Tragopogon pratensis, commonly known as Jack-go-to-bed-at-noon or meadow salsify, is a biennial herb native to grasslands, meadows, and fields across Europe and extending into North Africa and Western Asia. It has been introduced to North America, where it grows in similar habitats such as fields and roadsides. This plant typically reaches up to 30 inches in height and features grass-like leaves. Its distinctive yellow flowers open in the morning and often close by noon, hence the common name. The flowering season is from late spring to early summer, and the flowers are moderately showy. After flowering, it forms a large, dandelion-like seed head. Meadow salsify produces a milky latex and has edible roots and buds that are sometimes used in traditional European cuisines.

Meadow salsify is appreciated for its unique flowering behavior and edible parts, which can be a conversation starter in a garden setting. It is also used in wildflower meadows and naturalistic plantings. In cultivation, it prefers full sun to partial shade and can tolerate a range of soil types, provided they are well-drained. It requires minimal maintenance and is drought-tolerant once established. However, gardeners should be cautious as Tragopogon pratensis can be potentially invasive in some regions, spreading by seed and outcompeting native vegetation.CC BY-SA 4.0
