When I walk around the garden every day I take a little inventory of how things are growing, what is flowering, and am always on the lookout for new bugs I haven’t seen before. This past week I was pleasantly surprised by what at first I thought was a bee with a long mouthpart (proboscis), but soon realized it was not a bee at all!
This small, flying insect buzzed up to purple flowers on several plants in my garden. The body was covered in golden hairs with some black showing through giving it that distinctive bee look. The proboscis was so long in proportion to the rest of the insect that it reminded me of the beak on a hummingbird. Still thinking it was a bee of some kind I started trying to get a picture and that is when I saw the telltale antennae and eyes that clued me in that this was not a bee at all, but rather some type of fly.
So, what was this strange looking insect? It is a bee mimic commonly called a bee fly (Bombylius spp.). The bee fly not only looks like a bee, but it takes advantage of native bees to support its young. The female bee fly watches where a ground dwelling solitary bee makes her nest and as she forages for pollen to feed her young the bee fly drops an egg nearby. After hatching the bee fly larva makes its way into the real bee’s nesting chamber and eats the pollen provisions then eats the bee larva. Since solitary ground dwelling bees tend to aggregate in similar suitable locations, I can only guess that the bee fly’s clever disguise prevents it from drawing attention as a threat to the hardworking bee.
Since so many people are asking questions about alternatives to lawns, I wanted to provide an update on the growth of Powderpuff Mimosa (Mimosa strigillosa) in my own home lawn. Almost a year ago, I made a video about using this native plant as a companion plant in an existing North Florida lawn. You may view the video if you missed it. https://www.youtube.com/watch?v=0NxKdN74jVs. Almost a year later, I am very happy with the spread of this plant through the lawn area and the beautiful blooms that offer interest in the lawn.
If you are considering this plant as a lawn companion in North Florida, realize that the foliage will often die back with a freeze. I did have a couple of small bare spots through winter. I could see the running stems of the mimosa but it did not have any foliage. That is one of the reasons why the plant is best as a companion plant instead of the main lawn feature in North Florida. You must also be considerate of the neighbor’s property if your planting area is on the border. Talk to your neighbor first about the strong possibility of the mimosa growing across a property line and if that is ok. My lawn area is bordered by many feet of mulched beds so that is not an issue for my planting. Like I mentioned in the video, I do have to edge the mimosa at the mulch beds where I don’t want it growing into other plants and groundcovers.
One last practice that I do have with the mimosa is hand pulling any weeds that I don’t want growing in it. I have a few rushes and some of the annual chamberbitter that will pop up. Some of the traditional weed management techniques that are acceptable for turfgrasses, will not be appropriate for mimosa. Consider carefully if you will be able to tolerate a few weeds or if you can commit to hand pulling a few here and there.

If you determine that your lawn or landscape is suitable for Powerpuff mimosa, you may look for plants at a native nursery. We have a couple of good native nursery options in the western Panhandle and you may be able to find plants throughout North Florida. There is also seed available through wildflower cooperatives. If you have a friend with some, you can always start a tray from a few cuttings too.
UF IFAS Extension Escambia County was recently able to offer a native tree and shrub giveaway to our community. A county partner had some grant funding remaining and chose a nice selection of plants grown by a local native nursery. After seeing the plant selection, I was really excited that a few participating homeowners had the opportunity to take home one of my favorite native plants, the Sparkleberry, Vaccinium arboretum.

Twenty-three years ago, I saved a sparkleberry on my new home lot because I loved this native tree. It has interest in all seasons in my opinion, including flowers, small fruit for wildlife, attractive bark, and an interesting shape as it matures. It has been a slower growing tree than others in my yard but I have enjoyed watching the tree develop its form and the bark develop the beautiful flaky cinnamon-brown look.

The small tree is now about 12 feet tall and has never had any issues in the sandy, well drained soil. It can tolerate some moisture as long as the soil drains well. A grouping of trees from my neighbor’s lot keeps the plant in partial shade and we can often find sparkleberry specimens in the filtered light of woods. It can tolerate a sunnier location if that is the spot you have available for a small tree.
In addition to our enjoyment of this native tree, pollinators and other animals will appreciate the flower nectar, pollen, and berries. If you have a native nursery close to your home, be sure to ask for your own Sparkleberry if your site is suitable.
Two years ago, the Escambia Master Gardener Volunteers were gifted with the flowering perennial Sweet Almond bush (Aloysia virgata). It has quickly become a favorite plant of volunteers and garden visitors due to its many attractive features.
Although, Sweet almond bush is not a Florida native, it is Florida-friendly plant for zones 8b -10b. Plants grow very large, from 6-10 feet with branching that can spread out in all directions. In North Florida, plants can be damaged by a freeze but either return from the base or from growing points higher on branches.
One of the best features are the fragrant white flowers spikes that will be present late spring through fall. Many types of pollinating insects will be attracted to the flowers, although sometimes flowers are too high on the plant for many of us to get a good look at pollinator details.

We have plants both in full sun and partial shade that are performing well in the Escambia Demonstration Gardens. Plants do receive water when rainfall is lacking for about 5-7 days (or all of August this year in the Northwest Panhandle). You can shape your plant with a little light pruning during the growing season to keep branches a little more in bounds. Don’t forget to start a few new plants from these cuttings and then share a low maintenance plant with your neighbors.
Salvias are a popular group of plants for attracting pollinators and adding lots of color to the landscape. A unique salvia that offers velvety flowers is the Mexican bush sage, Salvia leucantha.
In our heat, Mexican bush sage can tolerate partial shade and likes average water with well drained soils. Plants will not overtake a spot only growing 2-4 feet. The velvety portion of the flower is a purple calyx with the flower petals emerging white or purple. Flower stalks will extend above the foliage to be available to many bees, butterflies, and hummingbirds.

During cold winters, plants can die back to the ground but often return each spring. It is always good to take a few cuttings for new plant starts just in case your plant dies back from heavy rains or drought conditions.
Mexican bush sage can be an accent plant in your garden or used in a small mass of 2-3 plants. Consider adding it with contrasting textures and colors so later summer flowers are easily visible.
