Fun Facts
- 🌱 Antennaria dioica is dioecious, meaning plants are either male or female; females produce seed while males have showier flowers but no fertile seeds—'Merlin' is typically female.
- 🌱 The silvery hairs covering the foliage and stems serve as sun protection and help reduce water loss in its native mountain habitat.
- 🌱 The common name 'Cat's Foot' refers to the resemblance of the flower clusters to a cat's paw, and the plant self-seeds readily, sometimes surprising gardeners with new plants the following spring.
