You are into a new learning experience! Here are a few tips... 1. Winter gardening is fantastic. Your local box stores should have pansies, Bright lights swiss chard, kales, snap dragons, parsley. Plant them all. Sow sweet peas next month. Buy the cheap spring bulbs at box stores now, plant them for bloom next spring. Treat them as annuals. Also, at box stores you will find chrysanthemums that have bloomed available at reduced prices. Buy them, plant, cut back for heavy bloom next spring. They blossom spring and fall in your zone. 2. The various southern gardening books are useful for flowering shrubs. Suggest that you purchase an expensive book titled A-Z ENCYCLOPEDIA GARDEN PLANTS by the American Horticultural Society. Great reference book which you will turn to often. 3. Hilton Head, Charleston and Beaufort have open garden tours in the spring. Most helpful to see what others are growing. They are usually well advertised in the newspaper. 4. There is a whole world of roses to explore. Ditto Camellias. You will find the The Greenery Nursery on Hilton Head to be very helpful in guiding you plus they carry excellent plant selections. Take your time learning, visiting and talking with gardeners. Years of fun growing ahead of you.

I don't know exactly where to find the site but I know what you're talking about. You might want to just type "flower pot light" (or light) in your web browser line and see what you come up with. Sal
