In Bloom

We've finally replanted the butterfly garden, and although it still really needs a new layer of mulch, at least the plants are in and doing well.


The key to a good butterfly garden is including both host plants and nectar plants. For the nectar plants, using different colors and heights is also effective, and grouping plants together in clusters of colors gives a nice aesthetic and the bugs seem to like it too. To perk up the garden for the cooler months, here are the plants we added:


Pentas lanceolata in red...

and pink.


Lavendula pinnata

And of course, plenty of milkweed, both red and yellow flowering.

It's nice to have a backyard full of color again, and on warm afternoons the butterflies are definitely enjoying it. It's good to be getting My Florida Backyard back into the swing of things again!

Black and White

The rainy season officially started on June 1, and we ushered it in here in My Florida Backyard with almost three inches of rain. After watching almost of all TS Beryl's rain go north and east of us, it was wonderful to see our rain gauge fill at last. The plants in the garden seemed to perk up almost immediately, as often happens after a nice rain. We took a little stroll around the yard to check things out, and discovered this random passionvine that we don't remember planting...


...at least not in this exact spot. We do have some about 25 feet away, and passionvines are definitely known for spreading underground and popping up in new places. This one is Florida's native Maypop (Passiflora incarnata), which is so aggressive that many people consider it a pest in their gardens. We don't mind it, because it generally gets eaten so quickly by Gulf Fritillary caterpillars that it doesn't have time to cause problems. Interestingly, though, it wasn't Gulf Fritillary caterpillars we discovered on the Maypop...


... it was Zebra Longwing (Heliconius charithonia) caterpillars! This was pretty exciting, because this is the first time we've documented Zebra Longwing caterpillars in our yard. I raise them at work all the time, and I've written about them on My Florida Backyard before, but it's so fun to have them here naturally.


These are one of my all-time favorite Florida native caterpillars. The stark black-and-white coloration, the crazy long (but completely harmless) spikes, the reddish color on their legs and prolegs - they're just really fascinating. These caterpillars are just about full-grown, and soon will pupate into chrysalis - also some of my favorites, as they look like tiny upside-down bats.


Zebra Longwing butterflies are actually pretty rare sightings in our yard; we don't remember seeing one here in several years. They're obviously around though. They have a great affinity for firebush as nectar plants, and this passionvine just happens to be climbing up one, so this is a perfect corner of our garden for them. We'll know now to keep our eye out for them, both as caterpillars and adult butterflies.

Strange Things

Happy Spring! Although it's been feeling like spring since about mid-January here in My Florida Backyard, we're definitely enjoying the longer days and the recent time change allowing us more time outside in the evenings. A few extra minutes to take an evening stroll keeps us from missing the little things that are happening, like the strange and fascinating rue flowers that are blooming now.


As we've noted before, rue as an herb doesn't play much of a role in most cooking these days due to its sharp, fairly unpleasant scent and flavor (Ruta graveolens literally means "Bitter herb with a strong, unpleasant smell"), but we love having it in the butterfly garden, where both Black Swallowtails and Giant Swallowtails use it as a host plant. Interestingly, this herb is apparently quite admired in its native Southeastern Europe, where it's the national flower of Lithuania and is frequently carried in bridal bouquets. To each their own, I guess.


Strange flowers and a stranger smell... rue certainly doesn't work in everyone's garden. But My Florida Backyard is a wildlife garden, and rue is a wildlife plant, so we like it. What's the strangest thing growing in your garden, and why do you grow it?

Mellow Yellow

Fall is the time of purple and gold in My Florida Backyard, and one of the brightest patches of yellow comes from the Winter Cassia (Cassia bicapsularis syn. Senna bicapsularis). This shrub provides a bright burst of color from now through the first frost with its unusual flowers, but that's not the only way it provides gold in the garden. You see, cassia species are host plants for sulphur caterpillars of several varieties. Normally, these caterpillars are the same green shade as the leaves they eat. But when the flowering season arrives, the caterpillars immediately begin to dine on this delicacy, and as a result - they turn bright yellow.


