Strelitzia reginae is a bold structural plant, which forms large evergreen clumps of stiff leaves growing up from the base. The grey-green banana-like leaves grow about 1,5 m in height and the flowers stand above the foliage at the tips of long stalks. Mature plants are very floriferous with flowers in autumn, winter and spring.
The structure and pollination of the flowers are rather interesting. The hard, beak-like sheath from which the flower emerges, is called the spathe. This is placed at right angles to the stem, which gives it the appearance of a bird's head. The flowers, which emerge one at a time from the spathe, consist of 3 brilliant orange sepals and 3 bright blue petals. Two of the blue petals are joined together to form an arrow-like nectary. When the birds sit to have a drink of nectar, the petals open to cover their feet in pollen
