About Onopordum candidum
Onopordum candidum, commonly known as the white thistle or Moroccan thistle, is a striking biennial or short-lived perennial native to North Africa and Southern Europe. It is notable for its woolly, silvery, spiny foliage and large, purple-pink flowers that attract pollinators. It is ideal for Mediterranean-style gardens, xeriscaping, or as a focal point in sunny borders.
Native range
Caucasus, Turkey, and the Middle East
Care tips
It requires full sun for optimal growth and well-drained soil, preferably sandy or rocky, as it is highly susceptible to waterlogging. Watering should be moderate once established, as it tolerates drought well; avoid overwatering at all costs. A common mistake is planting it in heavy or clay soils that retain too much moisture, which can lead to root rot.