The species above is an Orange-Barred Sulphur caterpillar, but Cloudless Sulphur butterflies (shown below) will lay on cassia as well, along with the smaller Sleepy Orange. They generally lay far more eggs than will ever hatch - Winter Cassia is extremely attractive to ants, and while harvesting nectar the ants will also gobble up any sulphur eggs along the way. Fortunately, sulphur butterflies seem to haunt these bushes, laying eggs from spring to first frost, so their continued success is pretty well-assured.


It should be noted that some organizations place Cassia bicapsularis on invasive species lists, but other groups, like the University of Florida Extension, are not concerned and in fact continue to recommend this bush for planting. To add to the mess, C. bicapsularis is sometimes confused with Senna pendula, a similar and possibly more invasive species. You can use your own judgment on whether to include this non-native in your own landscape, but in My Florida Backyard, we feel comfortable enough with this plant to enjoy the incredible benefits it brings to the butterfly garden, including the bright yellow caterpillars of fall.

P.S. Nov. 7: A quick update - here's a good article from FloridaGardener.com with more info about the differences between C. bicapsularis and S. pendula.

Purple and Gold

Northern autumns mean colored leaves blazing the hillsides. Here in Florida, autumn comes in with plenty of color too, and the height of it is just beginning. My Florida Backyard is full of the purples and golds right now that make a Florida autumn special.


The muhly grass (oh, the muhly grass!) is at its peak right now. We write about it every year, because we wait for it and love it just as much every year. What an amazing native grass!


The Winter Cassia (Cassia bicapsularis) is beginning to bloom too. After spending the summer being visited by bright yellow sulphur butterflies to lay eggs, the cassia seems to takes its inspiration from them, putting forth gorgeous gold flowers that will turn the caterpillars a brilliant yellow as the fall progresses.




There are plenty of other fall colors around the yard (Beautyberry and Carolina aster to name a few), but they'll have to wait for another post, because the purple and gold of the muhly and the cassia are all we really seem to need today.

Don't Be Shy

Here in My Florida Backyard, we're lucky to live on a stormwater drainage pond, part of a huge stormwater management system designed to prevent flooding and filter out contaminants before they can drain into the groundwater. This pond also adds a wetland aspect to our environment, bringing in wading birds, alligators, and water-loving plants we wouldn't have otherwise. We love to check out the shoreline for new sightings, like this cute little wildflower we found the other day.


We pulled out our Wildflowers of Florida Field Guide and found it on the first page of the "yellow flowers" section. It's Shyleaf (Aeschynomene americana), a native plant found in wetlands throughout Florida. It grows about 2 feet by 2 feet, in a rather feathery fashion that reminds us of Partridge Pea.


In fact, both Partridge Pea and Shyleaf are in the Pea Family (Fabaceae), as you can pretty easily tell by looking at the flowers, and by the fact that it spreads by seeds from pods. It prefers moist soil, so it's often found along the edge of lakes and rivers. As you might have guessed from the name, Shyleaf folds up its leaves when touched, and it's a host plant for the Barred Yellow (Eurema daira) butterfly, a fairly small pale yellow butterfly with a green caterpillar.


It's always fun to find a new plant in and around My Florida Backyard, and when it's a native wildflower, that's even better. When you keep your eyes open, you never know what you might find!

Hidden Away

We know we've been a little remiss with the blog posts here on My Florida Backyard lately. It seems we're in the doldrums of late summer, with not much happening. We've started clearing out some of the overgrowth lately, though, getting ready for some fresh fall plantings whenever that cooler fall weather arrives. Recent rains and winds had beaten our amazing forest of Partridge Pea down, so we removed nearly all of it, leaving just a few plants to provide seed for next year. The butterfly garden is very bare without it.


On the plus side it gave us a chance to rediscover some of the plants tucked away underneath it all. The dotted horsemint (Monarda punctata) is even more prolific than we had realized.


Some 'Coral Nymph' Salvia coccinea is doing pretty well under there as well, along with some purple Lantana montevidensis.



Nearby, after pulling some overgrown grass and other weeds, we found some brilliant pink Pentas lanceolata, along with an orange zinnia that must have popped up from seed.



