Sandhill Milkweed – Attracting Butterflies in the Dunes

Sandhill Milkweed – Attracting Butterflies in the Dunes

Like finding buried treasure on a desert island, walking up on a mound of sandhill milkweed (Asclepias humistrata) may elicit cries of excitement from someone who understands what they’re seeing. And not unlike searching for pirate booty, there’s a bit of danger involved, too—milkweed is highly toxic.

Last month in the dunes of Perdido Key, our Master Naturalist class found robust clusters of eye-catching, pink-tinged leaves, blooms, and buds of sandhill milkweed. Also known as pinewoods milkweed, this variety thrives in dry, sandy soils. It is native to the southeast, found typically in the wilds of Alabama, Mississippi, Louisiana, Georgia, Florida, South Carolina, and North Carolina. Its genus name, “Asclepias” refers to the Greek god of healing—indigenous people have used the plant for medicinal purposes (dysentery treatment and wart removal, in particular) for centuries. The species name humistrata means “spreading,” which describes the growth habit of the plant. Milkweed is highly toxic, so we do not recommend trying any medicinal uses at home! The “milk” part of the common name refers to its sap, which is a thick, sticky, white substance containing that toxic chemical.

As the only food source for the monarch caterpillar, healthy milkweed plants are crucial for maintaining populations of the famous monarch butterfly.  The plant itself is rather complex and beautiful. Its five-petaled blooms grow in tight clusters, on stalks sticking several inches off the ground. The leaves are broad and a deep forest green, edged in the pale maroon/pink of the stems and flowers. The seedpods of milkweed are quite large (3-6” long), resembling pea pods and full of seeds. Each seed has a wispy white fiber attached, which helps it disperse in the wind like a dandelion. The fibers have been used for years as stuffing for pillows and mattresses, and were used for life jackets during World War 2.

The first cluster of milkweed we found was host to multiple monarch caterpillars, recognizable by their greenish-yellow, white, and black stripes. By the time you see caterpillars, the milkweed is already working its magic, transferring its toxins to the insects but causing them no harm. Monarchs have evolved the capability to digest and metabolize this poison, which would induce heart attacks in nearly any vertebrate animal.  Adult monarchs use several nectar sources, including milkweed flowers, and females lay their eggs on the plant so that their young can begin eating once hatched.

In the animal kingdom, red and orange are signs of danger.  The bright orange coloration of an adult monarch butterfly serves as a warning to would-be predators to exhibit caution, as the toxins from their food sources stay within the butterfly’s body. The copycat viceroy, soldier, queen, and Gulf fritillary butterflies benefit from this trait by using mimicry in their own orange coloration to ward off predators.

Pollinator Gardening – Tips for Apartment Living

Article written by Khadejah Scott, Horticulture/Agriculture/Natural Resources Agent – UF/IFAS Extension at Wakulla County.

Gardening for pollinators is not only beneficial for the environment, but it can also be a rewarding and fulfilling hobby. However, living in an apartment can pose a challenge for those who want to create a pollinator-friendly garden. But fear not! With a little bit of creativity and effort, you can still create a welcoming space for pollinators to thrive. Check out these tips to encourage pollinators at your apartment.

Choose Your Location

The balcony is the obvious first choice for your apartment pollinator garden. Alternatively, if your building has a roof, porch, terrace, or courtyard, check to see if you can use those spaces for a few plants.

Assess Your Size And Space

The majority of apartment dwellers value their available space strongly. Finding space for just you and your possessions, much less a garden can be difficult. But even the smallest areas have the potential to turn into green havens with a little imagination. Make sure your space gets adequate sunlight and is close to a source for watering.

Select Your Plant Types

One way to start your garden is by choosing the right plants. Diversity is the key to a good pollinator garden. Because each pollinator has its techniques for sourcing nectar and pollen, flowers should be as varied as the pollinators that visit them. Native plants such as Gaillardia (Gaillardia pulchella) are an excellent option as they provide food and shelter for local pollinators. Together with native plants, you may also grow annual ornamental flowers in smaller gardens that will thrive and provide an excellent source of nectar and pollen, like zinnias (Zinnia elegans),  or sunflowers (Helianthus annuus). Another best option is also to use culinary herbs. For instance, basil (Ocimum basilicum) and oregano (Origanum vulgareare) are fantastic nectar sources if you allow them to flower. One creative way to create a pollinator-friendly garden is by incorporating a variety of textures and colors. This can include adding different heights, shapes, and textures to your garden, as well as incorporating a variety of flower colors. You can also choose plants that bloom at different times of the year to ensure a consistent food source. This will attract a wide range of pollinators, including bees, butterflies, and hummingbirds.

