Some plants are pretty. This one is both beautiful and wonderfully useful. Cotton Lavender—also known as Grey Santolina or Lavender Cotton—is a compact, rounded evergreen shrub with extraordinary, finely textured foliage. Its dense mound of narrow, almost coral-like leaves is a stunning silvery-grey to grey-green, covered in a soft, woolly down. Brush against them, and you’ll release a strong, distinctive, pleasantly pungent, musky fragrance. In summer (typically July to August), slender, leafless stalks rise bearing an abundance of small, perfectly round, button-like flower heads in bright golden-yellow, hovering above the silver foliage like tiny sunny buttons.
Native to the western and central Mediterranean, this tough plant is perfectly suited to the Western Cape’s winter-rainfall climate. It thrives in full sun—at least 6 hours of direct light for the best silver colour and compact shape—and demands very well-drained, even poor, sandy or gritty soil. Once established, it’s remarkably drought-tolerant and water-wise, handling coastal winds easily and is exceptionally frost-hardy (to about -15°C). Reaching 40–60cm tall and 60–100cm wide, it’s perfect for Mediterranean gardens, rockeries, borders, low hedges, or containers.
Key Features:
- Finely textured, aromatic, silvery-grey foliage for year-round structure
- Bright golden-yellow button-like flowers in summer for cheerful contrast
- Exceptionally drought-tolerant and frost-hardy once established
- Attracts bees and butterflies; fragrant foliage repels some pests
Gardening Note: Plant in well-drained soil in full sun for the best silver colour and compact growth. Water regularly until established; mature plants are highly drought-tolerant and prefer to dry out between waterings. Avoid overwatering or heavy, wet soils—wet feet are fatal. Prune back lightly after flowering to maintain a tidy shape and prevent legginess.
