Hedera algeriensis, the Algerian ivy, is a species of evergreen ivy native to the North African coast, including coastal mountains in Algeria. [1]
It is a vigorous, large evergreen climber, self-clinging by aerial roots. The stems are reddish, partly decorated with stellate hairs or scales, reddish-starred with about 15 rays. The leaves are alternate and simple. As in other Hedera species, the fertile branches have stiff stems with leaves having usually fewer lobes compared to the sterile (juvenile) stems. The main part of the leaf (the lamina) is oval-rhombic, 12–20 cm by 5–12 cm on flowering branches and coarsely toothed or slightly lobed (3-5 lobes) on the sterile stems. The inflorescence is a cluster of 13-15 pubescent flowers. Small flowers in umbels develop only on the fertile stems or branches. The plant contains the glycoside hederagenin, mostly in the leaves and berries, which could cause a mild toxicosis. If these parts are ingested it may cause severe discomfort, and handling plants may cause skin irritation or an allergic reaction. The plant is rejected by herbivorous animals. Variegated cultivars of Hedera algeriensis are widely used in gardening. It naturalizes in mild climates and lowlands.
The cultivar 'Ravensholst' [2] has gained the Royal Horticultural Society's Award of Garden Merit.
It may be a noxious weed or be invasive. It requires consistently moist soil, but is more resistant to environmental dryness than most related species and can stand drought better than other ivies. It tolerates low temperatures better than island species of similar latitudes, such as Hedera canariensis , Hedera maderensis , Hedera azorica , or Hedera cypria . It is native to the North African coast and coastal mountains where the climate is cooler and condensation provides a more humid habitat. It is frost sensitive at about the -2 °C winter isotherm but can become naturalised in mild climates. Hedera algeriensis arose from a common ancestor in the cloud forest habitat in the Mediterranean area. The northern African Hedera and northeast Atlantic species of the genus Hedera are closely related species. Until recently it was thought there was a single species, [3] Hedera helix, but recent studies have shown that there are several species that differ mainly by microscopic details of the hairiness of the buds. Hedera maroccana , Hedera iberica , and Hedera canariensis are closely related.
Hedera algeriensis has been cultivated in Britain since 1838.
In Coastal California Algerian ivy is used as a ground cover on highway embankments to help control erosion. [4] Without irrigation it can be difficult to establish and maintain, [5] and can hide underlying dead, dry material, which can be a fire hazard. [6] The ivy groundcover provides cover, food and herbage for roof rats and snails. [7]
Hedera, commonly called ivy, is a genus of 12–15 species of evergreen climbing or ground-creeping woody plants in the family Araliaceae, native to Western Europe, Central Europe, Southern Europe, Macaronesia, northwestern Africa and across central-southern Asia east to Japan and Taiwan.
Ilex opaca, the American holly, is a species of holly, native to the eastern and south-central United States, from coastal Massachusetts south to central Florida, and west to southeastern Missouri and eastern Texas.
Salvia spathacea, the California hummingbird sage, hummingbird sage, or pitcher sage, is a species of flowering plant in the family Lamiaceae, native to southern and central California growing from sea level to 610 m (2,001 ft). This fruity scented sage blooms in March to May with typically dark rose-lilac colored flowers. It is cultivated in gardens for its attractive flowering spikes and pleasant scent.
Hedera hibernica, the Atlantic ivy, Boston ivy or Irish ivy, is a species of ivy native to the Atlantic coast of Europe.
Jacobaea maritima, commonly known as silver ragwort, is a perennial plant species in the genus Jacobaea in the family Asteraceae, native to the Mediterranean region. It was formerly placed in the genus Senecio, and is still widely referred to as Senecio cineraria; see the list of synonyms (right) for other names.
Hedera helix, the common ivy, English ivy, European ivy, or just ivy, is a species of flowering plant of the ivy genus in the family Araliaceae, native to most of Europe and western Asia. A rampant, clinging evergreen vine, it is a familiar sight in gardens, waste spaces, and wild areas, where it grows on walls, fences, tree trunks, etc. across its native and introduced habitats. As a result of its hardy nature, and its tendency to grow readily without human assistance, ivy attained popularity as an ornamental plant, but escaped plants have become naturalised outside its native range and grow unchecked in myriad wild and cultivated areas.
× Fatshedera is hybrid genus of flowering plants, common name tree ivy or aralia ivy. It has only one species, × Fatshedera lizei. The hybrid symbol × in front of the name indicates that this is an inter-generic hybrid, a cross between plants from different genera. The name may be displayed with or without a space after the × symbol.