Plant in Containers

Another important aspect to consider is the type of containers you will use for your plants. You can use anything from traditional pots to repurposed containers like old tires or wooden boxes. Just make sure that your containers have proper drainage and are large enough to accommodate your plants. Plants such as swamp milkweed (Asclepias incarnata), Blazing Star (Liatris spp.), and Black-Eyed Susan (Rudbeckia hirta) do well in containers.

Think Vertically

In a small area, vines can significantly expand the habitat that is available by climbing up a trellis or lattice against a wall or fence. Numerous native vines such as the Maypop (Passiflora incarnata) can go in large containers and are excellent sources of nectar and pollen for pollinators.

Include Bird Feeders And Bird Houses

An enjoyable way to observe birds up close and get in touch with nature is using bird feeders. Additionally, they enhance the natural food sources that birds can find near your garden. Bird houses also provide shelter to cavity-nesting species and increase the species of birds at your apartment.

Finally, make sure to supply a source of water for your pollinators. This can be as simple as a shallow dish or bowl filled with water or a small fountain. Just be sure to change the water regularly to prevent mosquito breeding.

Creating a pollinator-friendly garden in an apartment is not only possible but can be an enjoyable and rewarding experience. By following the tips above, you can create a welcoming environment for local pollinators to thrive.

To celebrate “No Mow March”, this month’s Gardening in the Panhandle LIVE was all about pollinators. “No Mow March” was inspired by “No Mow May” events that were originally organized in Great Britain then adapted by some of our more northern states. Lawns in the panhandle definitely need to be mowed in May, so we set our sights on March.

Most warm season turfgrass species don’t grow much (or at all) in March, but some people may feel the need to mow their lawns. If you feel the need to mow, we recommend you leave the borders of your lawn or a small area un-mowed. This will encourage flowering plants to bloom and bring more pollinators to your yard.

Butterflies are loved by many for their beauty, but they also pollinate a lot of our favorite plants. To encourage butterflies to visit your garden, try planting some things they like to eat. The publication “Butterfly Gardening in Florida” provides lots of information about bringing butterflies to your yard. Be sure to check out the tables in the article for information on seasons and life cycles. If butterflies aren’t your thing, then search for plants by pollinator species in this webpage on Nectar Plants. Some plants have Extrafoliar Nectaries to attract a diversity of insects.

If you’re interested in anything about any insect, then you’ll enjoy the Featured Creatures website. You can search by species name or by what they like to eat.

Not all bees live in hives. Some bees, like mason bees, prefer to live in above ground “houses” or “hotels”. You can build your own pollinator hotel if you follow the simple steps found in the article “Build Your Own Pollinator Hotel”. And here’s even more information on “gardening for bees”.

Not all pollinators are bees or butterflies or insects at all. Learn about all sorts of pollinators in the article “Pollinators: It’s Not All About the Bees”. Some of the best avian pollinators are hummingbirds.

Some of us live in the woods and need suggestions on shade loving plants. The article “Landscaping in the Shade” provides some good information on what plants can handle shady spots. A number of different ornamental gingers like the shade.

Turfgrass isn’t the only groundcover on the market. There are lots of alternatives like frogfruit and perennial peanut that attract pollinators.

What better way is there to attract native pollinators than to plant native plants?! Here’s a series of articles on native plants. If butterflies are what you’re after, then (native) milkweed is your plant of choice.

Some plants just like to be around each other. More information on companion planting can be found in the article “One Secret to “Organic” Gardening. Companion Planting”.

If you’re interested in being a part of “No Mow March”, the first step is to sign the pledge at go.ufl.edu/NoMowMarch. Also, be sure to record your “No Mow March” observations at iNaturalist.

Past episodes of Gardening in the Panhandle LIVE can be found on our YouTube playlist.

Pollinators…Under Your Feet?

Pollinators…Under Your Feet?

