As soon as another plant blooms and the stigmas are receptive (sticky), the collected pollen can be sprinkled onto the stigmas.Īpproximately four weeks after successful fertilisation, a seedpod of the size of a passion fruit is formed in the horizontal sepal. The pollen can then be stored in the refrigerator. This can be done by gently opening the stamens and carefully run the tip of a straw over the stamens from base to tip. When these different plants bloom, they can be fertilized by hand.įirst the pollen must be collected. However, the Strelitzia is often sold planted as several plants in one pot. The fertilizationĪs indicated earlier, the plant cannot fertilize itself. The stigma is the white tip at the front of the blue arrow, which becomes sticky and therefore receivable as soon as the stamens no longer spread pollen. The stamens become visible when the wings on the back of the blue arrow are pressed together. ![]() The fertile parts are in the horizontal blue’ arrow’. On the horn-shaped horizontal sepal, 4 to 6 flowers are formed with bright orange petals. The flower is also visited by honeysuckers (Nectariniidae) but it seems as if this bird is able to reach the nectar without touching the fertile parts of the flower. It is known that insects, including bees, do visit the flower. Who fertilizes the Strelitzia in nature is not completely clear and is still being researched. This means that several plants are needed to pollinate the flower successfully. But even if the pollen is collected first and then applied to the stigma, this will not lead to fertilisation. ![]() ![]() This means that this monoicous plant is undergoing a certain development to prevent self-pollination.
