(Silver Horehound) Wooly white hairs on the underside of gray-green foliage help conserve moisture and give this drought resistant groundcover a silvery appearance. This explains the plant’s common name as well as the second word in its botanical name, incanum, which means “hoary” (whitish-gray) in Latin.

The downward curving leaves of Marrubium incanum have a pleasant, suede-like texture and attractively scalloped and toothed margins. During summer, they are topped by fragrant whorls of tiny, pale lilac flowers that fade to white. Similar to so many nectar-rich plants in the mint family, it is a favorite among bees.

This Mediterranean native tolerates cold and heat as well as dry spells. In the wild of its homelands, including Italy, it appears in grassy areas beside agricultural fields along with wildflowers like Red Poppy. Various types of Marrubium have a long history of medicinal use, but this one is primarily valued as a pollinator plant and resilient, ornamental perennial.

For best growth, give Silver Horehound full sun, well-drained soil, and average watering based on local precipitation.
