케이프끈끈이주걱-[정명] Drosera capensis L.식물/들꽃-끈끈이주걱과(Droseraceae) 2025. 1. 31. 15:00
Drosera capensis, commonly known as the Cape sundew, is a small rosette-forming carnivorous species of perennial sundew native to the Cape in South Africa. Because of its size, easy-to-grow nature, and the copious amounts of seed it produces, it has become one of the most common sundews in cultivation, and thus, one of the most frequently introduced and naturalised invasive Drosera species.
Description
D. capensis produces strap-like leaves, up to 3.5 centimetres (1.4 in) long (not including the petiole) and 0.5 centimetres (0.2 in) wide, which, as in all sundews, are covered in brightly coloured tentacles which secrete a sticky mucilage that traps arthropods. It is a perennial, herbaceous plant that forms a rosette with a diameter of 18 to 25 cm (7.1 to 9.8 in) and is characterized by numerous, reddish glandular erosions on 7 cm (2.8 in) long and 5 mm (0.20 in) wide, elongated leaves.
The plant flowers in summer (December and January in its native habitat in South Africa) with up to fifty pale-violet, over 2-centimetre (0.79 in) large flowers, borne on up to 35 cm (14 in) high racemose inflorescences. The flowers can self-pollinate upon closing and produce copious quantities of very small, spindle-shaped seeds, which are released from the capsules that form when the flowers have died. The plant thrives in full sun locations on nutrient-poor, waterlogged and lime-free soils.
