

I enjoyed the warm spring weather while driving around south Mississippi this past weekend. One of the sights I noticed for the first time this year was the wisteria starting to bloom.

Wisteria doesn’t bloom at the first sign of warm weather. It’s one of those plants that waits patiently and is a good indicator that spring has officially sprung.

I’m always amazed at how high wisteria can climb into the tops of the trees, showing off how vigorous and aggressive these plants can be. As such, they can seem to be a little too much for the typical home landscape.

It seems that crape myrtles face a lot of dangers this time of year.

Many still face “crape murder,” or being butchered by having their branches improperly cut off at the same place every year. A novice gardener sees a so-called “professional” landscape company do it, so they think they need to cut their own crape myrtles in the same way. In horticulture CSI terms, this is a classic copycat crime.

But this column is about another threat to our beautiful crape myrtles.

Mother Nature has been teasing gardeners lately as the weather flips back and forth from warm, early-spring days to freezing temperatures and winter precipitation. I want summer to arrive!

This weekend kicked off the spring gardening season with the Garden Extravaganza in Biloxi. What a relief it was to browse the booths, checking out the latest in spring garden and landscape offerings and speaking with growers. I enjoyed the change from flipping through the big stack of garden catalogs and binge watching home and garden TV shows.

Through the column and television show “Southern Gardening,” I have the chance to share some of my favorite landscape plants with home gardeners all across Mississippi. And believe me, I have a lot of favorite plants depending on the season, flower color and more.

This week as I’m getting ready for summer, I’m thinking hard about purple coneflower, known botanically as Echinacea.

This past weekend really had me thinking about gardening and landscaping. It was an unseasonal 79 according the thermometer at my house, and I started to putter around the yard, trying to decide what needed to be done to get ready for spring.

Of course, I made a trip to see what plants were on the benches at the local garden center. But by afternoon, I had come to my senses. According to the weather forecasted for this week in much of Mississippi, we haven’t seen the last of winter.

With the cold winter weather upon us, are you thinking about planting annual color for the summer? It’s never too early to plan ahead, and thinking about the beautiful landscape you’ll have in the summer is one way to enjoy the dreary winter months.

One of the reliable summer-color plants I like the most is the petunia, and in my opinion, you can’t go wrong with Supertunias. Their selection of colors allows you to work with any color scheme.
