Aglaonema is a genus of flowering plants in the arum family, Araceae. They are native to tropical and subtropical regions of Asia and New Guinea. [1] [2] They are known commonly as Chinese evergreens. [3]
These are evergreen perennials with stems growing erect or decumbent and creeping. Stems that grow along the ground may root at the nodes. There is generally a crown of wide leaf blades which in wild species are often variegated with silver and green coloration. The inflorescence bears unisexual flowers in a spadix, with a short zone of female flowers near the base and a wider zone of male flowers nearer the tip. The fruit is a fleshy berry that ripens red. The fruit is a thin layer covering one large seed. [2]
Plants of the genus are native to humid, shady tropical forest habitat. [3]
Aglaonema have been grown as luck-bringing ornamental plants in Asia for centuries. [3] They were introduced to the West in 1885, [3] when they were first brought to the Royal Botanic Gardens, Kew. [4] They have been cultivated, hybridized, and bred into a wide array of cultivars. They live in low-light conditions and are popular houseplants. [3]
This mainly tropical genus is known for its intolerance of cold temperatures. Chilling injury can begin at 15 °C (59 °F). [5] The injury manifests in dark, greasy-looking patches on the foliage. [5]
Cultivars have been selected for their shape and size, and especially for the color and pattern of the leaves. Many have white or cream-colored stems. Some have also been developed to tolerate colder temperatures. [3] The most common cultivar is 'Silver Queen', [3] which has gained the Royal Horticultural Society's Award of Garden Merit. [6] [7]
Most propagation of Aglaonema is done with cuttings and by dividing the basal shoots. Care of the houseplant involves protecting it from cold temperatures and excessive sunlight and removing any inflorescences that develop, which can prolong the life of the plant. It requires moist soil, and while some cultivars require a small amount of fertilizer, plants are easily injured when oversupplemented. [3] Aglaonema are prone to false mites ( Brevipalpus californicus). They may also acquire populations of nematodes, such as root-knot nematodes and Pratylenchus species, which cause root lesions. [8] Pathogens include the fungus Myrothecium roridum and bacteria such as Pseudomonas cichorii , Erwinia chrysanthemi , and Xanthomonas campestris , which can all cause leaf spot. Colletotrichum fungi can cause anthracnose. [9]
The NASA Clean Air Study determined that the species modestum of this plant genus was effective at removing common household air toxins formaldehyde and benzene.
Aglaonema plants are poisonous due to calcium oxalate crystals. If ingested they cause irritation of the mucous membranes, and the juice can cause skin irritation and painful rash. [10]
Species include: [1]
Justicia brandegeeana, the Mexican shrimp plant, shrimp plant or false hop, is an evergreen shrub in the genus Justicia of the acanthus family Acanthaceae, native to Mexico, and also naturalized in Florida.
Epipremnum aureum is a species in the arum family Araceae, native to Mo'orea in the Society Islands of French Polynesia. The species is a popular houseplant in temperate regions but has also become naturalised in tropical and sub-tropical forests worldwide, including northern South Africa, Australia, Southeast Asia, South Asia, the Pacific Islands and the West Indies, where it has caused severe ecological damage in some cases.
Aerides, known commonly as cat's-tail orchids and fox brush orchids, is a genus belonging to the orchid family. It is a group of tropical epiphyte orchids that grow mainly in the warm lowlands of tropical Asia from India to southern China to New Guinea. They are valued in horticulture for their racemes of showy, fragrant, colorful flowers.
Gnetum is a genus of gymnosperms, the sole genus in the family Gnetaceae within the Gnetophyta. They are tropical evergreen trees, shrubs and lianas. Unlike other gymnosperms, they possess vessel elements in the xylem. Some species have been proposed to have been the first plants to be insect-pollinated as their fossils occur in association with extinct pollinating scorpionflies. Molecular phylogenies based on nuclear and plastid sequences from most of the species indicate hybridization among some of the Southeast Asian species. Fossil-calibrated molecular-clocks suggest that the Gnetum lineages now found in Africa, South America and Southeast Asia are the result of ancient long-distance dispersal across seawater.
