Phlomis russeliana

An outstanding groundcover forming lush gray-green foliage from crowns that expand via short rhizomes. The dense patches effectively suppress weeds. Yellow flowers arranged in whorls and layers develop from tightly packed green buds that open sequentially, drying in place when finished. The whorls persist through summer and autumn, turning tan.

Remarkably persistent through winter with whorls remaining intact through snow, rain, and storms. One of few plants maintaining structure all winter. Native to Turkish clearings and deciduous woodland edges. RHS Award of Garden Merit and Great Plant Pick. Excellent for banks with moisture-retentive soil.
