About Onopordum carduelium
The Tenteniguada Thistle (Onopordum carduelium) is a biennial or perennial herbaceous plant belonging to the Asteraceae family, endemic to the Canary Islands. It is characterized by its large rosettes of spiny, greyish-green leaves and robust floral stems that can reach up to 2 meters in height, topped with striking purple flowers. It is ideal for low-maintenance gardens, xeriscaping, or as an ornamental plant in areas with a Mediterranean climate, adding a wild and structural touch.

Care tips
It requires full sun for optimal development and prefers well-drained soils, even poor or rocky ones, adapting well to dry conditions. Watering should be scarce once established, as it tolerates drought well; overwatering is the most common mistake and can lead to root rot. It does not require frequent fertilization and is resistant to most pests and diseases. Avoid transplanting once it has developed a good root system.
