Butterflies are not only beautiful to look at in your landscape; they serve as important pollinators and indicators of the health of our environment. Attracting them to your garden and incorporating some features to get them to stay and make it their home involves a little planning ahead of time for optimum results.

Choose a location that provides some protection from wind. Trees and shrubs that provide wind protection also serve as a safe harbor from rain and predators. The garden should be mostly sunny with some part sun areas. Ensure that any new plantings have access to a convenient irrigation source so they can be successfully established and maintained in good health.
Now you’ll need to choose the plants. Adults feed on the nectar of many flowering trees, shrubs, perennials, and annuals and, fortunately, there are usually many choices that will meet your site requirements and your taste preferences. In order to keep the butterflies in your garden, certain plants need to be available to serve as host plants for their young. Determine which species of butterfly is common in your area and that you want to attract. Most species have very few plants on which the caterpillars can feed so those host plants need to be chosen wisely. Determine whether any of the plants you already have are host plants and they can be integrated into your butterfly garden. For example, cassia is a host plant for the Cloudless Sulphur and citrus is a host plant for the Giant Swallowtail.
In choosing your nectar plants, select those that are native or Florida-Friendly as they are lower maintenance, giving you less trouble in the long run. Choose plants that have flowers in a variety of color, size, and shape. Different butterflies like to feed at different elevations, so choose trees, shrubs, perennials, and annuals of varying heights. In order to have nectar available throughout the time when the butterflies occur, include plants that bloom at different times of the year. And include some plants that bloom from spring to late fall, like pentas or moss verbena.
Larger plants should be placed in the background with smaller plants layered in the foreground. When you plant smaller annuals and perennials, place them in masses to better attract the butterflies. Consider placing host plants in an area that is in close proximity to the nectar plants, but in an area of your garden that is not a focal point. Host plants can get quite ragged looking from hungry caterpillars!
Good maintenance practices will enhance the health of your garden. Regular fertilization and irrigation if needed will help keep your plants in bloom and healthy; healthy plants are less susceptible to disease and pests. Avoid pesticides as they may harm the very creatures you are trying to attract. Never use Bt or systemic pesticide. If you must, target a pest with lower risk oils or soaps and then only treat the affected plants. Lastly, be aware of beneficial insects that will help you achieve satisfactory control of a pest.
Now that your plants are placed there are several things to do to make your butterfly garden complete. Add a spot where water can puddle on the ground for the adult butterflies to drink. They require minerals from the soil that get dissolved in the water. Also add a rock or log in a sunny spot where butterflies can rest and sun themselves. And consider placing a comfortable place for you to sit and enjoy the beauty of your garden and its inhabitants!

Butterfly Gardening in Florida

Everyone with a landscape can make a difference for pollinators. Simply Having Areas Reserved for the Environment enables homeowners, land managers, farmers, individuals, corporations, schools, roadside managers, and golf courses to increase the number of pollinators in the area by making conscious choices to include plants that provide essential habitat for bees, bats, birds, butterflies, moths, beetles, and hummingbirds. What better time than during National Pollinator Week, June 15-21, 2015.
Initiated and managed by the North American Pollinator Protection Campaign, National Pollinator Week was unanimously approved and designated by the U.S. Senate in 2007. Each year since, the U.S. Secretary of Agriculture has signed the proclamation in an effort to address the urgent issue of declining pollinator populations.
Worldwide there is evidence that pollinating animals have suffered from loss of habitat, pesticide misuse, competition from invasive species, disease, and parasites. Many pollinators are federally “listed species”, meaning that there is documented information confirming the disappearance and/or significant population reduction in natural areas. The United States has lost over 50% of its managed honeybee colonies over the past ten years. The European Union has been so concerned that they invested over $20 million investigating the status of pollinators in Europe.
Pollinator health affects everyone. Worldwide, roughly 1,000 plants grown for food, beverages, fibers, spices, and medicines need to be pollinated by animals in order to produce the goods on which we depend. Food and beverages produced with the help of pollinators include: apples, blueberries, chocolate, coffee, melons, peaches, potatoes, pumpkins, vanilla, almonds, and tequila. In the U.S., pollination by honey bees, native bees, and other insects produces $40 billion worth of products annually.
The native plants that can be identified and preserved or introduced include trees, shrubs, vines and perennials. Some of them include: Eastern Redbud (Cercis canadensis), Highbush Blueberry (Vaccinium spp.), Passionflower (Passiflora spp.), Coreopsis (Coreopsis spp.), Goldenrod (Solidago spp.), Black-eyed Susan (Rudbeckia hirta), and Butterfly Milkweed (Asclepias tuberosa). Simply identifying and avoiding damaging many of the existing native plants will allow anyone to provide important homes and food for many different pollinating animals. During National Pollinator Week S.H.A.R.E. your space.