Antidesma is a genus of tropical plant in the family Phyllanthaceae formally described by Linnaeus in 1753. It is native to tropical Africa, S + E + SE Asia, Australia, and various oceanic islands. The greatest diversity occurs in Southeast Asia.
Spathiphyllum is a genus of about 60 species of monocotyledonous flowering plants in the family Araceae, native to tropical regions of the Americas and southeastern Asia. Certain species of Spathiphyllum are commonly known as spath or peace lilies.
Tradescantia zebrina, formerly known as Zebrina pendula, is a species of creeping plant in the Tradescantia genus. Common names include silver inch plant and wandering Jew. The latter name is controversial, and some now use the alternative wandering dude. The plant is popular in cultivation due to its fast growth and attractive foliage. It is used as a groundcover in warm winter climates, and as a houseplant elsewhere.
Daphniphyllum is the sole genus in the flowering plant family Daphniphyllaceae and was described as a genus in 1826. The genus includes evergreen shrubs and trees mainly native to east and southeast Asia, but also found in the Indian Subcontinent and New Guinea.
Chionanthus, common name: fringetrees, is a genus of about 140 species of flowering plants in the family Oleaceae.
Coleus scutellarioides, commonly known as coleus, is a species of flowering plant in the family Lamiaceae, native to southeast Asia through to Australia. Typically growing to 60–75 cm (24–30 in) tall and wide, it is a bushy, woody-based evergreen perennial, widely grown for the highly decorative variegated leaves found in cultivated varieties. Another common name is painted nettle, reflecting its relationship to deadnettles, which are in the same family. The synonyms Coleus blumei, Plectranthus scutellarioides and Solenostemon scutellarioides are also widely used for this species.
Chamaedorea elegans, the neanthe bella palm or parlour palm, is a species of small palm tree native to the rainforests in Southern Mexico and Guatemala. The parlor palm is one of the most extensively sold houseplant palms in the world. It is one of several species with leaves that are harvested as xate.
Maranta leuconeura, widely known as the prayer plant due to its daily sunlight-dependent movements, is a species of flowering plant in the family Marantaceae native to the Brazilian tropical forests. It is a variable, rhizomatous perennial, growing to 30 cm (12 in) tall and broad, with crowded clumps of evergreen, strikingly-marked oval leaves, each up to 12 cm (5 in) long. The plant spreads itself horizontally, carpeting an entire small area of forest floor, sending roots into the substrate at each leaf node.
Peperomia obtusifolia, also known as the baby rubberplant, American rubber plant, or pepper face, is a species of flowering plant in the genus Peperomia under the family Piperaceae, native to Florida, Mexico and the Caribbean. The specific epithet obtusifolia means "blunt-leaved". The plant has gained the Royal Horticultural Society's Award of Garden Merit.
Pteris cretica, the Cretan brake, ribbon fern, or Cretan brake fern, is a species of evergreen fern in the family Pteridaceae, native to Europe, Asia and Africa.
Scindapsus pictus—commonly called satin pothos, silver pothos, or silver vine—is a species of flowering plant in the aroid or arum family, Araceae, native to Bangladesh, Borneo, India, Java, Peninsular Malaysia, the Philippines, Sulawesi, Sumatra, Taiwan and Thailand. The Latin specific epithet pictus means "painted", referring to the variegation on the leaves.
Syngonium podophyllum is a species of aroid that is a popular houseplant. Common names include: arrowhead plant, arrowhead vine, arrowhead philodendron, goosefoot, nephthytis, African evergreen, and American evergreen. The species is native to a wide region of Latin America from Mexico through Bolivia, and naturalized in the West Indies, Florida, Texas, Hawaii, and other places.
Chisocheton is a genus of trees in the family Meliaceae. The genus name comes from the Greek schizos and chiton meaning "split tunic", referring to the lobed staminal tube of C. patens. Their range is from India and tropical China, throughout Malesia and south to New South Wales and Vanuatu.
