Teucrium cossonii (Teucrium cossonii, syn. T. majoricum) is a superb, mat-forming sub-shrub from the Balearic Islands, prized above all else for its densely silver-woolly, intensely aromatic narrow foliage that spreads into a low, luminous carpet of silvery texture and quiet Mediterranean beauty. The narrow leaves are clothed in soft, dense silver-gray hairs that create an almost shimmering, reflective quality in full sun — catching and returning light with the same restrained elegance as lavender or artemisia, and providing a year-round foliage presence of genuine ornamental distinction. In late spring and early summer, small rosy-pink to soft purple flower spikes emerge above the silver mat for a delicate seasonal floral accent that complements rather than competes with the foliage as the primary ornamental feature.This professional-grade 4" plant arrives with a compact, well-established root system cultivated through professional horticultural practices — ready to spread and establish in its new home. Cossonii Germander thrives in full sun with sharp drainage and lean, dry soil — an outstanding performer in rock gardens, dry borders, Mediterranean-style landscapes, gravel gardens, and raised beds where its low, spreading silver foliage mat provides year-round textural contrast and exceptional structural value. Its naturally compact, spreading habit and aromatic silver foliage make it an invaluable design companion to green, burgundy, or chartreuse-leaved plants, and a dependable anchor for water-wise and xeriscape planting schemes. Intensely Silver-Woolly Aromatic Foliage: Densely silver-hairy narrow leaves form a luminous, shimmering foliage carpet of real ornamental distinction — providing rich textural contrast, a softly reflective silver presence, and genuine year-round value in rock gardens, gravel beds, and Mediterranean-style borders. Outstanding Water-Wise Performer: A true Mediterranean dry-garden specialist, Teucrium cossonii thrives in lean, dry, sharply drained soil with minimal supplemental irrigation once established — one of the most drought-tolerant and reliably low-maintenance silver foliage sub-shrubs available for sustainable, water-wise garden design. Rosy-Pink Summer Flower Spikes: Small but charming rosy-pink to soft purple flower spikes emerge above the silver foliage in late spring and early summer — adding a delicate, romantic floral accent that enriches the seasonal display and provides a welcome nectar source for bees and beneficial insects. Pollinator Friendly: The small flower spikes attract bees and beneficial insects reliably during the bloom period — adding meaningful ecological value to rock gardens, Mediterranean borders, and xeriscape plantings while contributing a critical early-season nectar source to the surrounding garden ecosystem. Deer & Rabbit Resistant: The strongly aromatic, silver-woolly foliage is naturally unappealing to browsing deer and rabbits — a reliable, low-effort defense that keeps the plant's attractive spreading silver mat consistently intact through the entire growing season without chemical intervention. These 4" healthy live plants thrive in full sun (6+ hours daily) with very well-drained, lean to average soil; excellent drainage is absolutely essential — avoid clay, rich fertile soils, and any standing water, all of which will significantly reduce plant health and longevity. Water sparingly once established; this plant strongly prefers dry conditions and thrives with minimal supplemental irrigation. USDA Hardiness Zones 7–9 (verify with grower); mature height: 4–8 inches; spread: 12–18 inches. Bloom time: late spring to early summer. A light trim after flowering maintains a tidy, compact mat and encourages fresh silver foliage growth through the remainder of the season.
