The lucky bean plant is also known as a black bean plant, Castanospermum australe and Australian Moreton Bay chestnut tree. In autumn, the tree produces sprays of small red and yellow flowers. During the following spring, large, round pods are produced. The pods split into two parts and reveal three to five large seeds that resemble beans. Native to the coastal rain forests and beaches of Australia, this tree can be grown outdoors in tropical climates or indoors as a houseplant in more moderate climates. Proper care involves placement, soil medium, sunlight and moisture.
Select an area to plant the tree. Moreton Bay chestnut trees can reach from 26- to 66-feet tall and have a 13- to 26-foot wide dense, umbrella-shaped canopy of dark green leaves, and so it is ideal to place the tree in an area where it has enough room to spread its branches. In addition, the space should offer full sun to light shade. This applies to potted trees, too.
Plant the tree seedling in the ground or in a large container. If planting in a container, fill the container with a combination of slow-release fertilizer and store-bought potting mix. If planting outdoors, dig a hole twice the size of the seedling's root ball and place the tree inside. Fill the hole with a combination of potting mix and slow-release fertilizer.
Water the tree regularly, keeping its soil moist at all times. Do not over-water, however, or root rot may result.
