Distribution of Aloe arborescens |
Aloe arborescens, the krantz aloe or candelabra aloe, is a species of flowering succulent perennial plant that belongs to the genus Aloe , which it shares with the well known and studied Aloe vera . The specific epithet arborescens means "tree-like". [2] Aloe arborescens is valued by gardeners for its succulent green leaves, large vibrantly-colored flowers, winter blooming, and attraction for birds, bees, and butterflies.
Aloe arborescens is a large, multi-headed, sprawling succulent, and its specific name indicates that it sometimes reaches tree size. [3] A typical height for this species is 2–3 metres (6.6–9.8 ft) high. Its leaves are succulent and are green with a slight blue tint. Its leaves have small spikes along its edges and are arranged in rosettes situated at the end of branches. [4] Flowers are arranged in a type of inflorescence called a raceme. The racemes are not branched but two to several can sprout from each rosette. Flowers are cylindrical in shape and are a vibrant red-orange color. [3]
Taxonomically, it forms part of the Arborescentes series of very closely related Aloe species, together with Aloe pluridens and Aloe mutabilis . [5]
Aloe arborescens is endemic to the south eastern part of Southern Africa. Specifically, this range includes the countries of South Africa, Malawi, Mozambique, and Zimbabwe. [4] It has the third largest distribution amongst the aloe genus. [3] Although Aloe arborescens has adapted to many different habitats, its natural habitat usually consists of mountainous areas, including rocky outcrops and exposed ridges. Its common name krantz aloe refers to the Afrikaans word "krans" (spelling possibly influenced by German "Kranz"), [6] which means a rocky cliff. Its habitat can vary, and it is one of only a few species of aloe that is found growing from sea level up to the tops of mountains. [3]
It is also widely distributed (to the point of becoming naturalized) in the western Mediterranean, Australia, California, Japan, South Korea and the Marshall Islands. It is an invasive species in Portugal. [1]
Aloe arborescens is valued by gardeners for its succulent green leaves, large vibrantly-colored flowers, and winter blooming. The sweet nectar attracts birds, butterflies, and bees. With a minimum temperature of 10 °C (50 °F), [7] in temperate regions it is grown under glass. The cultivar A. arborescens 'Variegata' has gained the Royal Horticultural Society's Award of Garden Merit. [8] In Southern Africa, Aloe arborescens is traditionally planted around kraals (domestic stock enclosures) as a living fence or security hedge. It often happens that the position of old kraals can still be seen many years after they have been abandoned, because the aloes persist. It is easily propagated by cuttings. [3]
Aloe is a genus containing over 650 species of flowering succulent plants. The most widely known species is Aloe vera, or "true aloe". It is called this because it is cultivated as the standard source for assorted pharmaceutical purposes. Other species, such as Aloe ferox, are also cultivated or harvested from the wild for similar applications.
Gonialoe variegata, also known as tiger aloe and partridge-breasted aloe, is a species of flowering plant in the family Asphodelaceae. It is an evergreen succulent perennial indigenous to South Africa and Namibia. It is common in cultivation.
Aloe polyphylla, the spiral aloe, kroonaalwyn, lekhala kharetsa, or many-leaved aloe, is a species of flowering plant in the genus Aloe that is endemic to the Kingdom of Lesotho in the Drakensberg mountains. An evergreen succulent perennial, it is well known for its strikingly symmetrical, five-pointed spiral growth habit.
Gonialoe dinteri, the Namibian partridge aloe, is a species of flowering plant in the Asphodelaceae family. It is native to arid areas of Angola and Namibia.
Gonialoe sladeniana is a species of plant in the genus Gonialoe. It is endemic to arid areas of central Namibia.

Kumara plicatilis, formerly Aloe plicatilis, the fan-aloe, is a succulent plant endemic to a few mountains in the Fynbos ecoregion, of the Western Cape in South Africa. The plant has an unusual and striking fan-like arrangement of its leaves. It may grow as a large multistemmed shrub or as a small tree. It is one of the two species in the genus Kumara.
Aloiampelos commixta is a flowering plant in the Asphodelaceae family. It is commonly called Table Mountain aloe, and is a rare succulent plant that is endemic to the Cape Peninsula, South Africa. It naturally occurs only on the Table Mountain range, within the city of Cape Town.
Aloiampelos striatula, formerly Aloe striatula, the hardy aloe or striped-stemmed aloe, is a sturdy succulent plant that naturally occurs on the summits of mountains along the south of the Karoo region of South Africa. Tough and hardy, with bright yellow flowers, it is also cultivated as a garden ornamental.
Aloe perfoliata, the rubble aloe or mitre aloe, is a hardy creeping aloe, found in rocky, mountainous areas throughout the Western Cape, South Africa.
Aloe petricola belongs to the genus Aloe in the family Asphodelaceae, and is commonly known as a stone aloe. This particular aloe is a flowering species with unique and distinct inflorescences, which make the plant easy to identify and distinguish from other Aloe plants. Aloe petricola is very popular for gardening because of its beautiful and radiant colors. Like many Aloe species, Aloe petricola is used for medical purposes, as it aids in healing wounds and minor burns.
Aloe brevifolia, the short-leaved aloe, is a species of flowering plant in the family Asphodelaceae. It is a tiny, compact, blue-green evergreen succulent perennial, that is native to the Western Cape, South Africa. Listed as Endangered on SANBI's Red List, it is threatened in its natural habitat, but is also widely popular as an ornamental plant in rockeries and desert gardens worldwide.
Agave parviflora is a species of succulent perennial flowering plant in the asparagus family, known by the common names Santa Cruz striped agave, smallflower century plant, and small-flower agave. It is native to Arizona in the United States and Sonora in Mexico.
Aloe bakeri is a species of flowering plant in the family Asphodelaceae, native to Madagascar, where it grows on rocky hills at low elevations. Growing to 10–20 cm (4–8 in) tall by 40 cm (16 in) wide, it is an evergreen perennial forming multiple rosettes of spidery succulent green or reddish-green toothed leaves, heavily mottled with white. The leaves are typically 10 cm long and bear straight or slightly curved white teeth that are 1 mm long and about 1-2 mm apart. In summer it produces red or orange, green-tipped tubular flowers. These flowers are attractive to birds, bees, and wasps, and are typically 2 cm long, borne on racemes 30 cm tall.
Aloe pluridens is an arborescent aloe indigenous to southern Africa.
Aloe rupestris is an arborescent aloe indigenous to summer-rainfall areas of southern Africa.
Aloe macra is a species of Aloe endemic to the island of Réunion, in the Indian Ocean.
Aloeae is a tribe of succulent plants in the subfamily Asphodeloideae of the family Asphodelaceae, consisting of the aloes and their close relatives. The taxon may also be treated as the subfamily Alooideae by those botanists who retain the narrower circumscription of Asphodelaceae adopted prior to the APG III system. Typically, plants have rosettes of more or less succulent leaves, with or without a distinct stem. Their flowers are arranged in racemes and tend to be either small and pale, pollinated by insects, or larger and more brightly coloured, pollinated by birds. As of 2017, 11 genera are recognized, most created since 2010 by splitting off another five genera from Aloe and another two from Haworthia. Only two genera, Aloe and Aloidendron, are native outside southern Africa, extending northwards to the Arabian Peninsula. Seven genera are restricted to South Africa, some with small ranges. Members of the Aloeae are cultivated by succulent plant enthusiasts; Aloe species especially are used in temperate climates as ornamental garden plants. Some species are used in traditional medicine. Aloe vera and Aloe ferox are cultivated for their extracts, whose uses include moisturizers and emollients in cosmetics.
