This member of the Bignoniaceae
family was originally described by Carl Linnaeus in 1753, and latest
named by Alwyn Howard Gentry in 1973. It is found in Mexico from
Mexico on, down to Argentina and the West Indies. It has later been spread to
similar climates i.e. Australia. It prefers a well drained and rich
soil, lots of water and some to lots of sun. The tubers will grow up
to three centimetres in diameter, the vines can reach 15 meters or
more. The flowers are bright yellow, and the plant can be reproduced
both by seeds, cuttings and tubers. |
