For the brave home gardeners among us, Florida's environment offers a host of challenges with its scorching heat, patchy rainfall and that sandlot in the front yard charitably called "soil." Add knee-high weeds and four seasons that seem to blend into one hot and humid swelter, and even the greenest thumb may be tempted to pour wet cement over the whole mess and be done with it. Ah, but not so fast, do-it-yourselfer; help is on the way. The Pinellas chapter of the Florida Native Plant Society presents Real Florida Landscapes — Workshop and Sale at Weedon Island Preserve, an opportunity for locals to learn about landscaping with environmentally-friendly native plants, which conserve water, limit the need for pesticides (always a good thing) and don't require a whole lot of maintenance. (Do I have your attention now?) The society also has some native plants for sale and offers an info session on how to care for them. This event is free and open to the public, so bring the whole family. Sat., Sept. 23, 10 a.m.—noon, 1800 Weedon Drive N.E., St. Petersburg, 727-453-6500.
