About Star thistle
Carthamus creticus, commonly known as woolly distaff thistle, is a robust annual or biennial plant belonging to the Asteraceae family, native to the Mediterranean region. It is characterized by its spiny stems and leaves covered in whitish woolly hairs, culminating in striking yellow or orange thistle-like flowers. It is ideal for rock gardens, sunny borders, and naturalized landscapes where its hardiness and vibrant bloom can stand out.

Care tips
This species thrives in full sun exposure to ensure abundant flowering. It is very drought-tolerant once established, so watering should be moderate, allowing the substrate to dry out completely between waterings. It prospers in well-drained, even poor or sandy soils; good drainage is crucial to prevent root rot. A common mistake is overwatering, especially in heavy soils, which can be fatal to the plant.

- What kills it
- Overwatering and lack of direct sun are its worst enemies. It cannot tolerate shade or constant humidity.
