About Dusty miller
Jacobaea ambigua, also known as Etna ragwort, is an attractive perennial plant from the Asteraceae family, valued for its silvery, finely divided foliage. It forms a dense mound of velvety leaves that give it a distinctive ornamental appearance. It is ideal for rockeries, sunny borders, or as a contrasting plant in pots, adding texture and color to any garden.
Native range
Mediterranean region, especially in Italy and Sicily.
Care tips
It requires full sun exposure to maintain its silvery and compact foliage. Watering should be moderate, allowing the substrate to dry completely between waterings, as it is sensitive to overwatering. It thrives in well-drained soils, preferably sandy or stony, with low organic content. A common mistake is overwatering, which can lead to root rot.
