Lamb’s Ear Seeds – Stachys byzantina | Big Ears ‘Countess Helen von Stein’ | Silver Velvet Ground Cover

Lamb’s Ear (Stachys byzantina) is one of the most distinctive and tactilely irresistible perennials in the garden — a spreading ground cover whose densely felted, silver-gray leaves are so thickly coated in soft white hairs they feel like velvet. A member of the Mint family, this drought-tolerant, deer-resistant perennial forms a low, spreading mat that looks fresh and architectural throughout the season. The ‘Big Ears’ cultivar (also known as ‘Countess Helen von Stein’) produces leaves up to 12 inches long — twice the size of the common type — for a bolder, more dramatic garden presence. Open-pollinated perennial.

Planting Guide

• Indoor start: Sow seeds 8–10 weeks before last frost in starter trays with quality starter mix. Do not cover seed — press gently onto the surface and maintain moisture; light is required for germination.
• Germination temperature: 70°F; germination in 21–35 days.
• Transplanting: Move seedlings outdoors in spring. At transplanting, pinch back to encourage compact, bushy growth.
• Spacing: 16 inches apart.
• Soil: Prefers well-drained soil — Lamb’s Ear does not tolerate waterlogged conditions, especially in winter. In heavy clay soils, improve drainage before planting.
• Sun: Full sun for best foliage density; tolerates partial shade though growth may be looser.
• Maintenance: Remove spent flower spikes and tattered leaves in early spring. Divide clumps every 3–4 years to maintain vigor. A reliable self-seeder and root spreader — ideal for naturalizing a large area.
