About Hoary mustard
Erysimum incanum, known as Vélar blanchi or Vélar blanc, is a perennial herbaceous plant from the Brassicaceae family, valued for its silvery foliage and bright yellow flowers that emerge in spring. Its compact habit and hardiness make it ideal for rockeries, garden borders, or as a potted plant, adding a touch of color and texture. It's an excellent choice for low-maintenance or xeriscaping gardens.
Native range
Central and Southern Europe, and North Africa.
Care tips
It thrives in full sun exposure for optimal flowering and denser foliage. Moderate watering is required, allowing the substrate to dry out completely between waterings, as it is sensitive to overwatering. Use a well-draining substrate, preferably sandy or with gravel. A common mistake is overwatering, which can lead to root rot.
