The lucky bean plant (Castanospermum australe), also known as Moreton Bay chestnut and Queensland Black Bean, is a tree native to Australia that is often grown as a houseplant. It has glossy, deep green leaves and develops reddish-yellow blooms during spring and summer. The blooms are followed by large seed pods that are reminiscent of beans, which is where this plant gets its name. The lucky bean plant is hardy in USDA Plant Hardiness Zones 9 to 12 and is grown indoors in cooler regions.
Fill a growing container to within 1 inch of its rim with potting soil. Place the lucky bean plant into the soil at the same level it was previously growing. Replace the soil and tamp down. Add water until the soil feels very moist but not soggy.
Place the container in a location that receives full to partial sun. The container can be placed outdoors during the warm months of spring and summer and taken inside again before the first fall frost.
Soak the soil well at each watering and allow it to become dry to the touch before adding more moisture. In early fall and throughout the winter months, add just enough water to keep the soil from drying out completely.
Fertilize once each week with a water-soluble fertilizer during spring and summer. Stop feeding the plant in fall to promote dormancy.
