Nursery contributed plant descriptions

Super soft & super tough, Plectranthus cremnus can deal with pretty much anything you throw at it. Salt spray, high winds, heat, fog, light frost, deer & drought, no problem! Fragrant & fuzzy silvery grey foliage stays a low 6” & spreads to a lovely weed suppressing mat. Lovely lavender flower spikes bloom year round. The only requirement for happiness is good drainage. Endemic to Australia’s New South Wales northern coast. Thank you to UC-Berkeley’s Botanical Garden for sharing this brawny rare beauty with us!
