Marrubium rotundifolium

Silver-edged Horehound

USDA Zone: 4-9

Plant number: 1.355.070

This native of Turkey forms a dense patch of small rounded velvety leaves, each lined along the edges and undersides with silvery white. A tough plant for hot and dry western regions, suitable for the rock garden or edging pathways. Flowers are insignificant. A vigorous, low maintenance plant if soil drainage is good. Not well suited to regions with hot and humid summers, since the plants may begin to rot out. Shear off the flowers, if desired. A nice textural companion to blue or silver-leaved grasses, perennials and shrubs. Semi-evergreen. Plants may be sheared lightly in spring or after blooming, if desired.
