The Southern festoon, a rare butterfly species of European importance, is bound to the warmest regions of Slovakia. The development of its monophagous caterpillars takes place on the Aristolochia plant. The restoration of these plants by direct sowing is possible, but time-consuming. However, they reproduce very well by rhizomes. When transplanted to new sites, plants propagated and planted in this way grow vigorously. In the initial stage after planting, however, they need to be protected from animals by a fence. These plants will feed the butterfly caterpillars in the natural reserve Beckovské Skalice.
