Tragopogon dubius

Tragopogon dubius, also known as the Yellow Salsify, Western Salsify, or Wild Oysterplant, is a species of flowering plant in the Asteraceae family. It is native to Mediterranean regions of Europe but has been introduced to North America, where it has spread widely across the continent.

Description

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'.

Distribution and habitat

Tragopogon dubius is native to the Mediterranean region of Europe but has been introduced to other parts of the world, including North America, where it is now widespread. It is typically found in disturbed habitats, such as roadsides, fields, and waste places.

Uses

While not widely used today, Tragopogon dubius has a history of use as a food plant. The roots can be eaten raw or cooked, and have a sweet, oyster-like flavor, hence the common name "Wild Oysterplant". The young shoots and leaves can also be eaten, either raw in salads or cooked like spinach.

Cultivation

Tragopogon dubius is a hardy plant that can grow in a variety of soil types, although it prefers well-drained soil. It is drought-tolerant and can grow in full sun to partial shade. It is not commonly cultivated, but can be grown from seed and is often found in wildflower seed mixes.
