Question: What are Echinacea and Bamboo?

full_context: Document 1: Semiarundinaria fastuosa: Semiarundinaria fastuosa, common names Narihira bamboo, Narihira cane, and Narihiradake, is a species of flowering plant in the grass family Poaceae, native to Japan. Growing to 7 m tall by 2 m broad, it is a vigorous, evergreen bamboo with dark green cylindrical canes and dense tufts of lanceolate, glossy green leaves, up to 20 cm long.
Document 2: Bamboo: The bamboos are evergreen perennial flowering plants in the subfamily Bambusoideae of the grass family Poaceae. In bamboo, as in other grasses, the internodal regions of the stem are usually hollow and the vascular bundles in the cross section are scattered throughout the stem instead of in a cylindrical arrangement. The dicotyledonous woody xylem is also absent. The absence of secondary growth wood causes the stems of monocots, including the palms and large bamboos, to be columnar rather than tapering.
Document 3: Echinacea: Echinacea is a genus, or group of herbaceous flowering plants in the daisy family. The "Echinacea" genus has nine species, which are commonly called purple coneflowers. They are found only in eastern and central North America, where they are found growing in moist to dry prairies and open wooded areas. They have large, showy heads of composite flowers, blooming from early to late summer. The generic name is derived from the Greek word ἐχῖνος ("ekhinos"), meaning "hedgehog," due to the spiny central disk. These flowering plants and their parts have different uses. Some species are cultivated in gardens for their showy flowers. "Echinacea purpurea" is used in folk medicine. Two of the species, "E. tennesseensis" and "E. laevigata", are listed in the United States as endangered species.
Document 4: Fargesia murielae: Fargesia murielae, the umbrella bamboo, is a species of flowering plant in the family Poaceae. It is a large, clump-forming evergreen bamboo, closely resembling "Fargesia nitida" in the same genus, but with yellow canes.
Document 5: List of bamboo species: Bamboo    is a group of woody perennial grasses in the true grass family Poaceae, which is a large family with over 10,000 species. In the tribe "Bambuseae" also known as bamboo, there are 91 genera and over 1,000 species. The size of bamboo varies from small annuals to giant timber bamboo. Bamboo evolved only 30 to 40 million years ago, after the demise of the dinosaurs. Bamboo is the fastest-growing woody plant in the world. It can grow up to 91–122 centimetres/day (3.8-5.0 centimetres/hr).
Document 6: Chimonobambusa: Chimonobambusa is a genus of East Asian bamboo in the grass family. They are native to China, Japan, Vietnam, Myanmar, and the Himalayas.
Document 7: Phyllostachys heteroclada: Phyllostachys heteroclada, the fishscale bamboo, also known as "water bamboo", is a running bamboo. The water bamboo name comes from the air canals in the rhizomes and roots that allow this bamboo to grow in more saturated conditions as compared to similar species. This species can also have abrupt kinks at the base of the culms. Maximum height can reach 35+' with a diameter of 2". Cold hardy to around -5F. Grows well in USDA zone 6b-10.
Document 8: Echinopsis: Echinopsis is a large genus of cacti native to South America, sometimes known as hedgehog cactus, sea-urchin cactus or Easter lily cactus. One small species, "E. chamaecereus", is known as the peanut cactus. The 128 species range from large and treelike types to small globose cacti. The name derives from "echinos" hedgehog or sea urchin, and "opsis" appearance, a reference to these plants' dense coverings of spines.
Document 9: Echinacea angustifolia: Echinacea angustifolia (narrow-leaved purple coneflower or blacksamson echinacea) is a North American plant species in sunflower family. It is widespread across much of the Great Plains of central Canada and the central United States, with additional populations in nearby regions.
Document 10: Climbing palm: Climbing palms are genera in the family Arecaceae that grow as lianas. "Initially erect, the slender stems seek out trees for support and climb up into the forest canopy by means of recurved hooks and spines growing on the stem, leaves and inflorescences. In all climbing palms the leaves are pinnate and grow along the stem instead of forming a dense crown. The stems of climbing palms, more often referred to as canes, are solid in contrast to bamboo poles which are almost always hollow." "The majority of climbing palms are also clumping palms <nowiki>[and sympodial]</nowiki>, sending out new shoots from <nowiki>[below ground as suckers]</nowiki>." "About 600 species of palms in <nowiki>[16]</nowiki> genera have a climbing growth habit. Most noteworthy is the genus "Calamus"--the largest genus in the palm family with approximately 350 described species--source of nearly all commercial rattan."
Document 11: Centaurea: Centaurea ( ) is a genus of between 350 and 600 species of herbaceous thistle-like flowering plants in the family Asteraceae. Members of the genus are found only north of the equator, mostly in the Eastern Hemisphere; the Middle East and surrounding regions are particularly species-rich. Common names for this genus are centaury, centory, starthistles, knapweeds, centaureas and the more ambiguous "bluets"; a vernacular name used for these plants in parts of England is "loggerheads" (common knapweed). The "Plectocephalus" group – possibly a distinct genus – is known as basketflowers. "Cornflowers" is used for a few species, but that term more often specifically means "C. cyanus" (sometimes also called "basket flower"). The common name "centaury" is sometimes used, although this also refers to the unrelated plant genus "Centaurium".
Document 12: Phyllostachys aureosulcata: Phyllostachys aureosulcata, the yellow groove bamboo, is a species of bamboo native to the Zhejiang Province of China . It is a running bamboo with a distinctive yellow stripe in the culm groove (or sulcus) that is often grown as an ornamental.
Document 13: Euphorbia: Euphorbia is a very large and diverse genus of flowering plants, commonly called spurge, in the spurge family (Euphorbiaceae). "Euphorbia" is sometimes used in ordinary English to collectively refer to all members of Euphorbiaceae (in deference to the type genus), not just to members of the genus. Some euphorbias are commercially widely available, such as poinsettias at Christmas. Some are commonly cultivated as ornamentals, or collected and highly valued for the aesthetic appearance of their unique floral structures, such as the crown of thorns plant. Euphorbias from the deserts of Southern Africa and Madagascar have evolved physical characteristics and forms similar to cacti of North and South America, so they (along with various other kinds of plants) are often incorrectly referred to as "cacti". Some are used as ornamentals in landscaping, because of beautiful or striking overall forms, and drought and heat tolerance.
Document 14: Echinacea sanguinea: Echinacea sanguinea (sanguine purple coneflower) is a herbaceous perennial native to open sandy fields and open pine woods and prairies in eastern Texas, southeastern Oklahoma, Louisiana, and southwestern Arkansas. It is the southernmost "Echinacea" species. The specific epithet "sanguinea", which is Latin for "blood", refers to the color of the petals.
Document 15: Eupatorieae: Eupatorieae is a tribe of over 2000 species of plants in the aster family. Most of the species are native to tropical, subtropical, and warm temperate areas of the Americas, but some are found elsewhere. Well-known members are "Stevia rebaudiana" (used as a sugar substitute), a number of medicinal plants ("Eupatorium"), and a variety of late summer to autumn blooming garden flowers, including "Ageratum" (flossflower) and "Conoclinium" (mistflower).
