Species of flowering plant

Tragopogon dubius, commonly known as yellow salsify, western salsify, or goatsbeard, is a species of flowering plant in the family Asteraceae. It is native to Europe and has been introduced to North America, where it is now widespread.

Description

Tragopogon dubius is a biennial plant that can grow up to 120 cm tall. It has a thick taproot and a hollow stem. The leaves are long, narrow, and grass-like, with a bluish-green color. The plant produces large, yellow, dandelion-like flowers that are about 5 cm in diameter. These flowers open in the morning and close by midday. The seed head is a large, spherical puffball, similar to that of a dandelion, which aids in wind dispersal of the seeds.

Distribution and habitat

Tragopogon dubius is native to southern and central Europe but has spread to other parts of the world, including North America. It is commonly found in fields, roadsides, and disturbed areas. The plant prefers well-drained soils and can tolerate dry conditions.

Ecology

The flowers of Tragopogon dubius are visited by a variety of pollinators, including bees and butterflies. The plant is known for its ability to thrive in disturbed habitats, which has contributed to its spread in non-native regions.

Uses

The roots of Tragopogon dubius are edible and have been used as a food source. They can be eaten raw or cooked and are sometimes used in salads or soups. The plant has also been used in traditional medicine for its purported health benefits.

+'''''Tragopogon dubius''''', commonly known as yellow salsify, western salsify, or goatsbeard, is a species of flowering plant in the family [[Asteraceae]]. It is native to [[Europe]] and has been introduced to [[North America]], where it is now widespread.
-'''Tragopogon dubius''' is a biennial plant, which means it completes its lifecycle over two years. In the first year, it forms a rosette of leaves at ground level, and in the second year, it sends up a flowering stem. The leaves are long and narrow, similar to those of a dandelion. The flowers are large and yellow, with a typical daisy-like appearance. They open in the morning and close in the afternoon, hence the plant's other common name, the "Jack-go-to-bed-at-noon". The fruit is a large, round, wind-dispersed seed head, similar to a dandelion 'clock'.
