  • Dahlia is a genus of bushy, tuberous, perennial plants native to Mexico, Central America, and Colombia. There are at least 36 species of dahlia. Dahlia hybrids are commonly grown as garden plants. The Aztecs gathered and cultivated the dahlia for food, ceremonies, as well as decorative purposes, and the long woody stem of one variety was used for small pipes.

  • Senecio is a genus of the daisy family that includes ragworts and groundsels. The flower heads are normally rayed, completely yellow, and the heads are borne in branched clusters. Senecio is one of the largest genera of flowering plants, and despite the separation of many species into other genera it still contains over 1000 species of varied form, including leaf, stem and tuber succulents, annuals, perennials, aquatics, climbers, shrubs and small trees.

  • Calendula, pot marigold, is a genus of about 12-20 species of annual or perennial herbaceous plants in the daisy family Asteraceae, native to the area from Macaronesia east through the Mediterranean region to Iran. Calendula should not be confused with other plants that are also known as marigolds, such as plants of the genus Tagetes, corn marigolds or marsh marigolds.

  • Aster is a genus of flowering plants in the family Asteraceae. The genus once contained nearly 600 species in Eurasia and North America, but after morphologic and molecular research on the genus during the 1990s, it was decided that the North American species are better treated in a series of other related genera. After this split there are roughly 180 species within the genus, all but one being confined to Eurasia.

  • Gaillardia, the Blanket flowers, is a genus of drought-tolerant annual and perennial plants from the sunflower family, native to North America and South America. It was named after M. Gaillard de Charentonneau, an 18th-century French magistrate who was a patron of botany. The common name refers to the inflorescence's resemblance to brightly patterned blankets made by native Americans.

  • A salsify, or goatsbeard, is a flowering plant in the genus Tragopogon. Tragopogon is in the family Asteraceae and has over 140 species, including the vegetable known as salsify, as well as a number of common wild flowers, some of which are usually regarded as weeds. Salsifies are forbs growing as biennial or perennial plants. They have a strong taproot and milky sap. They generally have few branches, and those there are tend to be upright. Their leaves are somewhat grass-like.

  • Centaurea is a genus of at least some 350, if not 500 to 600 species of herbaceous thistle-like flowering plants in the family Asteraceae. Although the genus' distribution is Holarctic, most are native to the Palaearctic, where the Middle East and surrounding regions are particular species-rich. Common names for this genus are starthistles, knapweeds, centaureas and the more ambiguous "bluets"; a vernacular name used for these plants in parts of England is "loggerheads".

  • Burdock is any of a group of biennial thistles in the genus Arctium, family Asteraceae. Native to the Old World, several species have been widely introduced worldwide. Plants of the genus Arctium have dark green leaves that can grow up to 28" (71 cm) long. They are generally large, coarse and ovate, with the lower ones being heart-shaped. They are woolly underneath. The leafstalks are generally hollow. Arctium species generally flower from July through to October.

  • Common chicory (Cichorium intybus) is a bushy perennial herb with blue, lavender, or occasionally white flowers. It grows as a wild plant on roadsides in its native Europe, and in North America and Australia, where it has become naturalized. Common chicory is also known as blue sailors, succory, and coffeeweed. It is also called cornflower, although that name is more properly applied to Centaurea cyanus. The cultivated forms are grown for their leaves (var. foliosum), or for the roots (var.

  • Echinacea, is a genus of nine species of herbaceous plants in the family Asteraceae which are commonly called purple coneflowers. All are endemic to 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 genus name is from the Greek echino, meaning "spiny," due to the spiny central disk.

  • Cynara is a genus of about 10 species of thistle-like perennial plants in the family Asteraceae, originally from the Mediterranean region, northwestern Africa, and the Canary Islands. Cynara species are used as food plants by the larvae of some Lepidoptera species including Angle Shades and Double-striped Pug. Among the species in this genus are: Cynara cardunculus is the Cardoon or Artichoke thistle or Wild artichoke, in some places used as a food.

  • Cosmos is a genus of about 20–26 species of annual and perennial plants in the family Asteraceae, native to scrub and meadow areas in Mexico (where the bulk of the species occur), the southern United States, Central America and northern South America south to Paraguay.

  • Ichthyothere is a small genus of about 25 flowering plants, found in parts of South America (the Amazon) and Central America. The name ichthyothere literally translates as fish poison. This plant's active constituent is a chemical called ichthyothereol, which is a polyacetylene compound so toxic to fish that they will jump out of the water if Ichthyothere terminalis leaves are used as bait.

  • Hieracium known by its common name Hawkweed and long ago by its classical name hierakion which comes from the ancient Greek hierax, "a hawk" is a genus of the sunflower family Asteraceae and are closely related to dandelion, chicory, prickly lettuce and sow thistle

  • Tagetes is a genus of 51 species of annual and perennial herbaceous plants in the daisy family. They are native to the area stretching from the southwestern United States into Mexico and south throughout South America. The different species vary in size from 0.05-2.2 m tall. They have pinnate green leaves, and white, golden, orange, yellow, to an almost red floral heads typically (0.1-) to 4-6 cm diameter, generally with both ray florets and disc florets.

  • Zinnia is a genus of 20 species of annual and perennial plants of family Asteraceae, originally from scrub and dry grassland in an area stretching from the American Southwest to South America, but primarily Mexico, and notable for their solitary long-stemmed flowers that come in a variety of bright colors. Zinnia leaves are opposite and usually stalkless (sessile), with a shape ranging from linear to ovate, and pale to middle green in color.

  • Bidens is a genus in the family Asteraceae. It contains about 200 species. The common names beggarticks, bur-marigolds, stickseeds, tickseeds and tickseed sunflowers refer to the achene burrs on the seeds of this genus, most of which are barbed. The generic name refers to the same fact; it means "two-tooth", from Latin bis "two" + dens "tooth". The plants are zoochorous; their seeds will stick to clothing, fur or feathers, and be carried to new habitat.

  • Ragweeds (Ambrosia), also called bitterweeds or bloodweeds, are a genus of flowering plants from the sunflower family. The scientific name of this genus is sometimes claimed to be derived from the Ancient Greek term for the perfumed nourishment of the gods, ambrosia (ἀμβροσία), which would be ironic, since the genus is best known for one fact: its pollen produces severe and widespread allergies.

  • Bahia is a small genus of about 12 species of perennial flowering plants in the family Asteraceae. The common name is also Bahia. The genus has a disjunct distribution in the southwestern United States and Chile, and is found in dry areas.
