Tita Hipol is one of those people with such a passion for gardening that for her it's not enough to make her own yard look beautiful. She has to propagate more plants, fill more pots, get others to appreciate the flowers she loves. For years she simply gave plants as gifts to friends and family members. But then someone suggested she charge something to make up for all the money she was pouring into greenery. The result: Tita's Flower Patch. Really it's her home, located on an out-of-the-way street on the edges of Columbia City. In front, in back, at the side?everywhere are little flower-filled pots selling for less than half what you'd pay at a regular nursery. Not an experienced gardener yourself? Hipol will be happy to while away the time telling you how to take care of your new find. ?Nina Shapiro 3827 S. Findlay St., 227-1193
