Snapshot: This Mediterranean native with a funny name is a lovely addition to dry gardens. A low-growing perennial, horehound features attractive, fuzzy, silver-green foliage that demands to be touched. In summer, it produces foot-tall spikes of lavender flowers. Horehound makes a lovely border, perfect for along paths and at the front of plantings where you can appreciate the soft leaves.
