Quietly beautiful, softly textured, and wonderfully adapted to dry conditions, Marrubium supinum is a drought-tolerant perennial that forms a dense, silvery cushion of woolly gray foliage. Its low, glowing form brings year-round texture to rock gardens, gravel gardens, water-wise landscapes, sunny borders, and Mediterranean-style plantings. From late spring into summer, delicate creamy-white flowers appear in tidy clusters above the foliage, adding subtle beauty while attracting bees and beneficial insects.

Growing approximately 6 to 12 inches tall and spreading 18 to 24 inches wide, Marrubium supinum is a beautiful choice for edging, troughs, dry garden plantings, sunny slopes, and well-drained spaces where a refined, low-growing perennial can shine. Its silver foliage pairs wonderfully with purple salvias, blue verbenas, pink dianthus, lavender, yarrow, ornamental grasses, thyme, and other drought-tolerant plants that create a soft, layered, water-wise garden scene.

Plant Marrubium supinum in full sun with lean, well-drained soil and little supplemental water once established. Avoid overly rich soil or wet conditions, as this resilient perennial performs best where drainage is excellent. Tough, refined, and remarkably low-maintenance, it brings lasting structure, pollinator appeal, and quiet elegance to dry garden designs.
