Silverheels Horehound (Marrubium rotundifolium) looking pretty nestled against a red boulder in my xeric bed. This plant is in its third year and keeps spreading slowly contrasting beautifully with the red stone. I love the silvery edges on its soft and wooly leaves. It is native to south facing slopes in the dry mountains of Turkey where it gets extremely cold and windswept, so it’s a natural for the steppe climate of Colorado. It’s in full sun in poor gravelly soil here and thrives with very infrequent watering. A beautiful plant I don’t want to be without.
