About Sonchus maritimus
Sonchus maritimus, commonly known as Sea Sowthistle, is a robust perennial herbaceous plant native to coastal areas and salt marshes. Its lobed leaves and bright yellow, dandelion-like flowers add a touch of color and wildness to coastal gardens or wetland areas. It is ideal for dune revegetation or as a low-maintenance plant in saline environments.
Native range
Mediterranean region of Europe and North Africa, extending to Asia Minor.
Care tips
This species thrives in full sun in moist, preferably saline or brackish soils, tolerating wind exposure and sea spray. Watering should be regular to keep the substrate consistently moist, especially in hot, dry climates. Use a sandy substrate with good drainage that still retains moisture, similar to natural coastal environments. A common mistake is attempting to grow it in low-salt soils or indoors, where it will not thrive.
How to save a dying Sonchus maritimus

- What kills it
- Excessive salinity or lack of moisture in coastal environments. Also waterlogging if drainage is poor.
- Can it be saved?
- Yes, if you act quickly. It's a resilient plant, but needs water and salt balance.
