Symphyotrichum
''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 in eastern Eurasia. Several species have been introduced to Europe as garden specimens, most notably New England aster (''Symphyotrichum novae-angliae'') and New York aster (''Symphyotrichum novi-belgii''). Description Brouillet, et al. wrote: Taxonomy of ''Symphyotrichum'' is difficult. Species are usually heterophyllous, some strongly so. Individuals in the spring, with basal rosettes, often have leaf shapes quite different from those with cauline leaves seen later in the season. Phyllary shape on first- and later-formed heads may differ. Individuals may vary considerably in plant size and array development depending upon growing con ...

List Of Symphyotrichum Species
''Symphyotrichum'' is a genus of flowering plants in the tribe Astereae which includes the commonly cultivated New York aster ('' S. novi-belgii'') and New England aster ('' S. novae-angliae''). Its species are widespread in the Americas, including as far north as subarctic North America to as far south as Chile, Argentina, and the Falkland Islands. One species has a native range extending into eastern Eurasia. Most of the species in the genus are perennials. The flower heads have white, pink, purple, or blue ray florets surrounding white to yellow disk florets. The disk floret corollas become pink, purple, or brown after pollination. The three species in section ''Conyzopsis'' have reduced or absent ray florets. ''Symphyotrichum'' is the type genus of subtribe Symphyotrichinae. There are 98 species in the genus, some with varieties, and thirteen named hybrids. The genus is split into five subgenera: ''Chapmaniana'', ''Astropolium'', ''Virgulus'', ''Ascendentes'', and ''S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Symphyotrichum Novae-angliae
(formerly ''Aster novae-angliae'') is a species of flowering plant in the aster family (Asteraceae) native to central and eastern North America. Commonly known as , , or , it is a perennial, herbaceous plant usually between tall and wide. The usually deep purple flowers have up to 100 ray florets which are rarely pink or white. These surround the flower centers which are composed of just as many tiny yellow disk florets. The plant grows naturally in clumps, with several erect stems emerging from a single point. The stems are stout, hairy, and mostly unbranched. The untoothed, lance-shaped leaves clasp the stem with earlobe-like appendages, and the lower stem leaves often wither by the time of flowering. New England aster generally grows in wet environments but also has been found in dry soil or sand. The seeds and nectar of this mostly conservationally secure species, which blooms August to November, are important to a wide variety of animals, including birds, bees, an ...

Symphyotrichum Ericoides
''Symphyotrichum ericoides'' (formerly ''Aster ericoides''), known as white heath aster, frost aster, or heath aster, is a species of flowering plant in the family Asteraceae native to much of central and eastern North America. It has been introduced to parts of Europe and western Asia. The naturally-occurring hybrid species of white heath aster and New England aster (''Symphyotrichum novae-angliae'') is named ''Symphyotrichum'' × ''amethystinum'' and is commonly known as amethyst aster. It can grow where the two parents are in close proximity. Description Heath aster is a perennial herbaceous plant with stems from tall. Its leaves are sessile (stalkless) and narrow, becoming smaller towards the top of the plant and tips of the branching stem. It has white (rarely pinkish), composite flowerheads with yellow centers that begin flowering in late summer and last through fall. They are across. It is commonly confused with ''Symphyotrichum pilosum'', which co-occurs throughout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Symphyotrichum Novi-belgii
''Symphyotrichum novi-belgii'' (formerly ''Aster novi-belgii''), commonly called New York aster, is a species of flowering plant. It is the type species for '' Symphyotrichum'', a genus in the family Asteraceae, whose species were once considered to be part of the genus ''Aster''. Plants in both these genera are popularly known as Michaelmas daisy because they bloom around September 29, St. Michael’s Day. The Latin specific epithet ''novi-belgii'' (literally "New Belgium") refers not to modern Belgium, but the 17th century Dutch colony New Netherland which was established on land currently occupied by New York state (as '' Belgica Foederata'' was the Latin term for the United Netherlands at the time). ''Symphyotrichum novi-belgii'' grows in abandoned fields and wet meadows in eastern Canada and the northeastern United States.

Cauline
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (adaxial) and lower (abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs ligh ...

Aster (genus)
''Aster'' is a genus of perennial flowering plants in the family Asteraceae. Its circumscription has been narrowed, and it now encompasses around 170 species, all but one of which are restricted to Eurasia; many species formerly in ''Aster'' are now in other genera of the tribe Astereae. ''Aster amellus'' is the type species of the genus and the family Asteraceae. The name ''Aster'' comes from the Ancient Greek word (''astḗr''), meaning "star", referring to the shape of the flower head. Many species and a variety of hybrids and varieties are popular as garden plants because of their attractive and colourful flowers. 'Aster' species are used as food plants by the larvae of a number of Lepidoptera species—see list of Lepidoptera that feed on ''Aster''. Asters can grow in all hardiness zones. Circumscription The genus ''Aster'' once contained nearly 600 species in Eurasia and North America, but after morphologic and molecular research on the genus during the 1990s, it was ...
