Tecomanthe

Tecomanthe is a genus of 5 species of tropical or subtropical forest lianes in the family Bignoniaceae. They have attractive trumpet-like flowers and glossy leaves. They are native to Australia, Indonesia, New Guinea, New Zealand, and the Solomon Islands.


Species
Tecomanthe speciosa - A solitary plant of Tecomanthe speciosa or the Three Kings Vine was first discovered on the Three Kings Islands, 55km off the northern tip of New Zealand, during a scientific survey in 1945. No other specimens have ever been found in the wild. Tecomanthe is a tropical genus not otherwise represented in New Zealand. Four other species of Tecomanthe occur in Queensland, Indonesia, New Guinea, and the Solomon Islands.
Tecomanthe speciosa is a vigorous twining climber growing up to 10m in height. The glossy, thick compound leaves consist of up to five leaflets. In autumn or early winter it bears long cream-coloured tubular flowers that emerge directly from the stem in large clusters. The flowers appear to be adapted to be pollinated by bats, despite the fact that bats are not part of the present-day fauna of the Three Kings Islands (though they may once have been present). Nevertheless, the flowers of plants growing in cultivation are readily pollinated by a large number of native and exotic birds.
After a decade, the plants raised by the horticulturists finally set seed, and Tecomanthe speciosa has subsequently become popular in New Zealand gardens as a vigorous climber of tropical appearance. The plant requires warm conditions, and is very sensitive to frost, suffering damage if the temperature drops below -2C. It is readily grown from cuttings, layering and from seed. Seed must be sown fresh and should germinate within two weeks. The seedlings grow vigorously, and may flower within two or three years. Plants grown from cuttings may take up to five years or longer to flower.

Tecomanthe volubilis is endemic to New Guinea and has rose-pink flowers. It grows in mossy forests at altitude, and will grow in warm temperate conditions.
