Growth Stages

1

Establishment

4-8 weeks

Young plants from nursery containers settling into garden bed with initial root development

Water regularly to keep soil consistently moist. Mulch around plants to retain moisture and suppress weeds. Fertilize lightly with balanced fertilizer.

2

Vegetative Growth

Several months

Vigorous spreading growth with increasing silvery foliage coverage, runners extending across the soil

Continue consistent watering. Pinch back stems occasionally to encourage fuller, bushier growth. Remove any solid-green reversion shoots immediately to maintain variegation.

3

Flowering

4-6 weeks (spring to early summer)

Bright yellow tubular flowers appear in late spring to early summer, held above the foliage on short spikes

Flowers are not essential to plant health. Deadheading extends bloom but is optional. Continue normal watering and care.

4

Maturation & Spread

Ongoing (12-24 months to full coverage)

Plant fills in designated area as a dense, attractive groundcover with established runner network

Minimal care required once established. Monitor and contain if needed; this cultivar is less invasive than the species. Divide if needed for propagation.
