I think it’s safe to say fall is officially here. Shouts can be heard from local football stadiums, occasionally a crisp fall breeze will send us looking for a light jacket, and coffee shops are pushing all things pumpkin. Now that we can officially appreciate the cooler fall weather, it may be time to stretch our legs and marvel at the spectacular show of color our landscapes are putting on. Here are a few plants that are showing off this time of year.
Firebush (Hamelia patens) – This charming Florida native will delight everyone with beautiful orange-red flowers throughout most of the year. Hummingbirds and butterflies enjoy the nectar in the flowers. Firebush can reach a height and width of 8 to 12 feet. It is a fast growing plant that will grow well in part to full sun environments.

Salvia (Salvia spp.) – Salvias are great plants for bringing butterflies and hummingbirds to your garden and as a bonus, they have no serious pests. With hundreds of annual and perennial species coming in an array of colors and sizes, you can easily find one or more to complement your landscape. Salvias perform best in full sun environments and are considered drought tolerant.

Turk’s Cap (Malvaviscus arboreus) – Turk’s cap can add a cheerful pop of color at a time when little else is blooming. This old-fashioned Florida-Friendly shrub like perennial is related to the hibiscus. It’s known for its bright red flowers that always seem ready to open, but never do. Turk’s cap starts blooming in summer and keeps going until through winter, unless hit by a hard frost. It can grow in full sun and reach up to ten feet tall and ten feet wide, so give it room to grow. This easy-care native perennial requires little maintenance once it’s established.

Coleus (Solenostemon scutellarioides) – When imagining fall color we often don’t consider coleus. However, the vibrant foliage can add interest to any landscape throughout the fall. Coleus is prized for its colorful foliage, which comes in shades of green, yellow, pink, red, and maroon. Coleus varieties can range from one to several feet in height. They can be used in hanging baskets, containers on patios, or in landscape beds. Coleus prefers partial shade and you can pinch the growing stems of young plants frequently to encourage dense foliage. Keep an eye out for mealybugs on coleus and use insecticidal soap if problems develop

Many species of butterflies are flitting through summer gardens but a special butterfly has recently made its appearance in perennial gardens. The Blue butterfly bush, Clerodendrum ugandense is a mid to late summer blooming plant that has unique flowers resembling butterflies.

During our hottest days, light blue flowers appear above attractive green foliage. Plants may grow between 6 and 10 feet in height when provided with partial shade and moisture during the warm season. Although butterfly bush is a frost sensitive plant, it will likely return from the roots in hardiness zones 8 and 9. Even when replanted in the spring, it grows well enough that you will enjoy a flowering display by summer’s end. Plant your butterfly bush to accommodate a spreading growth habit and where garden visitors can get a close view of the interesting flowers.

Attracting Butterflies into Your Landscape
Have you been itching to add some life and color into your landscape? Why not plant a butterfly garden?! Butterfly gardens are a great way to add movement and life to an otherwise stagnant landscape. Most butterfly gardens are not only an attractant for our Florida butterflies, but are also a magnet for hummingbirds and beneficial insects. To start your garden all you need are a few key plants.

Incorporate at least one host plant and one nectar plant into your garden. The host plant provides a suitable habitat for the female butterfly to lay her eggs. These eggs will hatch and the baby caterpillars will eat the leaves of the host plant. Host plants are often not as showy as nectar plants, nor are they even necessary to attract adult butterflies. However, while nectar plants invite butterflies into your garden to feed, host plants offer them a reason to stay and reproduce. And you can watch this entire cycle unfold in your own garden!
Most of your butterfly attractant plants will do best in full sun to partial shade. Try not to apply pesticides in areas where you want to maintain healthy caterpillar/butterfly populations. Providing water for butterflies is very important and easily done. One option is to fill a clay tray with sand and then place a rock in the center, where the butterfly can perch. Keep the sand wet, but avoid standing water. Feel free to contact your local extension office for more information on our winged friends!

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.
In ancient times, when the night sky was un-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, 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 tomatoes 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 Tomato Cultivars for Production in Florida. For information on other vegetables for fall gardening refer to the Florida Vegetable Gardening Guide. Plan to attend the Fall Gardening program at the Extension office this September.
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 Gardening with Annuals in Florida.
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 Gardening with Perennials in Florida.
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.

Burgundy-leaved crapemyrtle is one of the most exciting breeding accomplishments in years. Unlike previous selections, many new crapemyrtle cultivars have leaves that retain dark burgundy coloration from spring budbreak through fall leaf drop. These plants add bold leaf color to a plant already known for its flower power.