Fatsia japonica, also fatsi, paperplant, false castor oil plant, or Japanese aralia, is a species of flowering plant in the family Araliaceae, native to southern Japan and southern Korea.
Cortegada is an almost tidal island in a coastal inlet near Pontevedra in Galicia, Spain. It is part of the Atlantic Islands of Galicia National Park.
Malva sylvestris is a species of the mallow genus Malva in the family of Malvaceae and is considered to be the type species for the genus. Known as common mallow to English-speaking Europeans, it acquired the common names of cheeses, high mallow and tall mallow as it migrated from its native home in Western Europe, North Africa and Asia through the English-speaking world.
Dalibarda repens(dewdrop, false violet, star violet, Robin runaway. French Canadian: dalibarde rampante) is a perennial plant in the rose family, native to eastern and central Canada and to the northeastern and north-central United States. It is the only species in the genus Dalibarda, which is closely allied with the genus Rubus. The species is often included in the genus Rubus as Rubus repens (L.) Kuntze. It is fairly easily grown in shady locations in damp to wet, acidic soils, and is frequently used in wildflower and bog gardens as a ground-cover.
Linaria maroccana is a species of flowering plant in the plantain family known by the common names Moroccan toadflax and annual toadflax. It is native to Morocco, but it can be found elsewhere growing wild as an introduced species, such as California. It is a readily available ornamental plant for the flower garden. This is an annual herb growing erect to approach a maximum height of 50 cm (20 in), its stem with linear leaves 2–4 cm (0.8–1.6 in) long. The inflorescence is a raceme of flowers occupying the top of the stem. At the base of each flower is a calyx with five narrow, pointed lobes. The flower is 2–4 cm (0.8–1.6 in) long with five lobes arranged into two lips with a spur at the end. The flower is often purple in color with white near the throat, but flowers of many different colors are bred for the garden. Dwarf cultivars are also available.
Sphenophyllales is an extinct order of articulate land plants and a sister group to the present-day Equisetales (horsetails). They are fossils dating from the Devonian to the Triassic. They were common during the Late Pennsylvanian to Early Permian, with most of the fossils coming from the Carboniferous period.

Hedera canariensis, the Canary Island ivy, Canary ivy or Madeira ivy, is a species of ivy, native to the Canary Islands and possibly the Atlantic coast of northern Africa.
Hedera maderensis, the Madeiran ivy, is a species of ivy which is native to the Atlantic coast in Madeira island. It is a plant of botanical family Araliaceae, species endemic to the island of Madeira with the name: Hedera maderensis. Formerly a subspecies named Hedera maderensis iberica, one iberian subspecies in west Iberian peninsula was subsequently classified as a distinct species. It is quite common in Madeira and lives in slopes rock, soil, trunks of trees especially in Laurel forest of Barbusano.
Hedera maroccana, the Moroccan ivy, is a species of ivy which is native to the Atlantic coast in northern Africa. It is an evergreen climbing plant, growing to 20–30 m high where suitable surfaces are available, and also growing as ground cover where there are no vertical surfaces. It climbs by means of aerial rootlets which cling to the substrate. In warm climates, it grows more rapidly and becomes established a good bit faster than the related Hedera hibernica and Hedera helix.
Hedera colchica is a species of ivy which is native to Near and Middle East. It is commonly called Persian ivy or colchis ivy. It is an evergreen climbing plant, growing to 30 m high where suitable surfaces are available, and also growing as ground cover where there are no vertical surfaces. It climbs by means of aerial rootlets which cling to the substrate. In warm climates, it grows more rapidly and becomes established faster than other Hedera species.
Hedera cypria, is a species of Ivy which is endemic to the island of Cyprus. It is an evergreen climbing plant, growing slowly to 20–30 m high where suitable surfaces are available, and also growing as ground cover where there are no vertical surfaces. It climbs by means of aerial rootlets which cling to the substrate. It is more common at higher altitudes in rocky, shadowy riverine forest, over 400–650 m. In its natural habitat it can be distinguished easily from Hedera helix subsp. poetarum, also present, because the latter has yellow fruits, while Hedera cypria is always black-fruited.
Hedera pastuchovii, (Araliaceae) is a species of ivy native to eastern Transcaucasia and listed in The Red Book of the Azerbaijan SSR, 1989.
