About Alyssum simplex
Alyssum simplex, commonly known as alyssum or rock alyssum, is a small annual or perennial herbaceous plant from the Brassicaceae family, valued for its abundant tiny white or yellow flowers. It forms dense, creeping or erect mats, creating a floral carpet that is ideal for rock gardens, path edges, or as ground cover in Mediterranean gardens. Its delicate appearance and prolonged flowering make it perfect for enhancing spaces with a wild and charming touch.
Native range
Mediterranean regions, Europe, and temperate Asia.
Care tips
It requires full sun for optimal flowering, although it toler tolerates some partial shade in very hot climates. Watering should be moderate, allowing the substrate to dry slightly between waterings, as it is sensitive to waterlogging. It prefers well-drained soils, preferably sandy or stony, with a neutral to slightly alkaline pH. A common mistake to avoid is overwatering, which can lead to root rot and plant death.
