Harvest Tips
Lambbrook Silver is grown as an ornamental foliage plant rather than for harvest. Stems can be cut for fresh or dried flower arrangements at any time during growing season. For dried arrangements, cut stems in morning after dew dries, hang upside-down in warm, dry location with good air circulation for 2-3 weeks.
Fun Facts
- 🌱 Lambbrook Silver's silvery coloration comes from fine hairs on the leaf surface called trichomes, which reduce water loss and reflect sunlight—an adaptation to hot, dry climates.
- 🌱 The plant's common name 'mugwort' may derive from its historical use as a bitter additive to beer (a 'mug') before hops became standard.
- 🌱 Artemisia ludoviciana is native to western North America and was used by Native American tribes for ceremonial smudging and traditional medicine.
