According to Auders & Spicer (2012) this is ‘An irregularly shaped creeping plant that lies over itself, with thickly arrayed, long silvery bluish foliage. The occasional upright growing limb or branch should be removed to keep it flat-growing. In ten years 0.3 x 1.8 m’. An illustration from Hatch (2018–2020), shows a number of plants growing outside the conservatory at Brookside Gardens, Marlyland, making spreading, glaucous mounds. It was introduced in 1979 by the Iseli Nursery, Oregon (Auders & Spicer 2012).