So, we found some hidden treasure in the garden, which was nice. Oh, and don't worry about the sulphur butterflies who were using the Partridge Pea as host plants - they've got plenty of room on the nearby Cassia bicapsularis for their caterpillars!

Skipping 'Round the Garden

Not all butterflies are big and colorful. Some are small and need to be seen up close to be truly appreciated. Case in point: the Long-Tailed Skipper (Urbanus proteus). This diminutive butterfly is only a couple of inches in size, and seen in flight might appear to be a drab brown. But take a closer look - there's more than first meets the eye.


Long-Tailed Skippers lay eggs on a variety of plants in the pea and bean family (Fabacae). In the past, we've had Long-Tailed Skipper caterpillars on Hairypod Cowpea (Vigna luteola) and Creeping Beggarweed (Desmodium incanum). We've grown green beans and peas for them, too. This year, we have a new "volunteer" host plant for these skippers, Dixie Tick Trefoil (Desmodium tortuosum), a non-native that has naturalized in the southern US. A seed from this plant most likely hitched a ride home from the butterfly garden where I work, and has taken hold and grown... and grown... and grown. This plant is now well over six feet tall, and the leaves are kind of like condominiums for skipper caterpillars.

Skippers are leaf-rolling caterpillars. They use silk to pull the leaves around them to protect them while they eat. The leaves of D. tortuosum are soft and textured in a way that actually makes them stick to each other very easily, rather like Velcro. Perhaps this helps the caterpillars with the rolling?

Long-Tailed Skippers lay their eggs in stacks several high. We managed to catch this one in the act of ovipositing the other day - if you click the picture to enlarge it and look very closely, you can see the eggs she's already laid on the leaf at the end of her abdomen.


The light wasn't great, but we didn't want to disturb her, obviously. We did flip over the leaf and get a better shot of the eggs themselves when she was done.


Long-Tailed Skipper caterpillars have fun little heads, shaped almost like the peas and beans from their host plants. This caterpillar looks similar to other skipper caterpillars, like the Dorantes Skipper, but is easy to distinguish due to its bright orange hind end.


When ready to pupate, the caterpillar rolls itself up one final time for a safe place to transform into chrysalis. The chrysalis of the Long-Tailed Skipper is coated in a powdery substance that is a actually wax (click here to see a picture). After a couple of weeks, they emerge as butterflies to begin the process again.


Big or small, the butterfly and its life process is fascinating. We're so glad to have such a wide variety of species in all parts of their life cycle here in My Florida Backyard!

Wild Turkey

We were pleased to find a few patches of what has to be the best-named wildflower out there growing near the lake in My Florida Backyard. It seems like such a nondescript little plant to have such a silly and fun name, but there it is... Phyla nodiflora, commonly known as "Turkey Tangle Fogfruit", or sometimes just Frogfruit.


This little native plant is actually pretty important for butterfly gardeners - the Common Buckeye, White Peacock, and Phaon Crescent all use it as a caterpillar host plant. Smaller butterflies nectar on the little purple and white flowers too, so a patch or two of this can be very valuable.


As for the fun and crazy name of this plant... well, that's anyone's guess. No amount of searching has turned up any clue as to who gave this wildflower its common name, or why they chose that of all names. If you have any clue, please drop us a comment. We really hate unsolved mysteries in My Florida Backyard!

Flying Dutchman

When Calico Dutchman's Pipevine (Aristolochia littoralis) flowers, you really can't miss it. The blooms are the size of dinner plates, and up close the smell is fairly unpleasant. Still, the blooms are fascinating in color and shape.


Honestly, we probably shouldn't have this vine in our yard. A. littoralis is invasive in Florida (it's currently on the FLEPPC Category II list). We keep it around for the Polydamas Swallowtail caterpillars to feed on. However, because it's from South America, it's actually toxic to the Pipevine Swallowtail caterpillars who also can accidentally lay on it.

Fortunately, it's easy to tell the eggs of the two species apart, so by watching the vines carefully for eggs, we can remove the red ones of the Pipevine ST to the native A. tomentosa that we also grow. (Polydamas eggs are yellow.) If you're not willing to take the time to do this, it's probably best for butterfly gardeners to eliminate A. littoralis from the yard to avoid harming our native butterflies.