Every spring, a certain type of pollinator is busy in the yards and landscapes of our area. It may be alarming to see small piles of soil mounded up amidst carefully tended grass, but there is no need for concern. In fact, quite the opposite! The creatures making those mounds are bees, but they’re not the type that want to sting you. Instead, they’re harmless, solitary pollinators who just want a safe place to lay their eggs.

It’s easy to confuse a bee digging in the lawn or landscape for a yellowjacket and become alarmed. Yellowjackets are very different; they form hives underground consisting of hundreds or even thousands of individual hornets. Miner bees, on the other hand, each dig their own small burrow. Each miner bee is looking for the same sort of place to build a little hidey hole, so many individuals might be attracted to an area with prime real estate, so to speak. This can lead to large numbers of mounds in close proximity to one another, but again, there is no reason to be alarmed.

Each female bee will dig a vertical tunnel up to a foot and a half deep, then make side chambers lined with waterproof material. She stocks each chamber with pollen and nectar, then lays her eggs. Larvae remain in the ground until the following spring. When they emerge as adults, they start the whole process over again.

It is important to understand and protect pollinators such as the miner bee, because they all provide a valuable service to the environment. Pollinators ensure that all the plants around us can reproduce, by carrying genetic material from one flower to another. You can help these little messengers in their task by learning about their habits and making a little room for them in your landscape. When you see these small mounds of soil in your yard, don’t worry! The bees will do their job and the next rain will likely wash away the soil.

Consider attracting other pollinators as well! Plant flowers that attract native pollinators, or leave an area of your landscape “wild”. Let dead plant stalks remain over the winter as nesting sites for pollinators, or try letting a patch of native wildflowers escape mowing for some time in the spring.

Importance and Types of Pollinators – Did You Know?

Importance and Types of Pollinators – Did You Know?

Do you enjoy a tasty bowl of fruit in the morning? Or maybe a hot steaming cup of coffee? If the answer is yes, then raise (or tip) your hat to our pollinators. About 75% of food crops depend on pollination to some extent, but pollinators provide the bulk of the pollination for over 80% of the world’s flowering plants. A pollinator can be birds, bats, or even small mammals but, insects such as ants, bees, beetles, wasps, butterflies, and moths do the bulk of the pollination that affects our daily lives.

Plants normally benefits from attracting a particular type of pollinator to their flowers, ensuring transfer and hopefully resulting in reproduction. The pollinator benefits from its adaptation of a particular flower with different traits to access nectar and pollen. These floral traits include odor, color, size, flower shape, reward type, amount, nectar composition, and timing of flowering. This plant pollinator interaction is known as pollination syndrome.

Did you know ­–

  • That tubular red flowers with a lot of nectar often attract birds.
  • Also, foul smelling flowers attract carrion flies or beetles.
  • Butterflies and moths can help spread pollen; however, they don’t have any specialized structures for collecting pollen.
  • Beetles pollinate more than 80% of all flowers – clusters of flowers are ideal because beetles are clumsy fliers.
  • While bees are drawn to plants on the blue, white, purple, and yellow color spectrum. Bees possessing hairs and other specialized anatomical structures that can readily collect and transfer pollen, making them an important plant pollinator. However, the honey bee, (Apis spp.) is the world’s top pollinator and is responsible for one-third of what we eat, yet they are just a small representative of all the bee species.

Did you Know-

Everyone can contribute to pollinators by creating a home garden. Pollinators will make use of food and habitat anywhere it is found – roadsides, open fields, pastures, backyard flower gardens etc. One can be pollinator friendly by doing any of the activities below:

  • Plant an assortment of plants – varying in color, size and type to support a greater number and diversity of pollinators. 
  • Plant native plants – as they are considered the best choice due to their abundance of nectar and pollen, among other benefits.
  • Use little or no pesticides – instead maintain a sustainable garden with the suitable plant species that will support natural beneficial insects—reducing the need for pest control.
  • Educate others about the importance of pollinators.
  • Seasonal planting – Choose pollinator plants that bloom in spring, summer, and fall. Timing is crucial – plant flowers in clumps that bloom in early spring (emerging winter hibernation) and late summer (preparing for hibernation) so bees have adequate food supply.
  • Provide habitat or install bat boxes. Bats play a vital role in pollinating flowers and dispersing seeds.
