Red Orchid Bush

Red orchid bushes have red flowers and are bushes, but they are not orchids.

  • ‘Red orchid bushes’ are also known as ‘red bauhinias’, ‘Pride of De Kaaps’, ‘orchid trees’, ‘nasturtium bauhinias’, ‘African orchid trees’ and ‘African plumes’.
  • Red orchid bushes are from the family Fabaceae, which is the family of legumes, beans and peas, and their scientific name is ‘Bauhinia galpinii’.
  • Red orchid bushes are clambering, evergreen perennial shrubs that are native to south and east Africa.
  • Red orchid bushes have flowers 5 to 10 cm (2 to 4 inches) in diameter, with five petals and three large stamens, and are usually red, although pink and orange varieties are also available.
  • Red orchid bushes generally grow to be a height of 3 to 5 metres (10 to 16.4 feet), but may climb higher with the support of other trees.

  • Red orchid bushes are often used as an ornamental in gardens, and they prefer sunny or partly shady conditions.
  • Red orchid bushes are a weed in some countries, including parts of Australia, as the seeds and cuttings are easily grown and spread by garden waste, water and garden trimmings, and the plants can be found on abandoned urban land, forest and woodlands.
  • Red orchid bushes attract butterflies and bees, and the branches have been used for basket weaving and roof trusses.
  • The green leaves of the red orchid bush are shaped a bit like a hoof, and are symmetrical with two lobes.

  • Queensland bottle trees are usually grown from seed, and are popularly used in recreation areas and gardens, often providing good shade.
  • Queensland bottle trees have been traditionally used as shelter, rope and food, particularly by indigenous Australians.

  • Queensland bottle trees have boat-shaped seed pods full of many seeds that have hairs on them that can irritate the skin if touched.
  • ‘Queensland bottle trees’ are also known as ‘Queensland-flaschenbaums’, ‘Narrowleaf bottle trees’, ‘Kurrajong bottle trees’ and ‘Kurrajongs’.
  • Queensland bottle trees can survive up to three months out of soil, and they are therefore commonly transported to various countries, even as a mature tree.

  • A yellow tower cactus can tolerate a mild frost, as long as the cactus is relatively free of moisture content.
