Bold Colors for Your Fall Landscape

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

Florida Wildflowers: Narrowleaf Sunflower

Florida Wildflowers: Narrowleaf Sunflower

In the midst of your September strolls through natural Florida, you may come across this native beauty, the narrowleaf sunflower, Helianthus angustifolius. Another common name is swamp sunflower. I found this gorgeous patch in the photo close to the shore of Apalachicola Bay. It occurs throughout Florida and north throughout much of the eastern United States. Florida is fortunate to be home to over 20 native species of sunflower.

This perennial starts blooming in late summer and dazzles admirers throughout autumn. The 2 to 3 inch flowers with bright yellow petals and brown centers are attractive to butterflies and other pollinators. What a great addition to your butterfly garden!

Plants generally grow to about 2 foot tall but they can grow a bit leggy to 6 foot. If desired, keep them more compact through pruning in late spring. Clumps can be divided every few years to spread them out or to share with friends and neighbors.

Like all sunflowers, it loves full sun but can tolerate some light shade. Narrowleaf sunflower is salt and flood tolerant and will do well in most soil types, however it does best in consistently moist conditions.

Narrowleaf sunflower plants may be difficult to find in the nursery trade but they can be readily started from seed.

Now that summer is in full swing, many of us are spending more time on our gorgeous Gulf beaches. Sea turtles are nesting and everyone gets excited at sightings of dolphins, sharks, and the Blue Angels. However, we have another recent visitor to our beaches, and this one isn’t spending money and renting condos. It has moved in from out-of-state and plans to stay, potentially wreaking havoc to our fragile beach dune ecosystems.

Florida is no stranger to invasive species. Reports and stories of pythons, popcorn trees, feral pigs, and others can be found everywhere. As a matter of fact, Florida and Hawaii have more problems with exotic plants and animals than any of the other states.

Beach Vitex (Vitex rotundifolia) is originally from the coastal areas of the western Pacific. It was brought to the United States by North Carolina State University in the 1980’s to restore dunes along coastal Carolina after severe storms. The plant is very salt and drought tolerant and performs well in direct sun and sandy soils; perfect for our coastal beaches. It grows about 3 feet tall and produces branches that extend along the surface of the sand over 60 feet from the tap-root. The flowers are lavender and found in the spring. By midsummer the flowers have dropped and pea-size dark fruit is produced. The fruit is also salt tolerant and can be carried by ocean currents as well as birds. The plant seemed a perfect choice for restoration projects.

And then…

And then it began to overgrow the primary dune system, choking the majority of the native plants including sea oats. The shrub size of the plant and the presence of vertical tap roots in lieu of fibrous ones did not suit it well as a dune forming plant; some studies found that it actually increased the erosion of some dune fields. Beach vitex releases allelopathic compounds, reducing the water content of the soil which stresses native plants thus reducing competition for space. And then there are the sea turtles. Evidence indicates that the growth of this plant over the primary dunes has made it difficult for female turtles to find nesting areas, while fast growing branches grow over incubating nests and make it difficult, if not impossible, for the hatchlings to emerge. The plant has become such a problem that it has been dubbed “Beach Kudzu” and there is a two-state task force to remove it.

Beach vitex has dispersed north to Virginia and south into Georgia. Currently it has been reported in only three Florida counties; Duval, Santa Rosa, and Escambia. Because of the few records in our state it is not currently listed as an invasive plant in Florida. The problem is, most biologists will tell you that the best way to eradicate an invasive species is to get it early. However most do not see the introduction of a new plant or animal as invasive until it becomes established and difficult to remove.

Natural Resource Agents with UF IFAS Extension are tracking the locations along the coast of the panhandle where this plant may exist. If you believe you may have it please let us know so that the location can be recorded. If you are interested in removing the plant we recommend cutting back to the tap-root. Dab the remaining tap-root with Round-Up. It is best if the remaining parts of the plant do not leave the property; if legal it is ok to burn. If you must transport it off the property we recommend it be dried on concrete and then double bagged before removing to the landfill. In many cases it may take several years to completely remove this plant. If you have any questions about this plant please call your local county Extension Office.

