Krigia is a genus of North American flowering plants in the family Asteraceae. Plants of the genus are known generally as dwarf dandelions [2] or dwarfdandelions. [3]
The species vary in morphology. They are annual or perennial herbs growing from a fibrous root system or a taproot. One species has rhizomes with tubers. The plants produce a single stem or up to 50 or more, usually growing erect, reaching a few centimeters to 75 centimeters tall. Most of the leaves are basal, but some stems have leaves higher up. The blades are often linear to lance-shaped, toothed or lobed, and borne on winged petioles. The flower heads are solitary, growing at the top of the stem or on stalks from the leaf axils. They contain up to 60 yellow or orange flowers. The fruit is a hairless, ribbed cypsela, sometimes with a pappus. [2]
Gaillardia is a genus of flowering plants in the family Asteraceae, native to North and South America. It was named after Maître Gaillard de Charentonneau, an 18th-century French magistrate who was an enthusiastic botanist. The common name may refer to the resemblance of the inflorescence to the brightly patterned blankets made by Native Americans, or to the ability of wild taxa to blanket the ground with colonies. Many cultivars have been bred for ornamental use.
Helianthus is a genus comprising about 70 species of annual and perennial flowering plants in the daisy family Asteraceae commonly known as sunflowers. Except for three South American species, the species of Helianthus are native to North America and Central America. The best-known species is the common sunflower. This and other species, notably Jerusalem artichoke, are cultivated in temperate regions and some tropical regions, as food crops for humans, cattle, and poultry, and as ornamental plants. The species H. annuus typically grows during the summer and into early fall, with the peak growth season being mid-summer.
Zantedeschia is a genus of eight species of herbaceous, perennial, flowering plants in the family Araceae, native to southern Africa from South Africa north to Malawi. The genus has been introduced on all continents except Antarctica. Common names include arum lily for Z. aethiopica and calla and calla lily for Z. elliottiana and Z. rehmannii, although members of the genus are neither true lilies of Liliaceae, true Arums, nor true Callas. The colourful flowers and leaves of both species and cultivars are greatly valued and commonly grown as ornamental plants.
Rubus odoratus, the purple-flowered raspberry, flowering raspberry, or Virginia raspberry, is a species of Rubus, native to eastern North America, from Nova Scotia west to Ontario and Wisconsin, and south along the Appalachian Mountains as far as Georgia and Alabama.
Conopholis americana, the American cancer-root, bumeh or bear corn, is a perennial, non-photosynthesizing parasitic plant. It is from the family Orobanchaceae and more recently from the genus Conopholis but also listed as Orobanche, native but not endemic to North America. When blooming, it resembles a pine cone or cob of corn growing from the roots of mostly oak and beech trees.
Senecio ampullaceus, also known as Texas ragwort, Texas squaw-weed, Texas groundsel, and Texas butterweed, is a species of Senecio in the family Asteraceae, receiving its Latin name ampullaceus from its flask shaped flower-head. It is recommended for landscape use in its native Texas.
Lactuca canadensis is a species of wild lettuce known by the common names Canada lettuce, Canada wild lettuce, and tall lettuce. Its true native range is not clear, but it is considered to be a native of the eastern and central parts of North America. It naturalized in the western part of the continent as well as in Eurasia.
Agoseris apargioides is a species in the family Asteraceae, is commonly called seaside agoseris or seaside false-dandelion. It is native to the Pacific coast of the United States from Washington to central California, where it grows primarily on coastal dunes.
Agoseris aurantiaca is a species of plant in the family Asteraceae, commonly called orange agoseris or mountain dandelion. It is widespread in western North America.
Perideridia lemmonii is a species of flowering plant in the family Apiaceae known by the common names Lemmon's yampah and tuni. It is native to the western United States, where it is known from southeastern Oregon, western Nevada, and the mountains of eastern California. It grows in meadows, forests, and other habitat. It is a perennial herb approaching one meter in maximum height, its slender, erect stem growing from usually a single small tuber about 1.5 centimeters long. Leaves near the base of the plant have blades up to 30 centimeters long divided into one or two pairs of leaflets, each of which may be subdivided. The inflorescence is a compound umbel of many spherical clusters of small white flowers. These yield ribbed, round or oblong-shaped fruits each under half a centimeter long.
Actaea arizonica is a species of flowering plant in the buttercup family known by the common name Arizona bugbane. It is endemic to Arizona in the United States, where it occurs in Coconino, Gila, and Yavapai Counties. Like some other species in genus Actaea, this plant was formerly included in the genus Cimicifuga.

It occurs as far west as Texas, and it has been recorded in California. Its common names include Florida betony, Florida hedgenettle, and rattlesnake weed. It has been called wild artichoke, but it is not closely related to artichoke. The plant was the Florida Department of Agriculture's "Weed of the Month" for February 2010.
