Yellow salsify is native to southern and central Europe and western Asia. It was introduced in the early 1900s to North America, where it has spread widely. In many areas it is considered an invasive. It grows almost anywhere there is ample sunlight and medium to dry conditions, though plants are usually scattered, not densely clustered.
Flowers: Flowers are 1½-2" (4-6 cm) in diameter, forming from tall, tapered, blue-green buds. Flowers open in the morning and close in the afternoon. They appear from late spring to early summer. Sharp, starlike green bracts appear behind the flowerhead, and are longer and more prominent than in other salsifies.
Fruits: Produces a round pappus (seedhead) up to 4" (10 cm) around, similar to dandelions. The seedhead is like a pincushion filled with of achenes, each ⅞-1½" (2.5-4 cm) long, equipped with its own tiny “pararchute.”
Edibility: Roots are technically edible, cooked or even raw, but the plant is not generally consumed. The roots are said to taste similar to oysters, hence the common name wild oysterplant.
