Aristolochia californica (California Dutchman's Pipe, California Pipevine) This deciduous vine grows best in zones 5-10 and 14-24, and is native to the Coast Ranges and Sierra Nevada Foothills of Northern California. It can cover an 8x10 screen or fence with a little training, or send out climbers 10-15 feet long onto nearby shrubs or trees (these vines do not harm other plants), and can also make a small-scale groundcover. Flowers bloom before leaf-out in winter or early spring. Flowers are reddish-purple and cream and have an unpleasant scent. Leaves are bright green and heart-shaped. Not picky about soil, but does best in partial shade (full sun if in a coastal garden). |
Aristolochia gigantea (Brazilian Dutchman's Pipe, Giant Pelican Flower, Giant Pipevine) This ornamental vine is native to Brazil and has very fragrant flowers. This is a warm-weather loving species and cannot tolerate temperatures below 50 degrees Fahrenheit. Flowers are red to deep maroon and have yellow veining, and the vine reaches 3-6 feet wide and 15-20 feet long at maturity. |
Artistolochia indica (Garudakkodi, Eswaramooli, Sapsada) This vine loves to climb trees in its native range of Southern India and Sri Lanka. It has thick foliage, and is commonly found on forest floor or rocky hillsides. Flowers in this species are much smaller than in others, and they are light yellow to cream-colored with deep red mouths. |
Aristolochia littoralis (Calico Flower, Elegant Dutchman's Pipe) This climbing vine reaches just under 15 feet in length, and has slender, bright green stems. Leaves are green and glossy, and flowers are deep red with white to cream veining. Prefers acidic to neutral soil pH (between 5.5 and 7.0) and is hardy to 45 degrees Fahrenheit. |
Aristolochia macrophylla (Aristolochia durior) (Dutchman's Pipe) This deciduous vine grows best in zones 2-24, and is short-lived in warm-winter areas. Native to the eastern United States, this vine is easily grown from seed. Leaves are deep green, and the vine is fast growing; it will cover a 15x20 foot area in just one season. Flowers bloom in late spring and early summer, and are yellowish-green. Can grow in full sun or heavy shade, and needs average to good soil and ample water. Protect from strong winds. |
Aristolochia rotunda (Smearwort, Round-Leaved Birthwort) Native to Southern Europe, this species of vine produces unbranched stems of foliage and yellow-green flowers with maroon-brown mouths and throat interiors. Flowers bloom from April through June. Leaves are rounded, and flowers are situated at the base of leaves on the vine. |
Aristolochia tomentosa (Isotrema tomentosa, Isotrema tomentosum) (Wooly Dutchman's Pipe, Common Dutchman's Pipe) This species is grown as an ornamental, valued as much for its foliage as anything else. Flowers are small, light yellow to cream-colored, and have deep red to maroon throats. Leaves are large and deep green, and are great at covering trellises or walls. |
Aristolochia watsonii (Watson's Dutchman's Pipe, Southwestern Pipevine, Indian Root, Snakeroot) This species of Aristolochia is native to Arizona through western Texas, where it prefers to live in mountain ranges between 2,000 to 4,500 feet in elevation. These are tough plants to find, and have smaller, arrow-shaped leaves that are maroon with lighter green veining. Flowers are small and maroon to brown. |
