Overview

The lucky bean plant (Castanospermum australe), also referred to as black bean plant, is actually native to Australia. It has attractive, glossy foliage and develops small orange and yellow flowers in spring and summer. The flowers are followed by large pods that contain bean-like seeds, the source of the tree's common name. The lucky bean plant can be grown in a container or planted outdoors in warm regions, where it can reach heights of more than 20 feet.

Step 1

Fill a planting container, with holes for drainage to prevent root rot, three-fourths of the way with potting soil. When planting the lucky bean plant in the yard or garden, select a site, ideally with full sun, and amend the soil with a mixture of perlite and peat moss if the soil seems prone to packing when moist.

Step 2

Plant the lucky bean plant at the same depth as it was growing in its original container. If planting outdoors, make the planting hole a fraction larger than the root ball of the plant. Tamp the soil down firmly to remove air pockets. Water until the soil is thoroughly moistened.

Step 3

Continue to water regularly. Thoroughly saturate the soil at each watering and do not water again until the top layer of soil feels dry to the touch.

Step 4

Fertilize each week during the growing season with a water-soluble fertilizer mixed according to package directions.

Step 5

Examine the stems and leaves often for signs of pest infestation or disease. Treat promptly with an insecticide or fungicide if necessary.

Step 6

Move the lucky bean plant indoors before the first frost if it is planted in a container.

Tips and Warnings

  • Both the seeds and leaves of the lucky bean plant are poisonous to livestock. Do not plant this tree within 30 feet of natural gas lines, sewers, home foundations or swimming pools because the large roots can cause damage as the tree grows.
