Strelitzia reginae, commonly known as the crane flower, bird of paradise, or isigude in Nguni, is a species of flowering plant native to the Cape Provinces and KwaZulu-Natal in South Africa. An evergreen perennial, it is widely cultivated for its dramatic flowers. In temperate areas it is a popular houseplant.
The plant grows to 2 m (6+1⁄2 ft) tall, with large, strong leaves 25–70 cm (10–28 in) long and 10–30 cm (4–12 in) broad, produced on petioles up to 1 m (40 in) long. The leaves are evergreen and arranged in two ranks, making a fan-shaped crown. The flowers stand above the foliage at the tips of long stalks. The hard, beak-like sheath from which the flower emerges is termed the spathe. This is placed perpendicular to the stem, which gives it the appearance of a bird's head and beak; it makes a durable perch for holding the sunbirds which pollinate the flowers. The flowers, which emerge one at a time from the spathe, consist of three orange sepals and three purplish-blue or white petals. Two of the petals are joined together to form an arrow-like nectary. When the sunbirds sit to drink the nectar, the third petal opens to release the anther and cover their feet in pollen.
Cultivation and uses
Strelitzia reginae is very popular as an ornamental plant. It was first introduced to Britain in 1773, when it was grown at the Royal Botanic Gardens, Kew. Since then, it has been widely introduced around the world, including the Americas and Australia, growing well in any area that is sunny and warm. In the United States, Florida and California are the main areas of cultivation, due to their warm climate. It is a common ornamental plant in Southern California, and has been chosen as the Official Flower of the City of Los Angeles.
In areas with cold winters it is normally grown under glass, in a cool sunny position such as a greenhouse or conservatory, as it tolerates only light frosts and does not grow well in temperatures below 10 °C (50 °F). However it may be placed outside during the summer months. It has gained the Royal Horticultural Society's Award of Garden Merit.
It is a low-maintenance plant that is easy to grow in the garden; it is fairly tolerant of soil conditions and needs little water once established. If cared for well, they will flower several times in a year. They will thrive in rich loamy soil, especially when they get plenty of water throughout the year. They do well in full sun to semi-shade and respond well to regular feeding with a controlled release fertiliser and compost.[citation needed] They are sensitive to cold and need to be sheltered from frost, as it can damage the flowers and leaves.
S. reginae is propagated by seed or division. Seedlings are slow-growing and will not bloom for three to five years, though it can exceptionally flower at two years. It flowers only when properly established and division of the plant may affect flowering patterns. The flowers are, however, quite long-lasting once they appear. Peak flowering is in the winter and early spring. There is a yellow-flowered cultivar of this plant known as ‘Mandela's Gold. From https://en.wikipedia.org/wiki/Strelitzia_reginae
