This grower is sure of this plant identification.
This is an example of a plant I have for sale. I have smaller and larger ones available.
Chines dwarf banana, Golden lotus banana
Musella lasiocarpa (Chines dwarf banana). This ornamental banana grows trunk-like pseudostems and large, upright grey-green banana-like leaves. Throughout the summer the plant typically bears 2-3 large, ochre yellow, lotus-like flowers that grow from the top of the stems. In warmer climates the flowers are followed by small inedible banana fruit.
As with other bananas, plant where leaves will not be damaged by wind. Over-winter in frost-free conservatory or greenhouse. Keep soil moist but not wet.
Grown for their dazzling flowers and tropical impact. The flowers can lust up to 6 months.
