Once upon a time, South Carolina was blessed with 36 species in the genus Aster, beautiful plants every one. Back then, you were most likely an Aster if Joining or Renewing: you were a perennial herbaceous forb, with rhizomes, composite flowers, and numerous white to blue ray flowers. Fortunately all those species are still here, Some Critical Points but are traveling under other names now.

See on pg 4 updated in an Excel spreadsheet that Asters is stored safely off-line. This database information is distributed only to a small list of responsible officers. The system recognizes that not everyone has access to, or interest in, computer communication. Thus, we make available an on-line membership application and renewal feature, as well as paper forms that serve the identical purpose (www.scnps.org and click Membership). The paper forms can be downloaded and printed for use. Application and renewal forms have to find their way to the appro- priate Society officers. A paper form should be mailed (with check for Figure 1. Important parts of a typical aster flower head. Note: involucral bracts are also called phyllaries.

New members receive a new member welcome The Plight of the Honey (and other) Bees Bill Stringer, SC Native Plant Society We are seeing a surge of reporting on the plight of honey bees and native bees that serve as pollinators for many of our food crops. Most vegetable, berry and tree fruit crops depend on bees to carry out the pollination required for producing the tomatoes, blueberries and apples, etc. that we eat. What can we, as rural and urban homeowners, do to help stem this decline? The populations of these important facilitators of food crop production are plunging due to a number of causes, some identified, and some still clouded in mystery. Pest mites, fungal and bacterial diseases, and certain insecticides that are widely used to control crop pests have all been implicated. Another factor with potential to have large negative effects is the current increasing reliance by farmers on wind-pollinated crops such as corn and wheat. These plants rely on wind to spread their pollen, and thus don’t produce nectar that bees harvest for energy and honey production. Areas with a large proportion of the crop acreage devoted to these wind-pollinated crops will have a low value as bee Honeybee on white clover (Trifolium repens). habitat. But most of us are not farmers, so we don’t make decisions on which crops to grow, or which pesticide to use on millions of acres. So what can we do? A lot, it turns out. You probably have white clover in your lawn; most lawns do. Ever notice all those bees flying around the clover flowers when you are mowing? They are after the nectar and pollen 2 South Carolina Native Plant Society • March 2014 from those flowers, and are very happy to find your “weedy” white clover. Yet a significant number of home owners apply an herbicide to their lawn in a futile effort to eradicate the clover. My suggestion?: leave the clover, and supplant the pride in a uniform, dark green grass lawn with the knowledge that you are helping our great friends the pollinators. You might say, ”Well, I don’t have a vegetable garden, so why do I need bees?” It turns out that honeybees will easily fly as far as 3 miles in search of pollen and nectar. So you can help feed bees from across town. And your berry-bearing shrubs that songbirds congregate on in winter? They need bees as well. Another easy thing we can do is to not be so quick to mow our “edges” to control “unsightly” flowering plants that grow there. Managers of roadside rights-of-way can make a huge contribution by reducing the frequency of mowing roadsides. I am an ardent admirer of native sunflowers, milkweeds and other wildflowers that grow naturally on our roadsides. In Honeybee on butterfly milkweed Asclepias( tuberosa) particular, by early July, I know where every butterfly milkweed plant can be found along the roads that I frequent. If you’ve ever looked closely at a milkweed or sunflower in bloom, you’ve seen how many honeybees, native bees and butterflies are working the flowers. Yet, two to three times during a growing season, I will travel those roads, and note with sadness that the mowers were there yesterday, and all those blooms are gone. Where are those bees going to find a replacement food source for today? With luck they can find a white clovery lawn nearby? Well, maybe not. We could reduce the number of mowings, reduce the cost of right-of-way maintenance, and improve the lives of our pollinator friends.