As is typical of many new plant introductions, the new crapemyrtles are grouped and sold in series, most of which are patented and/or trademarked. Delta Jazz™ was the first crapemyrtle with burgundy-bronze leaves all summer long. This year Delta Jazz™, with pink flowers, is being joined by Delta Eclipse™ (purple flowers). Future years will see Delta Breeze™ (lavender flowers) and Delta Flame™ (red). All have burgundy to bronze leaves from spring through fall and are expected to be mid-size, maturing at heights of 8 to 12 feet.
Another new series with burgundy leaves confusingly is being sold under two names: the Ebony series and the Black Diamond™ series. ‘Ebony & Ivory’ features white flowers that contrast nicely with dark burgundy leaves on red stems. ‘Ebony Embers’ has red flowers on plants with dark burgundy leaves on purple stems. ‘Ebony Fire’ has flowers that are bright red and its leaves are medium burgundy. ‘Ebony Flame’ has dark red flowers and dark burgundy leaves. Finally, ‘Ebony Glow’ is named for its blush white flowers on dark red stems with dark burgundy leaves. These selections are also sold as Black Diamond™ Pure White, Black Diamond™ Red Hot, Black Diamond™ Crimson Red, Black Diamond™ Best Red and Black Diamond™ Blush, respectively. All are expected to grow 8 feet or more in height (regardless of the name!).

The First Editions® Magic™ series of crapemyrtles includes two new selections with burgundy leaves. Moonlight Magic™ has the darkest burgundy leaves I’ve seen so far. Flowers are white and the burgundy leaves are glossy and narrow on a plant expected to grow to a height of 8 to 10 feet. Maturing at 4 to 6 feet, Midnight Magic™ has leaves that are a dull burgundy while flowers are dark pink. Note that other cultivars in the First Editions® Magic™ series (‘Coral Magic’, ‘Plum Magic’, and ‘Purple Magic’) have green leaves.
These cultivars are too new to know how well they will perform in north Florida and the Gulf Coast. The best place to view these cultivars side by side is at the LSU AgCenter, Hammond Research Station, in Hammond, LA. There, Dr. Allen Owings has developed a beautiful garden where he is evaluating crapemyrtles and many other plants. For more information and to read Dr. Owing’s comments on new crapemyrtles, visit http://www.lsuagcenter.com/en/our_offices/research_stations/Hammond/.
All these new cultivars will have the brightest burgundy leaf color when plants are grown in full sun (at least 6 hours of direct sun each day). Any amount of shade will likely result in pale burgundy or burgundy-green leaves, as well as reduced flowering and growth. As with other crapemyrtles, these new cultivars are tolerant of drought, heat, rain, humidity and all but wet soils. When buying crapemyrtle, place the plant in a location where it can grow to its full height without the need to prune it regularly. After planting, sit back and enjoy these crapemyrtles’ bold burgundy foliage as well as the abundance of colorful flowers!

We all seem to have this dilemma: A desire to re-landscape or just add a few plants to an area, but not knowing what would be the best choice. Plants need to be compatible with their location. The right plant should be chosen for the right place. Many have particular light, moisture and zone requirements in order to do their best. The ultimate size of the plant is also an important consideration; if you want to avoid constant pruning, choose plants that only grow to size you would like to ultimately have. Some great resources are provided below to get you the information you need.
UF IFAS Extension has a brand new app for your mobile device or web! The app contains a database of over 400 Florida-friendly plants is searchable by plant name, type, shape, native status, light requirements and more. The yearly subscription is only $1.99 to have great info on the go.
The downloadable 104-page Florida-friendly Landscaping Guide to Landscape Design and Plant Selection not only has photos and detailed information about plants by category, it also has great ideas on how to improve your landscape design! 
UF’s Florida Yards & Neighborhoods maintains a searchable Florida-friendly Plant Database. Make choices based on region, plant type, light and moisture quantity, soil texture salt tolerance.
For native plants, the Florida Association of Native Nurseries has two websites where you can find plants for your particular zone, plant community (like at the beach or in pine flatwoods), plant type and by wildlife usage. There is a site designed for nursery professionals that lets you find local wholesale growers and also a similar site for homeowners that has resources on where to find desired plants at local nurseries.
Speaking of native plants, the Florida Native Plant Society also has a searchable list of plants appropriate for your particular needs.
Gardening Solutions has lots of great information for lawn, landscape and garden by category, and it is easily accessed.
Happy Gardening!
