3-6 weeksPlants develop multiple stems with increasingly fine, lacy, silvery foliage; rapid height and spread increase
Pinch growing tips to promote bushiness. Water when top inch of soil is dry. Begin fertilizing biweekly with balanced fertilizer.
Established Foliage
4-8 weeks ongoingFull, dense mounded form with maximum silvery-gray, finely cut foliage; plant reaches mature size
Continue moderate watering and fertilizing. Prune as needed to maintain shape. Transition to outdoor hardening if grown indoors.
Flowering
6-12 weeks (summer through fall)Small, daisy-like yellow flowers appear at stem tips; flowers are secondary to foliage display

Fun Facts
- 🌱 Pewter Lace gets its common name from its resemblance to fine pewter lace fabric; the silvery appearance is due to fine hairs on the leaf surface that reflect light.
- 🌱 In warmer zones, Pewter Lace can be treated as a long-lived perennial and grown indoors as a houseplant for years, improving with maturity.
- 🌱 The plant is native to the Mediterranean and parts of Africa, and its silvery foliage is an adaptation to hot, sunny, drought-prone climates where reflective leaf surfaces help reduce water loss.
