Sempervivum is a genus of about 40 species of flowering plants in the family Crassulaceae, commonly known as houseleeks. Other common names include liveforever and hen and chicks, a name shared with plants of other genera as well. They are succulent perennials forming mats composed of tufted leaves in rosettes. In favourable conditions they spread rapidly via offsets, and several species are valued in cultivation as groundcover for dry, sunny locations.
Aeonium, the tree houseleeks, is a genus of about 35 species of succulent, subtropical plants of the family Crassulaceae. Many species are popular in horticulture. The genus name comes from the ancient Greek "αιώνιος"/"aionios" (ageless). While most of them are native to the Canary Islands, some are found in Madeira, Cape Verde, Morocco, in East Africa and Yemen.

Erysimum cheiri, syn. Cheiranthus cheiri, the wallflower, is a species of flowering plant in the family Brassicaceae (Cruciferae), native to Greece, but widespread as an introduced species elsewhere. It is also treated as a hybrid under the name Erysimum × cheiri. It is widely cultivated as a garden plant.
Aeonium undulatum is a succulent, evergreen flowering plant in the family Crassulaceae. It is a subshrub, one of the larger species of Aeonium with an 8–12 inches (200–300 mm) rosette of bright, glossy green leaves often over a metre from the ground on a single, unbranched stem. Other rosettes do not branch off this stem (normally) but grow from the bottom, unlike most aeoniums. The plant is monocarpic so the flowering stem will die when after producing its yellow inflorescence, which is normally after about 5 years.
Aeonium tabuliforme, the flat-topped aeonium or saucer plant, is a species of succulent plant in the family Crassulaceae, native and endemic to Tenerife in the Canary Islands. It is low-growing, typically reaching about 5 cm high but up to 45 cm in diameter. It grows on moist, north-facing cliffs and ledges at low altitude. A mass of fleshy, hairy, bright green leaves in flat rosettes is produced on short unbranched stems, often on vertical surfaces. This species is short-lived and dies after flowering. Plants often take 3-4 years to flower, at which point they produce a tall raceme of yellow flowers.

Sedum laxum is a species of flowering plant in the family Crassulaceae known by the common name roseflower stonecrop. It is native to southwestern Oregon and northwestern California, where it can be found in rocky mountainous habitat. It is a succulent plant forming basal rosettes of oval or oblong leaves up to 3 centimeters long. The inflorescence is made up of one or more erect arrays of many flowers. The flowers have reddish or yellowish petals up to 1.3 centimeters long each.
Sedum spathulifolium is a species of flowering plant in the family Crassulaceae known by the common names broadleaf stonecrop, yellow stonecrop, and spoon-leaved stonecrop. An evergreen perennial, it is native to western North America from British Columbia to southern California, where it can be found often in shade in many types of rocky habitat in coastal and inland hills and mountains.
Sempervivium calcareum, the houseleek, is a species of flowering plant in the stonecrop family Crassulaceae, native to the southern Alps in Europe.

This plant reproduces with asexual budding and monocarpic sexual reproduction.
Crassula ovata, commonly known as jade plant, lucky plant, money plant or money tree, is a succulent plant with small pink or white flowers that is native to the KwaZulu-Natal and Eastern Cape provinces of South Africa, and Mozambique; it is common as a houseplant worldwide. Much of its popularity stems from the low levels of care needed; the jade plant requires little water and can survive in most indoor conditions. It is sometimes referred to as the money tree; however, Pachira aquatica also has this nickname.
Gasteria bicolor is a species of succulent flowering plant in the family Asphodelaceae, native to the Eastern Cape, South Africa.
Sempervivum ciliosum, the Teneriffe houseleek, is a species of flowering plant in the stonecrop family Crassulaceae, native to Southeastern Europe. Growing to just 10 cm (3.9 in) high by 50 cm (20 in) wide, it is a spreading evergreen perennial. It forms spheres of pointed, succulent, hairy grey-green leaves. Mature rosettes may produce yellowish flowers on stalks up to 10 cm (3.9 in) in summer. Despite a superficial resemblance, houseleeks are not closely related to cacti.
Aeonium dodrantale is a species of tree houseleek in the family Crassulaceae.
