    • Plant Morphology :
      [Others]: Growth Form: Woody perennial vine with a maximum length of 9 – 15 m long. Habitat: Grows along the banks of streams and rivers in dry tropical climates. Occurs at altitudes up to 300 m. This species may become invasive and cover trees. Stem: Young stem is silver and tomentose (densely covered by hairs). Foliage: Leaves cordate (length 15 – 25 cm, width 13 – 20 cm). Upper side of leaves is green and glabrous (smooth and hairless), while the lower side is silver and tomentose like young stems. Flowers: Produces pink or blue to purple, trumpet-shaped flowers (5 cm wide). Flowers are located at the tips and are arranged in inflorescences known as cymes. Fruits: Yellow-brown, dry round fruit (2 cm wide) classified as a berry. Each fruit holds 4 - 6 seeds. Landscaping: Planted in subtropical or tropical gardens for its attractive, large flowers. Can provide shade when trained to grow over a trellis. Makes an attractive cover for long railings.Cultivation: The vine is susceptible to root rot, so plant in soil with good drainage. Prefers acidic soils (pH = 5 - 6). Although mature plants prefer full sun, the seedlings grow best in partial shade. Easily becomes root-bound, so either plant in the ground or provide a very large pot, such as a 55-gallon drum. Grows quickly in Singapore under ideal conditions (3 - 5 cm per day). To promote abundant flowering, avoid pruning the tips. Propagation: Typically propagated by seed. Scarify the seeds to promote germination by cutting the seed coat with scissors or scratching it with a file. Soak the scarified seeds in water for 24 hours before planting. Can also propagate by stem cuttings. Etymology: The genus name “Argyreia” comes from the Latin word “argyraeus” which means silver-colored. It refers to the silver color of young stems and the underside of leaves. The species epithet “nervosa” refers to the hallucination induced by consuming the seeds. Alkaloids known as lysergic acid amides (LSA) are responsible for the hallucinations.
