Alyssum simplex, commonly known as Simple Alison, Gold Dust, or European Madwort, is an annual herb native to the rocky, calcareous soils of Eurasia, including the Mediterranean region and temperate zones. It typically grows rapidly to a height and width of 0.5-1.5 feet (0.15-0.5 meters). Alyssum simplex displays clusters of small, bright yellow flowers that are quite showy, blooming profusely in the spring and continuing into summer. The plant has a compact, mounding form, making it an attractive ground cover or border plant.

This species is valued for its drought tolerance and ability to thrive in poor soils, making it a low-maintenance choice for gardeners. It is often used in rock gardens, as edging, or in containers for a splash of color. Alyssum simplex requires minimal care, preferring full sun exposure and well-drained sandy or loamy soils. It is also appreciated for its ability to attract beneficial insects such as bees and butterflies to the garden. While generally pest-free, it can be susceptible to fungal diseases in overly moist conditions.CC BY-SA 4.0
