Description

This erect and sparsely branched shrub grows to be up till 1.6 m (5.2 ft) tall. [1] The oval shaped and alternately arranged leaves grow directly on the stem or on short stems. They have finely toothed margins. The upper surface is hairless while the lower surface is densely covered in felt-like white or grey hairs. [1] Flowers are present between December and May. Dense flowerheads grow on the ends of branches and are surrounded by many rows of hairy bracts. [1] The ray (outer) florets are white or purple. The disc inner) florets are white, yellow or purple. The outer layer of floral leaves are covered in bristles. The brown seeds are conical, ribbed and hairy. [1]

Distribution and habitat

This species grows in South Africa. [2] It grows in damp areas, commonly near rivers and streams. It grows on rocky grasslands on mountain slopes. [1]

<i>Emilia sonchifolia</i> Species of plant

Emilia sonchifolia, also known as lilac tasselflower or cupid's shaving brush, is tropical flowering species of tasselflower in the sunflower family. It is widespread in tropical regions around the world, apparently native to Asia and naturalized in Africa, Australia, the Americas, and various oceanic islands.

<i>Eurybia divaricata</i> North American species of flowering plant

Eurybia divaricata, the white wood aster, is an herbaceous plant native to eastern North America. It occurs in the eastern United States, primarily in the Appalachian Mountains, though it is also present in southeastern Canada, but only in about 25 populations in the provinces of Ontario and Quebec. In the U.S. it is abundant and common, but in Canada it is considered threatened due to its restricted distribution. It has been introduced to a number of countries in Europe. It can be found in dry open woods as well as along wood-edges and clearings. The species is distinguished by its flower heads that have yellow centers and white rays that are arranged in flat-topped corymbiform arrays, emerging in the late summer through fall. Other distinguishing characteristics include its serpentine stems and sharply serrated narrow heart-shaped leaves. The white wood aster is sometimes used in cultivation in both North America and Europe due to it being quite tough and for its showy flowers.

<i>Cirsium eriophorum</i> Species of plant

Cirsium eriophorum, the woolly thistle, is a herbaceous biennial species of flowering plant in the genus Cirsium of the family Asteraceae. It is widespread across much of Europe. It is a large biennial plant with sharp spines on the tips of the leaves, and long, woolly hairs on much of the foliage. The flower heads are large and nearly spherical, with spines on the outside and many purple disc florets but no ray florets.

<i>Polyarrhena</i> Genus of plants

Polyarrhena is a genus of low, branching shrublets that is assigned to the daisy family. Its stems are alternately and densely set with entire or somewhat toothed leaves. Like in almost all Asteraceae, the individual flowers are 5-merous, small and clustered in typical heads, and which are surrounded by an involucre of in this case three whorls of bracts. In Polyarrhena, the centre of the head is taken by yellow disc florets, and is surrounded by one single whorl of white ligulate florets that have a pinkish-purple wash on the underside. These florets sit on a common base and are not individually subtended by a bract. The species occur in the Cape Floristic Region. Polyarrhena reflexa has long been cultivated as an ornamental and is often known under its synonym Aster reflexum.

<i>Pterocaulon sphacelatum</i> Species of plant

Pterocaulon sphacelatum, commonly known as apple bush or fruit-salad plant, is a species of flowering plant in the family Asteraceae. It is an upright shrub with mostly pink to purple flowers and is endemic to Australia.

Remarkable for species in the daisy family, each flower head contains just one, bisexual, mauve, pink or white disc floret within a sheath consisting of just two large involucral bracts. The species are all endemic to the Cape Floristic Region of South Africa, where they are known as plampers.

<i>Felicia</i> (plant) Genus of shrublets, perennials and annuals in the daisy family

Felicia is a genus of small shrubs, perennial or annual herbaceous plants, with 85 known species, that is assigned to the daisy family. Like in almost all Asteraceae, the individual flowers are 5-merous, small and clustered in typical heads, and which are surrounded by an involucre of, in this case between two and four whorls of, bracts. In Felicia, the centre of the head is taken by yellow, seldom whitish or blackish blue disc florets, and is almost always surrounded by one single whorl of mostly purple, sometimes blue, pink, white or yellow ligulate florets and rarely ligulate florets are absent. These florets sit on a common base and are not individually subtended by a bract. Most species occur in the Cape Floristic Region, which is most probably the area where the genus originates and had most of its development. Some species can be found in the eastern half of Africa up to Sudan and the south-western Arabian peninsula, while on the west coast species can be found from the Cape to Angola and one species having outposts on the Cameroon-Nigeria border and central Nigeria. Some species of Felicia are cultivated as ornamentals and several hybrids have been developed for that purpose.
