Hymenoxys Hoopesii
''Hymenoxys hoopesii'' (formerly ''Dugaldia hoopesii'') is a species of flowering plant in the daisy family known by the common names owl's claws, orange sneezeweed, and yerba del lobo. It is native to the western United States, where it grows in habitats of moderate elevation, such as mountain meadows in the Rocky Mountains, Sierra Nevada, southern Cascades, and other ranges. It has been found from Arizona, New Mexico, and central California north as far as Montana and Oregon. ''H. hoopesii'' is an erect perennial herb growing up to about 1 meter (40 inches) in height, with smooth-edged leaves up to long, oval on the lower stem and lance-shaped toward the top. Blooming from July to September, the inflorescence bears several flower heads on erect peduncles, each lined with a base of hairy, pointed phyllaries. The flower head is up to wide and has a center of 100–325 tiny disc florets fringed with 14–26 orange or yellow ray florets, each ray up to long. The fruit is an ache ...

''Achillea ptarmica'' is a European species of herbaceous perennial flowering plant in the genus ''Achillea'' of the daisy family Asteraceae. Common names include the sneezewort, sneezeweed, bastard pellitory, European pellitory, fair-maid-of-France, goose tongue, sneezewort yarrow, wild pellitory, and white tansy. It is widespread across most of Europe and naturalized in scattered places in North America. It is native to Europe and western Asia. ''Achillea ptarmica'' has loose clusters of showy white composite flower heads that bloom from June to August. Its dark green leaves have finely toothed margins. Like many other plants, the sneezewort's pattern of development displays the Fibonacci sequence. The name ''ptarmica'' comes from the Greek word ''ptairo'' (=sneeze) and means 'causes sneezing'. Uses Leaves can be eaten raw or cooked. ''Achillea ptarmica'' yields an essential oil that is used in herbal medicine. The leaves are used as an insect repellent. When chewed, the p ...

Helenium
''Helenium'' is a genus of annuals and herbaceous perennial plants in the family Asteraceae, native to the Americas. They bear yellow or orange daisy-like composite flowers. A number of these species (particularly ''Helenium autumnale'') have the common name sneezeweed, based on the former use of their dried leaves in making snuff. It was inhaled to cause sneezing that would supposedly rid the body of evil spirits. Larger species may grow up to tall. The genus is named for Helen of Troy, daughter of Zeus and Leda. ''Helenium'' species are used as food plants by the larvae of some Lepidoptera species including ''Phymatopus behrensii''. Genus level properties: most conspicuously globe-like disk-shaped flowers, rays three-lobed at tip. Species Cultivation Numerous cultivars have been developed for garden use - mainly from ''H. autumnale'' and ''H. bigelovii''. They are useful for late summer and fall bloom, usually in less formal compositions. They are appropriate for nati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...
