Yellow Salsify, one of the yellow flowered weeds, comes from Europe, and people have introduced it to North America and other regions. You can commonly spot it in open areas, fields, and roadsides. Bright yellow flowers that resemble dandelions precede its fluffy seed heads.

Yellow Salsify roots have a delicate, sweet, and nutty flavor, often compared to oysters or artichokes. You can cook and eat the roots as a vegetable, roast them, or use them in soups and stews. You can also eat the young leaves of Yellow Salsify and use them in salads or cook them as greens.

Additionally, you can collect the fluffy seed heads that the plant produces and use them as a natural tinder for starting fires. People consider Yellow Salsify safe and edible for both humans and animals, valuing it for its unique taste and culinary versatility.

50. Yellow Toadflax (Linaria vulgaris)

People native to Europe originally grew Yellow Toadflax, but they have since introduced it to North America and other parts of the world. This yellow flowered weed thrives in open areas, roadsides, and disturbed habitats. Its bright yellow flowers grow in dense spikes, creating a vibrant display.

I do not recommend Yellow Toadflax for consumption by humans or animals. The plant contains bitter compounds, including glucosides and alkaloids, which can cause gastrointestinal upset or other adverse effects.

It is important to avoid ingestion or contact with Yellow Toadflax to prevent any potential toxicity.

These resilient weeds offer not only visual charm but also play important roles in supporting pollinators, enriching the soil, and contributing to the overall biodiversity of our ecosystems.

While some yellow flowered weeds delight our taste buds with their edible leaves, flowers, or roots, caution is necessary.
