Growth Stages

Seedling

2-3 weeks

Tiny seedlings emerge with pale green linear leaves

Keep soil lightly moist but not waterlogged. Provide bright light. Thin seedlings to proper spacing.

Vegetative Growth

6-8 weeks

Plant develops characteristic silvery-gray, finely textured foliage. Bushy form develops.

Water sparingly. Pinch back growing tips to encourage bushiness. Full sun exposure deepens silver coloring.

Pre-Flowering

2-3 weeks

Plant reaches mature size with dense, cushion-like form. Flower buds begin forming at stem tips.

Reduce watering further. Ensure excellent drainage. No nitrogen-heavy fertilizing.

Flowering

6-10 weeks (mid-summer through early fall)

Bright yellow, button-shaped flower heads appear in clusters above silver foliage. Flowers are daisy-like in appearance.

Deadhead spent flowers to encourage continued blooming. Minimal watering required. Plant is most aromatic now.

Post-Flowering & Dormancy

4-6 months

Flowering subsides in cooler months. Foliage remains evergreen and decorative.

Prune back in spring to maintain compact shape. Minimal watering. Ensure good air circulation to prevent fungal issues.
