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

There are areas in most landscapes where it just is not practical or possible to bring in the tiller and create a flowerbed. A little imagination, a decorative container and appropriate plants can turn a bare spot into a splash of color.
Colorful containers bring life to your small spaces.
Consider using a container of annuals to add color to a backyard deck or a paved entrance way. Or what about that area under the tree where grass doesn’t want to grow and where it would be difficult to till without damaging the tree’s roots and the tiller? How about the dry spot where there is no irrigation but where it would be more practical to occasionally hand water a well-placed container of colorful caladiums?
A wide variety of flowering annuals work well in containers. But be sure to select plants based on the exposure. Some annuals will quickly bake from full sun exposure and others will become leggy and bloom poorly in a shady location.
Impatiens and begonias do well in shaded places and remain in flower almost continuously. Caladiums with their colorful leaves also do well in containers in shady areas.
It’s more difficult to grow container plants in full sun but there are some annuals to consider for sunny spots. A few to consider include blanket flower (Gaillardia), portulaca and salvia.
There are many other annuals that can be successfully grown in containers. There are even sun-tolerant begonia and sun coleus varieties for full-sun places.
Don’t be afraid to try something different. To learn more about this topic, please see:

If you are looking for flower colors to match the heat of June, Red hot poker, Kniphophia uvaria has the blooms that match the season. Also known as the torch lily, this perennial performs well in full sun areas with well-drained soil. Leaves about 3 feet long and 1 inch wide form a clumping plant over the years to about 3 feet in height and 2 feet in spread.
The highlight of the plant are the flowers that form in May and June. Stalks grow above the foliage holding clusters of tubular flowers that emerge red/orange and mature to yellow. Flowers are often in transition between the two colors. Remove flowers after they fade.
Red hot poker is a low maintenance plant along the Gulf Coast. Extreme cold may set plants back a little but clumps grow well during winters with average cold temperatures. Plants can be divided after several years but the bloom cycle may be delayed following this practice.

An easy to care for perennial to add to your flower garden is the coneflower, Echinacea purpurea. The daisy-like flowers stand tall above the foliage on sturdy 2 to 4 foot stems. Blooms appear about the last part of April or the first of May in the Florida panhandle and last throughout the warm season until late fall. This Florida native reliably comes back year after year. Plant coneflower in part to full sun in rich but well-drained soil for best results.

Coneflowers are traditionally purple but many new colors and variations of their form have become available from the horticultural industry. You can find them in white, yellows, pinks, oranges, and greens as well as all shades of lavender and purple. No matter what color you choose, the blooms will attract a host of butterflies and other pollinating insects. In order to protect these delicate creatures, avoid the use of pesticides when they are present.
Once you have a few coneflowers, you will notice that the clumps will grow in time and new plants will sprout from seeds left behind by the spent blooms. In our demonstration garden, this has created a stunning display that has been allowed to take over one of the garden beds. When any one clump gets too big, the number of blooms can decrease and it may be time to dig up the clump and divide it. This is a great opportunity to expand your coneflower bed or share them with some friends or neighbors!

Butterfly Gardening

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.
