Pick Up Only

Common Name: Black Bean Tree
Botanical Name: Castanospermum australe
Origin: Eastern Australia

The Black Bean Tree is a striking Australian native known for its glossy, deep green foliage and naturally upright growth. Also called the Moreton Bay Chestnut, it can develop into a large tree outdoors but makes an attractive young indoor plant when provided with bright light and suitable conditions.

Its lush foliage brings a tropical, architectural feel indoors, making it a beautiful choice for adding height and greenery to homes, offices and larger spaces. As it matures, the plant can develop a strong woody trunk and impressive tree-like form.
