Actually the only species in the genus Castanospermum, this little evergreen plant can grow to become a large tree! Being native to Australia, it’s evolved to thrive in some of the harshest environments, including your home.
As the plants mature, they’ll begin to flower in the summer. Blooms are typical of those in the pea family and are a vibrant orange/yellow color. Size can be controlled by regular pruning, making these plants suitable for a semi-large bonsai in time.
