Curio hallianus, syn. Senecio hallianus, is a creeping succulent plant in the daisy family Asteraceae that is native to South Africa. [1] It is also known as chain of blue beans or string of beans.
This perennial is a fleshy, mat-forming, trailing succulent that is very similar in appearance to Curio radicans , but it has blue-grey leaves, whereas radicans has green leaves. [2] The stems contain a gummy resin. The leaves grow on only one side of the stem. [3] Between one and three white flowerheads grow on terminal stems that are up to 10 cm tall. They are fragrant and disc shaped. [3]
This plant is found growing in rock fissures between Prince Albert and the Great Karoo in South Africa. [3]
A cactus is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. The word cactus derives, through Latin, from the Ancient Greek word κάκτος (káktos), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. Although some species live in quite humid environments, most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on Earth. Because of this, cacti show many adaptations to conserve water. For example, almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place. Most species of cacti have lost true leaves, retaining only spines, which are highly modified leaves. As well as defending against herbivores, spines help prevent water loss by reducing air flow close to the cactus and providing some shade. In the absence of true leaves, cacti's enlarged stems carry out photosynthesis. Cacti are native to the Americas, ranging from Patagonia in the south to parts of western Canada in the north—except for Rhipsalis baccifera, which also grows in Africa and Sri Lanka.
Toxicodendron radicans, commonly known as eastern poison ivy or poison ivy, is an allergenic Asian and Eastern North American flowering plant in the genus Toxicodendron. The species is well known for causing urushiol-induced contact dermatitis, an itchy, irritating, and sometimes painful rash, in most people who touch it. The rash is caused by urushiol, a clear liquid compound in the plant's sap. The species is variable in its appearance and habit, and despite its common name, it is not a true ivy (Hedera), but rather a member of the cashew and pistachio family (Anacardiaceae). T. radicans is commonly eaten by many animals and the seeds are consumed by birds, but poison ivy is most often thought of as an unwelcome weed. It is a different species from western poison ivy, T. rydbergii, which has similar effects.
Senecio is a genus of flowering plants in the daisy family (Asteraceae) that includes ragworts and groundsels.
Veronica beccabunga, the European speedwell or brooklime, is a succulent herbaceous perennial plant belonging to the flowering plant family Plantaginaceae. It grows on the margins of brooks and ditches in Europe, North Africa, and north and western Asia. It can be found on other continents as an introduced species. It has smooth spreading succulent branches that are often reddish, blunt oblong finely serrate leaves in opposite pairs close to the stem, and small bright blue or pink flowers with four petals.
Curio rowleyanus, syn. Senecio rowleyanus, is a flowering plant in the daisy family Asteraceae. It is a creeping, perennial, succulent vine native to the drier parts of southwest Africa. In its natural environment its stems trail on the ground, rooting where they touch and form dense mats. It often avoids direct sunlight by growing in the shade of other plants and rocks. It is commonly known as string-of-pearls or string-of-beads.
Curio ficoides, syn. Senecio ficoides, also known as skyscraper Senecio and Mount Everest Senecio, is a species of succulent plant, in the genus Curio (Asteraceae), indigenous to South Africa.

Curio repens, syn. Senecio serpens, is a species of the genus Curio in the Asteraceae family. A succulent endemic to the Western Cape province of South Africa, it is typically found growing from crevices in rocky sandstone slopes. Commonly named blue chalksticks, it is used as an ornamental plant.
In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil conditions. The word succulent comes from the Latin word sucus, meaning "juice" or "sap".
Mesembryanthemum cordifolium formerly known as Aptenia cordifolia is a species of succulent plant in the iceplant family. It is a creeping plant that forms a carpet of flat-growing perennial herbs in groups on the ground from a base. Genus name means middle-embryo flower in reference to the position of the ovary in the flower. The specific epithet is derived from Latin for heart-shaped leaves.
Astroloba rubriflora is a succulent plant found in the mountainous Karoo area around Robertson, South Africa. It is listed as a Vulnerable species on the IUCN global Red List.
Curio radicans, syn. Senecio radicans, is a succulent houseplant that is native to South Africa. A member of the family Asteraceae, the asters, this species is closely related to the common string of pearls and Curio hallianus. It has multiple tendrils of glossy, banana-shaped foliage. It is commonly known as string of bananas or fishhook senecio.
Ipomoea oenotherae is a species of plant of the morning glory genus, Ipomoea, in the family Convolvulaceae. It derives its name from the resemblance it bears to plants in the genus Oenothera. Ipomoea oenotherae is a succulent and a cryptophyte.

Senecio herreanus, which is also known as string of watermelons, string of beads, gooseberry plant and string of raindrops, is a flowering succulent plant in the daisy family Asteraceae that is native to South Africa. It is grown as an ornamental plant and is very similar in appearance to 'string of pearls', where the names may be conflated.
Curio talinoides, syn. Senecio mandraliscae, also known as blue straws, blue chalksticks, dassieharpuis, or narrow-leaf chalk sticks, is a succulent plant of the family Asteraceae that is native to South Africa. The origin of this plant is dubious and it may be a hybrid.
