Aristolochia elegans is an evergreen vine with unusual flowers and heart shaped leaves. Calico flower is native to Brazil.
Blooming Time: Flowers are produced throughout the growing season. Flowers look almost like an old night cap or like pipes with elegantly curved stems.
Culture: Aristolochia elegans like to grow in a light and airy place, but not in direct sunlight. Keep summer temperature from 68-78 degrees and winter temperature above 50 degrees. Water regularly during the growth period, once or twice a week. Water no more than once a week during winter. Fertilize with a balanced fertilizer every third watering throughout the growing season. Calico flowers grow best in rich, well-drained soil. Young plants need to be repotted every other year, older plants every 3-5 years. Cut back in fall after blooming.
Propagation: Aristolochia elegans is best propagated by cuttings, but it can be grown from seeds. Take cuttings in fall when flowering is nearly completed. Softwood cuttings should be 4 to 5 inches long. Treat with rooting hormones and place them in a fast draining propagating mix. Put them in a warm place, preferably with bottom heat. Softwood cuttings must be kept moist. Start seeds by soaking in water for 48 hours and surface sow them. Seeds need light to germinate.
Aristolochia elegans was featured as Plant of the Week April 2-8, 1999.
