Question: Are both the Aglaonema and Alstonia genus of plants evergreen?

full_context: Document 1: Strobilanthes: Strobilanthes is a genus of about 350 species of flowering plants in the family Acanthaceae, mostly native to tropical Asia and Madagascar, but with a few species extending north into temperate regions of Asia. Many species are cultivated for their 2-lipped, hooded flowers in shades of blue, pink, white and purple. Most are frost-tender and require protection in frost-prone areas.
Document 2: Alangium: Alangium is a small genus of flowering plants. The genus is included either in a broad view of the dogwood family Cornaceae, or as the sole member of its own family Alangiaceae. "Alangium" has about 40 species, but some of the species boundaries are not entirely clear. The type species for "Alangium" is "Alangium decapetalum", which is now treated as a subspecies of "Alangium salviifolium". All of the species are shrubs or small trees, except the liana "Alangium kwangsiense". "A. chinense, A. platanifolium", and "A. salviifolium" are known in cultivation.
Document 3: Alstonia: Alstonia is a widespread genus of evergreen trees and shrubs, of the dogbane plant family Apocynaceae. It was named by Robert Brown in 1811, after Charles Alston (1685–1760), Professor of botany at Edinburgh from 1716-1760.
Document 4: Epipremnum: Epipremnum is a genus of flowering plants in the family Araceae, found in tropical forests from China, the Himalayas, and Southeast Asia to Australia the western Pacific. They are evergreen perennial vines climbing with the aid of aerial roots. They may be confused with other Monstereae such as "Rhaphidophora", "Scindapsus" and "Amydrium".
Document 5: Adansonia: Baobab is the common name for each of the nine species of tree in the genus Adansonia. The generic name honours Michel Adanson, the French naturalist and explorer who described "Adansonia digitata".
Document 6: Alpinia: Alpinia is a genus of flowering plants in the ginger family, Zingiberaceae. It is named for Prospero Alpini, a 17th-century Italian botanist who specialized in exotic plants. Species are native to Asia, Australia, and the Pacific Islands, where they occur in tropical and subtropical climates. Several species are cultivated as ornamental plants. Species of the genus are known generally as shell ginger.
Document 7: Colocasia: Colocasia is a genus of flowering plants in the family Araceae, native to southeastern Asia and the Indian subcontinent. Some species are widely cultivated and naturalized in other tropical and subtropical regions. Common names include tarul, karkala ko ganu, elephant-ear, taro, cocoyam, dasheen, chembu, champadhumpa, shavige gadde, and eddoe. Elephant-ear and cocoyam are also used for some other large-leaved genera in the Araceae, notably "Xanthosoma" and "Caladium". The generic name is derived from the ancient Greek word "kolokasion", which in the Greek botanist Dioscorides (1st century AD) meant the edible roots of both "Colocasia esculenta" and "Nelumbo nucifera". It is thought that the edible roots of "Colocasia esculenta" have been cultivated in Asia for more than ten thousand years. The species "Colocasia esculenta" is an invasive species in wetlands along the American Gulf coast, where it threatens to displace native wetland plants.
Document 8: Spathiphyllum: Spathiphyllum is a genus of about 40 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.
Document 9: Arum: Arum is a genus of flowering plants in the family Araceae, native to Europe, northern Africa, and western and central Asia, with the highest species diversity in the Mediterranean region. Frequently called "arum lilies", they are not closely related to the true lilies "Lilium". Plants in closely related "Zantedeschia" are also called "arum lilies".
Document 10: Colvillea racemosa: Colvillea racemosa is a species of legume in the Fabaceae family. It is also known by the common name Colville's Glory. Its genus is named for Sir Charles Colville, an ex Governor of Mauritius. The tree is particularly known for its bright orange flowers that grow in large cone or cylinder shaped clusters. After flowering, the tree produces long, flat, woody seed pods. The tree has small deep green leaves, superficially similar to "Delonix regia".
Document 11: Pinellia: Pinellia is a genus of plants in the family Araceae native to East Asia (China, Korea, Japan). Its species are commonly called green dragons due to the color and shape of the inflorescence, which possesses a green, hooded spathe from which protrudes a long, tongue-like extension of the spadix. The leaves vary greatly in shape among different species, from simple and cordate to compound with three to many leaflets. "Pinellia" reproduces rapidly from seed and many species also produce bulbils on the leaves. Both characteristics have allowed some species to become weedy in temperate areas outside their native range, notably "Pinellia ternata" in eastern North America.
Document 12: Arenga: Arenga is a genus of palms, native to Southeast Asia, southern China, New Guinea, and northern Australia. They are small to medium-sized palms, growing to 2–20 m tall, with pinnate leaves 2–12 m long. Arenga palms can grow in areas with little sunlight and relatively infertile soil.
Document 13: Amherstia: Amherstia nobilis (Burmese: သော်ကကြီး ] ; the Pride of Burma, in the Fabaceae family) is a tropical tree with large, showy flowers. It is the only member of the genus Amherstia. It is widely cultivated for ornament in the humid tropics, but is very rare in the wild and has only been collected from its native habitat a few times. It is native to Burma (Myanmar), hence the common name. The scientific name commemorates Lady Amherst, (as does Lady Amherst's pheasant) and also her daughter Sarah. Another common name, the Orchid Tree, is otherwise reserved for members of the genus "Bauhinia".
Document 14: Alston (name): Alston is an English language surname of Anglo-Saxon origin with several derivations. It may have evolved from the Middle English given name "Alstan", the prefix, "Al-" itself derived from different Old English words ("noble", "elf", "old", "shrine", "temple"), and the suffix "-stan" ("stone") derived from pre 7th century Old English. The oldest public record of this derivation is found in 1279 in Cambridgeshire. One branch of this name may have been taken from the manor of a Saxon Lord called Alstanus, he had his manor in Stambourne, North East Essex. It is known that he was still in possession of the Manor after the Norman conquest, although as a tenant rather than owner, he held the land annexed against the King. There are a high density of families with the surname Alston and Alliston from around the Sudbury area, not far from Stambourne. In the 1224 feet of fines it is recorded that John son of Adam de Alliston sold land at Stanfeld (Stansfield) Suffolk. Stansfield is a few miles North of Stambourne. Both Stambourne and Stansfield may have taken their name from Æthelstan Half-King, Earl of East Anglia in the 930s.
Document 15: Aglaonema: 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. They are known commonly as Chinese evergreens.
