Report sightings of Target Plant Species. Cape Town's Early Detection and Rapid Response (EDRR) Programme has identified 25 Target Plant Species. Although there are 383 plants listed in South Africa's invasive species legislation, Cape Town's Invasive Species Unit requests that you ONLY report the location of 'target species' as listed below.
A succulent and perennial plant from tropical South America introduced as ornamental and barrier plant. It is a spiny vine in the Cactaceae family with strongly scented flowers in white, cream or pinkish, 2.5–5 cm diameter. The leaves are 4–11 cm long and 1.5–4 cm broad, simple, entire, and deciduous in the dry season. Younger stems have hooked thorns and older stems have clusters of woody spines. Leaves and fruits are edible and the seeds are spread by birds and other animals feeding on the fruit.
Bryophyllum delagoense (commonly known as Chandelier plant or Mother-of-Millions) is an erect, hairless succulent perennial originating from Madagascar. Growing from 30cm to 1.2m in height, its stems are pinkish-brown to greyish in colour. The leaves are shaped like a pencil, pale green to pale brown in colour, with dark green patches and a shallow groove on the upper surface. There are up to seven projections at the tip of each leaf which when broken off can develop into new plants. Competes with indigenous species and is very poisonous to humans and animals. Its flowers are orange-red in colour and group in a cluster at the top of a single stem. It flowers in June and July.
Verbesina encelioides is an erect annual reaching 30 cm and up to 160 cm and grows from a taproot system. Leaves are toothed or lobed and have two growth patterns: lower leaves are opposite and triangular, while the upper leaves are alternate and lance shaped. Fine white hairs are present on the underside of leaves and on the stem. Flower heads are bright yellow and found on elongated stalks and resemble small sunflowers, and are 2.5 to 5 cm in diameter. This species originates from North and Central America.
An erect, perennial herbaceous plant with hairy stem and leaves. Tall flower spikes above the plant with bright pink fluffy flower heads surrounded by purple bracts from December to March. The slightly serrated leaves closest to the ground are dense and large (80mm long by 20mm wide), decreasing in size and density higher up the plant. The flowers give way to a cluster of greyish-brown wind-dispersed seeds not dissimilar to a dandelion arrangement (only more robust and dense). This plant is native to Central and South America.
This is an unarmed, multi-stemmed shrub, native to Europe and growing to 1,5m-2,5m in height, with upright long and slender cylindrical green branches. The leaves are simple, undivided, silky beneath and blue-green in colour. Fragrant yellow flowers 25mm long and in racemes 300-400mm long are produced from August to November. Seeds consist of flattened brown pods up to 75mm long, initially covered with silky white hairs.
