From Stump to Butterfly Haven
The 2004 hurricanes damaged a sweet gum tree in the middle of our back yard and we had to have it removed. Back then it was an eyesore, but now it's a beautiful butterfly garden.
First we cut away all the turf around the stump until we had a circle that was about six feet in diameter, then we dumped several wheelbarrow loads of pond muck on top of the stump. (We were cleaning out the pond out front.) Then we covered the muck with a few inches of sandy soil. The resulting mound was about two and a half feet taller than the lawn. Now, four years later, I'm pretty sure the old stump has rotted and is providing nutrients for our butterfly island.
That first year I planted some mystery tubers that the former own had planted in with the canna lilies (Canna X generalis) on the side of the house. I finally figured out that these were hidden ginger lilies (Curcuma zedoaria). The tropical-looking ginger lily leaves are three feet tall, so they provide a backdrop to everything else that's planted there, and as you can probably see, one canna snuck in with the gingers. These big leaves die back in the winter.
I've tried several types of plants on the mound with varying degrees of success, and each year we remove a little more of the lawn so the mound is expanding. I've also added compost and mulched the mound to keep some of the weeds at bay. Last year the zinnias (Zinnia elegans) grew very well there and I wrote about them in an earlier article, Jewels of Summer. Some soft rush (Juncus effusus) grew on one side of the mound, and I planted some perennial Maximillian sunflowers (Helianthus maximiliani) on the top of the mound that have seeded themselves so there are now several plants. Last year, the wild aster (Symphyotrichum spp.) was a little too wild, so I've pulled out most it.
This year I replanted zinnias and have added several native blazing star bulbs (Liatris spicata). I also planted some red hot pokers (Kniphofia uvaria), which are native to South Africa, but they haven't really taken off. Most of the plants I've purchased were chosen for their habitat value for butterflies and hummingbirds in the garden. While the soft rushes don't add much to the butterfly habitat, they volunteered along the lower edges of the mound and provide a year-round vertical structure.
One reason for trying a broad selection of perennials is to have an easier and more dependable way to provide good variety for the butterflies and hummingbirds. Each year they should continue to grow without my intervention. While zinnias are easy enough to grow, each year they need to be replanted. I'd like to get to the point where all that's required is a quick mulching each year for our butterfly and hummingbird paradise.
I hope you will turn an ugly (or hard to maintain) piece of your landscape into your own butterfly habitat. I think you'll find it rewarding as we do. My words don't do justice to the fluttering beauty on butterfly island from April to December.
* You can tell that it's a female eastern tiger swallowtail because of the blue spots on the lower sections of the wings. The male is yellow and black, too, but doesn't have the blue. The female could also be mostly black with the blue areas in the same place on the wings. This is called the dark phase and is more common here in its southern range. Maybe some of the dark swallowtail butterflies that I thought were spicebush swallowtails were actually the dark phase of this tiger. Hmm. . . I'll have to look at some of those photos to look for the ghostly stripes hiding in the black.
Ginny Stibolt moved to northeastern Florida in 2004 and even though she's a botanist and lifelong gardener, Florida gardening was a shock. She started writing The Adventures of a Transplanted Gardener columns for the Times Union newspaper in Jacksonville. This is one of those columns archived here on Floridata.com for your enjoyment. Now she's written three Florida garden books published by University Press of Florida: Sustainable Gardening for Florida, 2009; Organic Methods for Vegetable Gardening in Florida with Melissa Contreras, 2013, and The Art of Maintaining a Florida Native Landscape, 2015.
