I am surprised that more Georgians are not familiar with the sweetshrub (Calycanthus floridus). Since it bears some of the most fragrant blossoms of any of our native woodland shrubs, you would think that most folks would want it growing in their yard.
The sweetshrub’s blossoms are maroon in color and produce a pleasing aroma that my wife and I are convinced smells like apples. However, some describe the scent as smelling like spicy strawberries. Others inhale the shrub’s pleasing aroma and say it reminds them of a mixture of pineapples and bananas.
Regardless of how you interpret the pleasing odor, the vast majority of us love it. In fact, some people think so highly of it they plant sweetshrubs near their outside doors. This allows them to lean over and take a whiff of the flowers before heading out for the day.
The sweetshrub is also a pollinator plant. Although Sweetshrub blooms generate pollen used by native bees and butterflies, sap beetles are the plant’s main pollinator. However, since sap beetles are small (1.4-inch) and nondescript we often overlook them.
The way in which these beetles pollinate sweetshrub blossoms in a little strange. The fragrant flowers draw the beetles with the scent they emit. Once the beetles land on the blossoms, they crawl down inside the bloom and begin gathering pollen. Here is where this gets odd. When the beetles are ready to leave, they have a difficult time exiting the flower. As such, they often remain there until the flower matures enough for its petals to fold back enough for them to depart. Once they are on the wing, they fly off carrying granules of pollen. When they land on another sweetshrub blossom, they inadvertently pollenate that flower.
Sweetshrub is easy to grow from seed, transplants, and cuttings. While there are cultivars on the market, I have never planted any of them. If you want to be sure you are planting sweetshrubs that produce beautiful maroon blooms, a pleasing apple scent, and pollen relished by pollinators; you cannot go wrong buying plants from reputable nurseries that deal in native plants.
If you are concerned about the plight of Georgia’s pollinators, I urge you to become a citizen scientist and take part in the Great Georgia Pollinator Census. This year’s count will be staged August 20 and 21.
This will mark the third year the census has been conducted. Last year, in spite of Covid-19, 3,755 Georgians representing 124 counties took part in the survey. Their efforts resulted in data collected on almost 82,000 individual pollinators.
The counts have been carefully designed so that Georgians of all ages and skill levels can take part. There is no participation fee and a census requires only 15 minutes of your time. Most counts are held in yards. However, a number of teachers and other youth leaders involve young people in counts held in such locations as school grounds.
The survey is conducted by the University of Georgia’s College of Agricultural and Environmental Sciences. Becky Griffin is the Project Coordinator (email@example.com).
The information gathered is being utilized by UGA researchers for economic valuation studies of pollinators.
