Seedling/Establishment
2-3 weeksSmall rosettes of fuzzy gray-green leaves; plants develop roots and begin lateral growth
Keep soil lightly moist but not wet. Avoid overwatering which causes damping off. Provide bright light. Thin seedlings to prevent crowding.
Vegetative Growth
4-8 weeksFoliage rosettes expand rapidly with increasingly large, silvery-gray velvety leaves forming ground cover
Reduce watering as plant establishes. Do not fertilize (excess nitrogen causes lankiness and reduced foliage quality). Ensure excellent drainage. Mulch with gravel around base, not over crown.
Flowering
4-6 weeks (mid-late summer)Fuzzy purple-pink flower spikes (candles) emerge from foliage; some gardeners remove them to emphasize foliage
Deadhead spent flowers if you prefer to focus on leaf display. Reduce watering. Continue excellent drainage. Flowering uses plant energy; foliage-focused gardeners may cut flower spikes early.
Dormancy/Winter
3-4 monthsFoliage remains evergreen to semi-evergreen; growth slows or stops in cold zones; may retain silvery appearance under snow
Provide excellent drainage to prevent winter rot (most common failure point). Avoid winter moisture. No supplemental water needed in most climates. In zones 3-4, mulch lightly after ground freezes if drainage is questionable.

Common Pests
-
Prevention is key: ensure excellent drainage, avoid overwatering, use gravel mulch instead of organic mulch around crown, improve air circulation. Remove infected plants. Improve soil drainage with sand/perlite amendments.
-
Ensure good air circulation and avoid overhead watering. Remove affected foliage. In severe cases, apply fungicide. Usually only occurs with excessive moisture.
-
and
Hand-pick, especially at dusk. Use copper barriers or tape around affected areas. Beer traps. Encourage natural predators. Typically minor pest issue.
-
Spray with strong water stream to dislodge. Insecticidal soap for heavier infestations. Usually self-limiting outdoors.

Harvest Tips
Lamb's Ear Big Ears is primarily grown for ornamental foliage, not harvested like culinary herbs. Pinch off flower spikes at any time to redirect energy to foliage or remove them in late summer before cold. Can cut back dead or damaged foliage in spring. Divide established clumps every 3-4 years in spring for propagation.
Fun Facts
- 🌱 The 'Big Ears' cultivar was selected specifically for its oversized foliage compared to standard Lamb's Ear, sometimes producing leaves 3-4 inches long—noticeably larger and softer than the species.
- 🌱 Stachys byzantina is native to Iran and Turkey, earning it the common name 'Lamb's Ear' due to the uncanny resemblance of its leaves to a lamb's woolly ear—soft, gray, and touchable.
- 🌱 This plant is so drought-tolerant that in many climates (zones 8-9), it requires virtually zero supplemental water once established, making it an excellent choice for water-wise and xeriscaping gardens.
