Fun Facts
- 🌱 Dwarf cotton lavender is not actually a lavender at all—it belongs to the Asteraceae (daisy) family, while true lavenders are in the Lamiaceae family. The name derives from its silvery foliage resembling cotton and its historical use in similar garden contexts as lavender.
- 🌱 The plant has been cultivated for centuries in Mediterranean gardens and was traditionally used as an insect repellent, with dried plants placed in wardrobes to protect clothing from moths and other pests.
- 🌱 Its finely divided, feathery foliage contains aromatic oils that give it a distinctive camphor-like scent when brushed or handled, which some gardeners find pleasant while others find it pungent.