Gardening for Pollinators
Minimizing Honey Bee Exposure to Pesticides

Bees have been disappearing at an alarming rate and continue to vanish without a trace. Why should anyone care? Well, they matter a lot more than most people think. Bees are the overwhelmingly dominant pollinator for most food crops. Native bees in the United States are responsible for pollinating over $15 billion worth of agricultural commodities annually. However, native bee populations are in decline due to habitat loss. At the same time, managed colonies of European honey bees have suffered a 50% decline over the past few decades. Numerous other pollinating insects are facing the same fate.

As the spring planting season is upon us, it’s exciting to think about all the wonderful produce we will have this summer. But, without pollinators many of these crops would not be available. The majority of fruit and vegetable food sources we eat are dependent on insect pollinators. One of every three bites of food Americans consume comes from a plant visited by bees or other pollinators.
As declining numbers of farmers work to meets the need of increasing populations, they are forced to make choices on alternative to chemicals for pest control. “Good bug blends” of flowers can help attract pollinators as well as beneficial insects that suppress harmful pests. Establishment of these meadows can be done on a small or large scale and in any habitat. One approach to “bring back the pollinators” is to intercrop with blooming plants that attract insects. Selecting a diversity of plants with different flower sizes, shapes and colors, as well as various plant heights and growth habits, will encourage the greatest numbers of pollinators. It is important to provide a continuous source of pollen and nectar throughout the growing season. At minimum, strive for three species to be blooming at any one time; the greater the diversity the better.
To enhance the garden, choose flowering plants that also provide shelter for beneficial insects. Many companion plants are suitable habitat for predators and parasitoids. Research in Florida has demonstrated that predatory minute pirate bugs can build to high numbers in sunflowers. The favorite food of minute pirate bugs is Western flower thrips. So, planting sunflowers on the perimeter of vegetable crops, such as peppers, can greatly reduce the damage caused by the thrips. Similar results were found with the planting of sorghum to attract beneficial mites and intercropping with buckwheat to house syrphid flies and parasitoid wasps. The garden vegetables experienced fewer spider mite, whitefly and aphid problems. Crimson clover, Hairy vetch and cosmos are other annual seed crops that can aid in attracting pollinators and harboring beneficial insects.

Insectary meadows can be created in the landscape and along roadways, not just in the garden. For more permanently planted areas, native wildflowers, grasses and woody plants serve as larval host plants for butterflies, and also provide nesting and overwintering sites for bumble bees, predacious beetles and other beneficial insects. Native perennial wildflowers such as blanketflower, tickseed, black-eyed Susan, partridge pea, narrowleaf sunflower, milkweed, beebalm, goldenrod and silkgrass can be installed in the spring as potted plants or seeded in the fall. Seeds require exposure to cold temperatures and damp conditions before germination can occur. In Florida, the best time is November to February.
Though grasses do not offer nectar or high-quality pollen, it is often useful to include at least one native bunch grass or sedge. Short, clump-forming grasses are preferable to large, spreading grasses. Hedgerow planting of woody species is a way to provide winter-blooming plants vital for supporting pollinators. Woody plants and grasses provide more than forage for pollinators, as many native bee species nest in the stems of plants or in the undisturbed ground underneath plantings. Suitable grasses include: beaked panicgrass, purple lovegrass, Muhly grass, broomsedge,little bluestem, wiregrass and toothache grass. Favored woody species that make good “beetle banks” include: fetterbush, American beautyberry, saw palmetto, Chickasaw plum, red maple, sparkleberry, Dahoon holly, redbud, blackgum, magnolia, buttonwood and sourwood.
Regardless of whether the objective is to establish herbaceous or woody vegetation, the time and effort spent on eradicating undesirable plants prior to planting will result in higher success rates in establishing the targeted plant community. Choose level, open sites that receive full sunlight and have limited weed populations. If perennial weeds are a problem, the use of herbicides that have no soil residual (e.g. glyphosate) may be necessary.

Rain gardens are an easy way to return water to our aquifer, reduce erosion, and help prevent stormwater runoff.
Running down the driveway or patio, rainwater can pick up lawn chemicals and pesticides. A rain garden is basically a low section of the landscape planted with native plants that like to get their “feet” wet. The garden collects rainwater, giving it a chance to “strain” out impurities before draining into the aquifer.

