Aristolochias are also known as the “Dutchman’s Pipe” or “Pelican Flower.” The five unusual varieties that we grow have been called “outrageous, exotic, botanical wonders.” Their pollinating mechanism is unique because Aristolochias give off a scent which attracts flies. When a fly goes into the tube and chamber, it bangs around inside trying to get out, thus pollinating the plant. Aristolochia gigantea and A. gigantea ‘Brasiliensis’ give off a lemon scent.

• If outside as summer plants, prune back severely for winter or prune when growth is excessive.
• Warm temperatures and full sun are needed for successful flowering.
• Trellis or stake and give lots of room to create your own mini tropical jungle.
