About Flixweed
Descurainia sophia, commonly known as flixweed or tansy mustard, is an annual or biennial plant belonging to the Brassicaceae family. It is characterized by its finely divided leaves and small, pale yellow flowers, followed by elongated seed pods. Although often considered a weed, its delicate foliage can add textural interest in wild or naturalized garden settings.
Native range
Europe, Asia, and North Africa
Care tips
This plant prefers full sun and tolerates a wide range of soils, though it thrives in well-drained, slightly alkaline conditions. It requires little watering once established, being quite drought-tolerant. Avoid over-fertilization, as it can promote weak foliar growth at the expense of flowering. A common mistake is underestimating its self-seeding capability, which can lead to unwanted proliferation if seed dispersal is not managed.
How to save a dying Flixweed
- Warning signs
- Yellowish or whitish leaves, weak and drooping stems, stunted growth. Premature flowering may occur.
- First aid
- Move it to a bright indirect light spot. Check soil moisture; water only if dry to the touch. Consider repotting if soil is compacted.
- What kills it
- Overwatering (root rot) or extreme lack of light. Also, non-specific herbicides or pesticides.
- Can it be saved?
- Yes, if roots are not completely rotted and some green leaves or shoots remain. It's resilient but needs care.
