Aristolochia macrophylla (common name: pipevine)
Propagation: Seed - best sown in a greenhouse as soon as it is ripe in the autumn. Pre-soak stored seed for 48 hours in hand-hot water and surface sow in a greenhouse[1]. Germination usually takes place within 1 - 3 months at 20°c[1]. Stored seed germinates better if it is given 3 months cold stratification at 5°c[2]. When large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant out in late spring or early summer after the last expected frosts.
Division in autumn[2].
Root cuttings in winter[2].
Cultivation: Prefers a well-drained loamy soil, rich in organic matter, in sun or semi-shade[3][2], but succeeds in ordinary garden soil[1].
Plants are hardy to at least -10°c[2].
A fast-growing climbing plant, attaching itself by means of twining around other plants, it has been recommended for covering pergolas[2].
Most species in this genus have malodorous flowers that are pollinated by flies[2].
Range: Eastern N. America - Pennsylvania to Minnesota, Georgia, Tennessee and Kansas.
Habitat: Moist, rich woodlands[2][4]. Forests, often on dissected uplands and rugged, rocky slopes; Cumberland and Blue Ridge mountains at elevations of 50 - 1300 metres[5].
Medicinal: The plant contains the antiseptic and antitumor compound aristolochic acid[6].
A decoction of the root has been used externally to treat 'swelling of feet and legs'[7].
A compound infusion of stalk chips has been used in the treatment of 'yellowish urine'[7].
Pollinators: Flies
Soil: Can grow in light, medium, and heavy soils.
Drainage: Prefers well drained soil.
Seed Ripens: Early Fall-Mid Fall
Flower Type: Hermaphrodite
Known Hazards: We have no specific details for this species but most members of this genus have poisonous roots and stems[8].
The plant contains aristolochic acid, this has received rather mixed reports on its toxicity. According to one report aristolochic acid stim
