Buphthalmum is a genus of flowering plants in the aster family, Asteraceae. [3] They are native to Europe, and B. salicifolium is in cultivation and has been introduced elsewhere. [4] [5]
These are perennial herbs with alternately arranged leaves. The inflorescence is a solitary flower head atop the stem. The head has very narrow phyllaries, yellow ray florets and yellow disc florets. The fruit is a cypsela usually tipped with a pappus of scales; those growing from the ray florets may lack pappi. [4]
The following species are recognised in the genus Buphthalmum: [6]
Callistephus is a monotypic genus of flowering plants in the aster family, Asteraceae, containing the single species Callistephus chinensis. Its common names include China aster and annual aster. It is native to China and Korea. and it is cultivated worldwide as an ornamental plant in cottage gardens and as a cut flower.
Leucanthemum is a genus of flowering plants in the aster family, Asteraceae. It is mainly distributed in southern and central Europe. Some species are known on other continents as introduced species, and some are cultivated as ornamental plants. The name Leucanthemum derives from the Greek words λευκός – leukos ("white") and ἄνθεμον – anthemon ("flower"). Common names for Leucanthemum species usually include the name daisy, but "daisy" can also refer to numerous other genera in the Asteraceae family.
Bidens frondosa is a North American species of flowering plant in the aster family, Asteraceae. It is widespread across much of Canada, the United States, and Mexico It is known in many other parts of the world as an introduced species, including Europe, Asia, Morocco, and New Zealand. Its many common names include devil's beggarticks, devil's-pitchfork, devil's bootjack, sticktights, bur marigold, pitchfork weed, tickseed sunflower, leafy beggarticks, and common beggar-ticks.
Symphyotrichum is a genus of over 100 species and naturally occurring hybrids of herbaceous annual and perennial plants in the composite family, Asteraceae, most which were formerly treated within the genus Aster. The majority are endemic to North America, but several also occur in the West Indies, Central and South America, as well as one species in eastern Eurasia. Several species have been introduced to Europe as garden specimens, most notably New England aster and New York aster.
Erigeron acer is a widespread species of herbaceous flowering plant in the family Asteraceae. Common names include bitter fleabane and blue fleabane. The species is native to Canada, colder parts of the United States, northern, central, and southeastern Asia, and most of Europe.

Heteranthemis is a monotypic genus of plants in the daisy family containing the single species Heteranthemis viscidehirta, which is known by the common name oxeye, or sticky oxeye. This plant is native to the Iberian Peninsula and adjacent areas in North Africa, but it can be found in other parts of the world as an introduced species. This is an annual herb growing erect stems 20 to 80 centimeters tall. Its abundant leaves are a few centimeters long, wavy to curly and divided into irregular toothed lobes. The stem and foliage are glandular and produce a sticky exudate. The plants produce bright yellow daisylike flower heads, with bases covered in large green phyllaries. The center of the head is filled with many yellow disc florets and the edge is fringed with toothed yellow ray florets about 2 centimeters long.
Leontodon saxatilis is a species of hawkbit known by the common names lesser hawkbit, rough hawkbit, and hairy hawkbit. It is native to Europe and North Africa but can be found in many other places across the globe as an introduced species and often a noxious weed. This is a dandelion-like herb growing patches of many erect, leafless stems from a basal rosette of leaves. The leaves are 2 to 15 centimeters long, 0.5 to 2.5 centimeters wide, entire or lobed, and green in color. Atop the stems are solitary flower heads which are ligulate, containing layered rings of ray florets with no disc florets. The florets are yellow with toothed tips. The fruit is a cylindrical achene with a pappus of scales. Fruits near the center of the flower head are rough, while those growing along the edges of the head are smooth.
Calendula arvensis is a species of flowering plant in the daisy family known by the common name field marigold. It is native to central and southern Europe, and it is known across the globe as an introduced species.
Corethrogyne is a monotypic genus of flowering plant in the family Asteraceae. Its only species is Corethrogyne filaginifolia, known by the common names common sandaster and California aster.
Chrysogonum is a genus of flowering plants in the family Asteraceae. As of May 2024, two circumscriptions of the genus were in use. In the broader circumscription, the genus has a discontinuous distribution, with species native to eastern North America and Madagascar. In the narrower circumscription, the genus contains only species native to eastern North America.
Chrysanthemum × morifolium (also known in the US as florist's daisy and hardy garden mum, is a hybrid species of perennial plant in the genus Chrysanthemum of the Asteraceae family.
Symphyotrichum dumosum is a species of flowering plant of the family Asteraceae commonly known as rice button aster and bushy aster. It is native to much of eastern and central North America, as well as Haiti and Dominican Republic. It is a perennial, herbaceous plant that may reach a height of 1 meter.
Crepis foetida is a European species of flowering plant in the family Asteraceae with the common name stinking hawksbeard. It is widespread across much of Europe and Siberia, as well as being sparingly naturalized in scattered locations in the United States and Australia.
Oedera capensis is a prickly shrublet belonging to the family Asteraceae. It has stems that branch only at the foot and are densely set over their entire length with narrowly triangular leathery leaves with a sharp tip at approximately right angles to the stem. At their tip are what at first sight appears to be a single flowerhead with yellow ray florets and yellow disc florets. In fact, these are mostly nine densely cropped heads, as is suggested by the nine domes of the "disc" of the composite head, the untidy arrangement of the ray florets, and becomes very clear when cutting through the composite head. It is an endemic of the south of the Western Cape province in South Africa.
Symphyotrichum praealtum, known as willowleaf aster and willow aster, is a species of flowering plant in the aster family Asteraceae. It is native to North America and introduced in Europe.

It is native to south Texas, Mexico, Belize, Venezuela, and the Caribbean. It has also been introduced east of Texas, Argentina, Hawaii, India, Java, Australia, and Taiwan. It is one of only three species in the genus Calyptocarpus.
Garden marguerites, also known as marguerite daisies, are cultivars of plants in the subtribe Glebionidinae of the family Asteraceae, the great majority being hybrids created in cultivation. One of the genera belonging to the subtribe, Argyranthemum, was introduced into cultivation from the Canary Islands in the 18th century, and modern cultivars are mostly sold and grown under the genus name Argyranthemum or the species name Argyranthemum frutescens, although many are actually intergeneric hybrids. The first such hybrids involved species now placed in the genus Glebionis, but other crosses within the subtribe are known. Breeding has aimed at introducing flower heads in varied colours and shapes while retaining the shrubby habit of Argyranthemum. Garden marguerites are used as summer bedding or grown in containers. Most are only half-hardy. They can be trained into shapes such as pyramids or grown as standards.
Symphyotrichum racemosum is a species of flowering plant native to parts of the United States and introduced in Canada. It is known as smooth white oldfield aster and small white aster. It is a perennial, herbaceous plant in the family Asteraceae. It is a late-summer and fall blooming flower.
