Talk about your symbiotic marketing! You've just toured the verdant Missouri Botanical Garden. There's a name for your condition: You're plant-crazy, convinced that you too will soon be a master gardener. On your way out, you decide to stop off at the gift shopjust to browse, of course. By then it's already too late. Before you know it, you're scooping up bonsais and orchids, pruning shears and fertilizer. And that's just in the first few steps. Wade deeper into the Garden Gate Shop and you'll find a handsome collection of books to make your plant education bloom, plus hummingbird feeders, colorful skirts and imported backpacks. Not shopping for yourself? Head over to the children's section to find plantly merch for the small set. The Garden Gate Shop also offers a fine selection of jewelry, and during the Dale Chihuly hoop-dee-doo even carried a few of the glass master's creations.
