Adromischus (Lemaire 1852) Small plants in the form of miniature shrubs. Highly reduced stems, very fleshy leaves with a tendency to be rounded and inflated. Highly resistant to water scarcity and direct sunlight. Very sensitive to waterlogging and fungi. They prefer highly mineral soils with little organic matter. Etymology: Adromischus: Derived from the Greek words adros = "thick" and mischos = "stem".Place of Origin: They are endemic to southern Africa
Aeonium (Webb & Berthel. 1840) Succulent plants with rosette shapes on cylindrical stems. Evergreen fleshy leaves. Despite being endemic to the Canary Islands, due to its ease of cultivation, it is widely used as a domestic ornamental plant. Etymology: Derived from the Greek "aionion," meaning ever-living.Place of Origin: Most of them are from the Canary Islands. A few live in Madeira, and in northern and eastern Africa.
Crassula ((L.) Schönl. 1753) It comprises about 200–300 species of shrubby or creeping plants. They feature opposite, fleshy, and generally glabrous leaves. The flowers are small, with five petals, clustered in bouquet-like inflorescences at the stem tips. They are commonly used in gardening. Their main water storage is in the leaves. Etymology: From the Latin "crassus," meaning thick, in reference to the leaves of many species in this genus.Place of Origin: Primarily from southern Africa, although they can be found in many arid regions around the world.
Kalanchoe (Adans 1763) Plants of highly diverse sizes, ranging from small herbaceous specimens to large ones reaching about 6-7 meters. They are perennial plants, although some species exhibit partial leaf loss (not complete) in winter. They feature very distinctive flowering stems in the form of umbels. Blooming occurs between late autumn and early spring. Etymology: From Chinese (kalan chai), which means: “a plant that falls and grows.”Place of Origin: Africa, especially tropical regions.
Sedum (L.1753) Succulent plants distinguished by their fleshy leaves and ability to adapt to extreme environments such as bare rock with complete absence of soil. Highly drought-resistant with remarkable regeneration capacity from even the smallest remnants. Their species can be herbaceous, creeping, or form small shrubs with fragile stems. They produce inflorescences with light-colored star-shaped flowers. They typically form small, carpeting colonies. Etymology: From the Latin “sēdō, sēdere”, to be seated.Place of Origin: Almost the entire Northern Hemisphere: Europe, Asia, North Africa, and Central and North America. Mainly in rocky areas.
Umbilicus (DC. 1801) It is characterized by its fleshy, rounded leaves with a central depression resembling a navel. These leaves are arranged in basal rosettes capable of storing water, allowing the plant to withstand dry periods in rocky habitats. It features slender flowering stems with hanging inflorescences of small flowers. It grows in crevices, walls, and damp cliffs. During summer, it may reduce to a tuberous root hidden within the rock. It possesses a remarkable ability to colonize constructions and vertical surfaces. Etymology: Umbilicate due to the shape of its leaves.Place of Origin: Mediterranean region and Western Asia.