They work best when they’re placed at the bottom of downspouts or naturally low spots in the landscape, usually where water tends to puddle. They’re especially useful for collecting runoff from paved surfaces. Rain gardens can be any size or shape and can attract thirsty wildlife.
When selecting plants, you’ll need to consider how much sun your site gets and how much space is available. Make sure you select plants that are not just water-tolerant, but also drought-tolerant for the times between rains.
Rain gardens rely on plants that will survive dry spells but then soak up excess stormwater during Florida’s rainy months, preventing the water from running across your landscape.

Include different types of plants in your rain garden to create a complete and cohesive look that will provide year-round interest. The following is a short list of flowers, shrubs, and grasses that would perform well in a rain garden.
Flowers:
- Blue flag iris
- Goldenrod
- Swamp sunflower
- Spider lily
- Milkweed
Grasses:
- Florida gamma grass
- Muhly grass
- Wiregrass
Shrubs:
- Virginia willow
- Buttonbush
- Wax myrtle
Here is a list of native plants that will do well in your North Florida rain garden. As always consult your local Extension Office for more information. All of the information in this article was provided by UF/IFAS Extension.

When you look out at your landscape nobody has to tell you that winter temperatures in Northwest Florida Afterwards, the temperatures warm up and you feel compelled to do something about it. You just need to “turn your back and slam the door”. “Conceal, don’t feel; don’t let them know”. Cold injury can affect the entire plant or just certain plant or parts such as fruits, flowers, buds, leaves, trunks, stems, or roots. Many plant parts can adapt to tolerate cold. Root systems in the landscape are seldom ‘frozen’ in Florida. “The cold never bothered” them “anyway”. While dead, unsightly leaves may be removed as soon as they turn brown after a freeze, the remaining dry looking stems serve as food storage and should be allowed to remain. If they are removed before the weather is warm enough for the plant to resume growth, the root system may not be enough to support the plant and it will die. So, “let it go, let it go, let it go”. “The perfect” landscape “is gone”. “The past is in the past”. “It’s funny how some distance makes everything seem so small”.Tropical plants and summer annuals do not adapt or harden to withstand temperatures below freezing, and many suffer injury at temperatures below 50°F (10°C). Subtropical plants can harden or acclimate (become accustomed to a new climate) to withstand freezing temperatures, and properly conditioned temperate plants can withstand temperatures substantially below freezing.
Recently planted, unestablished plants may be more susceptible to cold injury. One type of winter injury is plant desiccation or drying out. This is characterized by marginal or leaf tip burn in mild cases and totally brown leaves in severe cases. Desiccation occurs when dry winds and solar radiation result in the loss of more water from the leaves than can be absorbed and/or transported by a cold root system. Plant water needs should be checked after a freeze. Plants may have lost substantial moisture during a windy freeze. Plants will transpire (lose water vapor) on a sunny day after a freeze. Cold injured wood can be identified by lightly scraping the bark with your fingernail and examining the color of the cambium layer (food conducting tissue) just underneath. Green tissue indicates the plant is still alive at that point; black or brown coloration indicates dead or injured tissue. 
After a particularly harsh cold event, some plants may be very slow to recover, so some patience is required. “It will rise” with “the break of spring”. Branch tips may be damaged while older wood is free of injury. Delay pruning until new growth appears next spring to ensure that live wood is not removed. In the meantime, take Elsa’s advice and “let it go, let it go, let it go”. You may be “too relieved to grieve”. I hope I haven’t infringed on any copyrights by letting you know “It’s okay to put off the yard work in the name of plant physiology”.
Enjoy the holiday season!

Here’s a beautiful native perennial wildflower that is easy to grow and generally available in the independent nursery trade. In the wild, you can encounter them at the edges of woodlands and ponds as they prefer moist areas. Blue mistflower, Conoclinium coelestinum, performs well as a perennial in the home landscape but does spread easily by seed and will spread in the garden. It also spreads through underground rhizomes which allow it to form large clumps. This is an advantage for the informal garden, however, the gardener who prefers a more formal look will have a bit more maintenance in controlling that spread.
The abundant flowers look like bluish-purple puffballs on the top of the stems. The color is unusual and adds a striking touch in the garden. The bloom season is mid-summer to mid-fall. Butterflies are frequent visitors, making this an excellent addition to your butterfly garden.
Blue mistflower has a full rounded form and will grow to 3 feet under optimum conditions. Leaves are opposite and have a triangular shape. Growth and blooming is best in full sun to part sun conditions.
Give it a try!
