Marrubium rotundifolium Silver Edged Horehound is one our very best xeric groundcovers for poor soil areas with hot, sunny growing conditions. The soft felted leaves are green with a bright silver underside that curls up to give the leaves a silver edge. Drought resistant/drought tolerant plant (xeric).
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low
temperatures; the lower the zone number the colder the winter.
If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will
survive the winter temperatures in your area.
If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack
of freezing winter temperatures do not provide a time for winter dormancy (rest).
2009 Plant Select Winner 10" tall x 18" wide (cutting propagated). Native to high, dry areas of Turkey, this is sure to become a very popular addition to the Western xeric garden. The soft felted leaves are green on top and edged in white with the backs of the leaves also woolly white. The flowers are insignificant and should be sheared off to expose the evergreen, ornamental foliage. A vigorous grower, this plant does well in lean, well-drained soils, requiring little water once established. NOT RECOMMENDED for planting in regions with HOT, HUMID summer weather; the woolly foliage will "melt" from the humidity. A fine ground cover for under planting Caryopteris 'First Choice' (where it will accentuate the gray-green foliage) and blue or gray leafed grasses and perennials, to add contrasting texture and color.

Marrubium (Horehound) - a large group of flowering plants native to the Old World (North Africa, Europe and Asia). Some have showy flowers while others are grown for ornamental foliage. Resistant to browsing deer and rabbits.
Preferred growing conditions
Plant in a fast draining, infertile soil with full sun. In arid climates, it can be grown in dry clay. Mulch with gravel, pine needles or not at all.
Water regularly the first growing season to establish the plant. Thereafter, infrequent but deep watering is all this plant needs.
Deadheading recommended to prevent re-seeding and keep the ornamental foliage fresh and tidy looking after flowering is done.
Fertilize lightly in the fall with Yum Yum Mix.
Special comments
Cut back to green stems in early to mid-spring.
These are low care perennials that don't like rich soil or a lot of water; this makes the plants leggy, prone to flopping and can shorten their lifespan; grow hard and on the dry side.
