Other than orchids, the gesneriad family most likely offers the widest range of flowering houseplants. The best known members include African violets, gloxinias, lipstick plants, and cape primroses. One of the best overviews of this family is The Gesneriad Reference Web. This is one of those labor of love Web sites by an individual, in this case a gentleman named Ron Myhr. The site has at its core over 1,500 images of gesneriad species and cultivars, along with brief descriptions. In addition, you'll find general culture information, antique prints of gesneriads, articles about gesneriads, and links to other related Web sites.

Window Plant Stand
If you have only one or two windows that receive light good enough for houseplants, consider maximizing the space with a window plant stand like the one available from the NGA Garden Shop (http://www.store.yahoo.com/nga-gardenshop/14-1108.html). Basically, it's a light garden without the lights. It provides four stories (and almost 8 square feet) of growing space, in sturdy plastic trays. The stand is constructed of aluminum and has smooth-rolling casters. The dimensions are 25 inches wide by 12 inches deep by 70 inches high, and it costs $139.95.