Florida Betony: Both Edible Native and Weed

Florida Betony (Stachys floridana), commonly called rattlesnake weed, is a Florida native plant. It’s thought to have been confined to Florida until it was moved to other Southeastern states during the 1940s or 1950s in nursery containers. It is now found from Texas to North Carolina. Its square stems are characteristic of the mint family of which it is a member.

Underground white, fleshy tubers, which resemble a rattlesnake’s rattle in shape, provide the main means of reproduction. Pinkish-purple flowers are followed by a dried fruit that splits open releasing tiny seeds, which are a lesser means of reproduction. The white tubers have been used for hundreds of years as a starchy vegetable and are sometimes boiled like peanuts.

The tubers make Florida Betony tough to control. Even when above ground foliage and stems are killed due to herbicide use, the tubers allow the regeneration of the plant repeatedly. When attempting to control this weed, it helps to be more persistent than the plant. Many people give up.

Even though it is a perennial, the above-ground portion of the plant grows during fall and spring and becomes dormant during hotter weather.

You can remove the weed by digging, making sure to remove the entire root system (including the tubers). But persistence and patience is required. Herbicide control usually involves repeat applications approved products  in lawns. Glyphosate herbicides such as Roundup can be used to control Florida Betony in plant beds. But do not get the herbicide on any green portion of desirable ornamentals.

Always refer to the product’s label for specific uses, application rates and turfgrass tolerance when using any herbicide.

So, why not just dig up the Florida Betony in your lawn and have a native plant feast?

How Do I Find Plants to Suit My Landscape?

How Do I Find Plants to Suit My Landscape?

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.

FFL AppUF 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! FFL Guide to Landscape Design and Plant Selection

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!

 

Florida Wildflowers – Historically Resilient

The summertime often reminds us of our uninhibited spirit. With Independence Day not far off, Floridians will be celebrating the freedom of our nation while battling the oppressive climate you can’t seem to escape this time of year. As we approach the apex of heat and humidity here in Florida, we would do well to remember the tenacity of our native wildflowers and their “spirited” survival of Florida’s extreme conditions.

Historically, Florida’s landscape was alive with color throughout the seasons. Through urbanization and cultivation we’ve lost a large part of that legacy; however, we can reestablish some of Florida’s colorful past in our own yards and neighborhoods.

In order to ensure successful planting of wildflowers it is important to properly select and prepare your site. You will want to choose a sunny-well drained area and cut any existing vegetation to the ground. It may be beneficial to put down sheets of cardboard to smother what’s left of the vegetation. This is best done in the summer in advance of fall planting.

Planting is best done late August to early September in North Florida. Soil-to-seed contact is critical so 1 day before seeding, or just prior to seeding, firmer soils need to be lightly scratched with a rake. Sandy soils might have to be made more firm to ensure that seed do not sink too deep. Broadcast the wildflower seeds at the recommended rate then press them into the soil by walking around on the planting site.

Wildflower seeds require adequate moisture during germination. After planting irrigate the site with about 1/4 to 1/2 inch of water daily for the first few weeks. After that, irrigate with about 1/2 inch water only if the wildflowers show signs of drought stress. Once established though, the meadow needs very little, if any, irrigation. Fertilizers should be avoided altogether as they promote the growth of aggressive weeds. Many of Florida’s native wildflower species are adapted to and perform well in soils with low fertility. Your wildflowers will re-send themselves if given the opportunity so wait until seed have matured before deadheading or mowing. Cut no lower than six to eight inches to avoid damaging the crowns of grasses and wildflowers.

To successfully cultivate a wildflower meadow in your home landscape, it’s helpful to select plants with the qualities to fit the conditions at your site. Also, consider blooming dates of flowers in order to provide color and interest for your landscape spring through fall. While not always possible, it’s best to purchase seeds and plants known to be Florida ecotypes. Consult with local nurseries and garden centers for more information on plant and seed availability and seeding rates. You can always contact your local Extension Office for more information. Other good sources of information are the Wildflower Seed And Plant Growers Association, Inc. (www.floridawildflowers.com); Association of Florida Native Nurseries (www.afnn.org); and the Florida Wildflower Foundation (www.floridawildflowerfoundation.org).

Growing wildflowers can restore a special sense of natural history close to home. So if you are looking for an “explosion” of color that will stand the test of time, Florida’s native wildflowers will not disappoint.
