Garden Ideas – Les Furr’s Sunflower Screen
Veteran Master Gardener, Les Furr shares an idea he and his wife had to hide an ugly debris pile following Hurricane Michael. He planted a temporary sunflower screen to block something ugly with something beautiful. Sunflowers can be planted along a road or fence, and provide a lovely addition to your property. The seed can be saved and frozen to provide beauty to your property year after year.
Add a Pop of Color to Your Landscape with ‘Gold Mound’ Duranta
Flowers can often be fickle in the landscape, so, this year, I decided to add a shot of no-maintenance color to my landscape with foliage plants! The benefits of ornamentals that don’t need flowers to put on a show are many. Their water and fertility needs are often less because they don’t have to support the large energy and irrigation requirements the flowering process demands. They don’t need deadheading to look their best and they lend an awesome texture that is overlooked in many landscapes. My summertime foliage plant of choice provides all those things in a small, bright yellow package; it’s a widely sold selection of Duranta called ‘Gold Mound’.

‘Gold Mound’ Duranta is a small shrub known for its chartreuse to bright yellow foliage and generally grows 24” or so tall and wide in the Panhandle, allowing it to fit in nearly any landscape. ‘Gold Mound’ has been around in the horticulture trade a long time and is a popular perennial shrub in the southern parts of Florida. It was recognized as the Florida Nursery, Growers, and Landscape Association’s (FNGLA) plant of the year in 2005 and regularly occupies a spot in the color displays of big box and local nurseries, even in the Panhandle, however, despite these attributes, ‘Gold Mound’ is a rare find in Northwest Florida landscapes. That needs to change!
In our neck of the woods, Duranta ‘Gold Mound’ is incredibly low maintenance. I planted a grouping of thirteen specimens near the end of my driveway to provide a consistent season long splash of color to complement the fleeting blooms of the spring flowering shrubs, the drab greenery of the neighbor’s lawn and the on-again, off-again ‘Drift’ Roses they share the bed with. The result has been awesome! I watered frequently until the small shrubs were established and on their own, with no irrigation since. I fertilized at planting with a slow release, polymer coated fertilizer and have not had to help them along with subsequent applications. Even better, despite our frequent rainfall and heat/humidity, no pests or diseases have come knocking. Just because I enjoy gardening doesn’t mean I need a landscape full of divas and I can count on ‘Gold Mound’ to not need pampering.

Maybe my favorite part of ‘Gold Mound’ Duranta in the Panhandle is that it isn’t permanent. Duranta is a native of the Caribbean tropics and is not particularly cold hardy, most Northwest Florida winters knock it back hard, if not outright killing it. Therefore, ‘Gold Mound’ is best enjoyed here as an annual, planted when the weather warms in the spring, enjoyed until the first frost, then pulled up and discarded. Easy peasy. No long-term commitments required. My uncle, the chainsaw gardener, doesn’t even have to chop it back! Just compost the plants each winter or toss them in the trash, hit up your local nursery the next spring for some new plants and do it all over again. Though it has to be replanted each year, Duranta ‘Gold Mound’ won’t break the bank. The generic ‘Gold Mound’ is commonly sold in 4” containers for just a few dollars apiece in the annual section of plant nurseries, making it a very affordable option, especially compared to some of the new, designer perennials it competes with.
Though some landscape designers recommend just using a single specimen of ‘Gold Mound’ here and there for small pops of color, I prefer using groupings of the plant. I’ve seen successful plantings of ‘Gold Mound’ massed in large groups to create annual color beds at key points in landscapes and also planted across the front of a bed to complement darker foliaged backdrop or foundation plants, such as Boxwood or Loropetalum. Regardless of how you decide to use them in your yard, I don’t think you can go wrong with adding some color pizazz to your landscape with the inexpensive, low-maintenance, Florida-Friendly plant, ‘Gold Mound’ Duranta. Happy gardening!
Plants Can Do Unexpected Things

You never know what surprises are looming in your flower gardens.
This Rudbeckia in the photo to the left sported one bloom that was so different from all the others. The disk or central portion of the inflorescence was elongated and curved back on itself and created a contorted, crazy looking bloom. And then there was a yellow squash in my garden that had a leaf growing down the length of the squash. What caused these things to happen?

This is a mutation, often genetic, but also could be caused by outside influences such as pathogens, injuries, or chemicals. Plant hormones may also play a role in this phenomenon. This mutation expresses itself as a malformation or cresting at the tip or growing point of the plant, also known as the meristem. We call this fasciation and it begins when the cells at a growing point of a plant start dividing in an uneven or asymmetrical fashion instead of the normal symmetrical pattern.

There are some plants we embrace for their fasciation. A common one is cockscomb celosia that is prized for its showy crested inflorescence. Cacti and succulents more commonly exhibit fasciation and we can see it in some of the crested cacti.
Take a close look at what is happening in your garden and landscape. Plant biology is fascinating!

Dog Days – A Good Time to Plan for Fall
Dog Star nights Astro Bob
The “Dog Days” are the hottest, muggiest days of summer. In the northern hemisphere, they usually fall between early July and early September. The actual dates vary greatly from region to region, depending on latitude and climate. Life is so uncertain right now. But, fall is coming.
In ancient times, when the night sky was not obscured by artificial lights, the Romans used the stars to keep track of the seasons. The brightest constellation, Canis Major (Large Dog), includes the “dog star”, Sirius. In the summer, Sirius used to rise and set with the sun, leading the ancient Romans to believe that it added heat to the sun. Although the period between July 3 and August 11 is typically the warmest period of the summer, the heat is not due to the added radiation from a far-away star, regardless of its brightness. The heat of summer is a direct result of the earth’s tilt.
Spending time outdoors this time of year is uncomfortable, potentially dangerous, due to the intense heat. However, the chinch bugs are very active in St. Augustine grass (for more information: http://edis.ifas.ufl.edu/lh036), and the summer flowers need water. So, take care of those tasks early in the day and then retreat to the air conditioning to plan your fall planting.
Plant tomato plants in August for fruit in October. Varieties such as Phoenix, Florida 91, Solar Set and Heat Wave II are good selections for setting fruit in high temperatures, should summer temperatures continue. Otherwise, try some of the newer UF/IFAS recommended varieties for fall planting in North Florida such as Bella Rosa, Tribute or Finishline. For more information on tomato selection refer to: http://edis.ifas.ufl.edu/in756. For information on other vegetables for fall gardening refer to the Florida Vegetable Gardening Guide: http://edis.ifas.ufl.edu/vh021.
Many bedding plants flower quickly and can add color to the fall landscape. These include pentas, African marigolds, torenia, zinnias, melampodium and scaevola. Other can be planted in October for blooms all

winter-long. Plan spaces and color themes for calendulas, pansies, snapdragons and violas. Add in ornamental cabbage or kale and some dusty miller to accent the garden. They too will perform through the cold. For more information on Annuals for the Florida Garden refer to: http://edis.ifas.ufl.edu/mg319.
Dependable fall blooming perennials include lion’s ear (Leonotis leonurus), pineapple sage (Salvia elegans), firebush (Hamelia patens), cigar plant (Cuphea micropetala), yellowbells (Tecoma stans) and firespike
(Odontonema strictum). Also, garden mums (Chrysanthemum sp.) and many different Irises will add color again in the spring. To gain information on perennials for Florida refer to: http://edis.ifas.ufl.edu/mg035.
Webster’s second definition of “dog days” is a period of stagnation or inactivity. But, even when the heat forces you to slow down on the labor-intensive work, there is plenty of gardening “activity” to do. Stay in the air conditioning and plan that spectacular fall and winter yard.
