Cape Sundew Drosera Capensis
Cape Sundew is a member of the Sunflower family, the drosera being native to southern Europe and the Western Pacific. Like all members of this family, it is an annual species that blooms for a few months in spring and leaves for another few months in autumn. The flowers are showy but quite small, with the petals being wider than the lance-shaped white collar around the flower. Though not related to any carnivorous plant family, the leaves of Cape Sundew contain many elements that are poisonous to humans: the resin corticosteroid known as carotene is present, together with vitamin A and Vitamin C, as well as methyl salicylate, and these represent the active ingredients of the poisonous venom of the tundra snail, Thysanura.
Like other members of its genus, the Cape Sundew has very large leaves: the cap margin (the outer surface) can be two to three times larger than the main leaf body, and the leaflets grow in a very irregular pattern. The dark green leaves are narrow with a pointed tip and grow in a distinct crescent shape around the base of the flower. As with many members of its genus, the flower is covered with small white fuzzy caps which are covered in prickly hairs. These hairs act as protective spines to protect the tender roots against external predators.
The name Cape Sundew comes from the coastal sand dunes where the plant is native, and which also explains why this plant only grows on this flat sand dune soil. In fact, the most popular herb in this area is called Sander’s Bush; the dried leaves are used as seasoning or in salads, and the roots of the plant are eaten by birds. Other carnivorous plants growing on this same sand dune include wood ash, which is edible, and ground-up pine needles, although both of these plants rarely grow to maturity. All carnivorous plants grow better in acidic soils with low levels of nitrogen and phosphorus; they also need a lot of light to thrive.
One of the reasons why the Cape Sundew looks different to other carnivorous plants is that it doesn’t have true flowers. Flowers are the basic reproductive organ of carnivores, and all carnivorous plants have them. The Cape Sundew has thylakoid flowers which are actually a type of flower called petals, and which lack the ray flowers typical of true flowers. The thylakoid flowers are also very short, being no more than one or two inches long.
Like most members of its genus, the Cape Sundew has a solitary flowering plant, which is called a cactus. It has alternate leaves, which grow in pairs just below the main leaf body. The underside of these leaves may be colored like that of the plant’s petals. These plants usually flower in the spring.
While it is the only member of its genus that does not bear flowers, the Cape Sundew has several species of catkins. These plants grow on the outside of the leaves and look similar to a cactus. They are also called catkins because they have a “neck” which hangs down toward the base of the plant. However, unlike the cactus, which has a bulbous top, the catkins have spines projecting out from their tops.
Like many carnivorous plants, the Cape Sundew has a hardy stem. The stem is strong enough to hold the weight of the large leaves, and has thick, overlapping leaves that form a protective canopy over the plant. In fact, the flowers hold the primary attraction for insects that come to the plant. Many times when a butterfly stumbles onto the flowers, it is bound to take one of the petals with it.
The Cape Sundew grows on mostly alkaline soil, although it does grow in some loamy soils that are slightly acidic. It prefers fertile, well drained soil, but will do equally well in moderately acidic ones as well. In addition, the flowers can be pollinated by bees and butterflies, and the fragrance of their fragrances is often quite powerful. The plant is a fast growing plant, rising to about fifteen feet high. It is quite popular as a landscape plant due to its graceful size, easy maintenance and attractive blooms.
