Description
Marrubinum supinum | Scallop-shell Horehound
Scallop-shell Horehound, also known as Spanish Horehund and Dwarf Horehound, is a perennial evergreen herb in the mint family native to Europe and western Asia. It bears whorls of tubular lavender flowers that bloom during the second year, and soft, velvety, sage-green leaves with white-edging that grows in a mounding, spreading habit. The young shoots and foliage are densely covered with white hairs.
It is often found growing in open woods, thickets, and along roadsides. Great for dry gardens and desolate sites as it requires NO summer water. Well-drained soil ensures Marrubinum supinums long-term prosperity. It has survived three winters down to 7 F in an open and exposed rocky planting site on our land.
Attracts lots of interesting insects.
