About Common ragweed
Ambrosia artemisioides, commonly known as beach wormwood, is a perennial herbaceous plant native to Mediterranean coastlines. It is characterized by its finely divided, silvery-grey foliage, which gives it an ethereal appearance and a soft texture. It is ideal for coastal gardens, rockeries, or as a border plant, bringing a touch of color and resilience to harsh environments.

Care tips
This plant prefers full sun to develop its most intense silvery coloration and bloom properly. It is extremely drought-tolerant and only requires occasional watering once established; overwatering is a common mistake that can lead to root rot. It thrives in well-drained soils, even poor or sandy ones, and does not require frequent fertilization. Avoid planting it in areas with excessive shade or constant humidity.
