Product Information
Full details
This seed packet of Eryngium giganteum 'Miss Willmott's Ghost', commonly known as Sea Holly, is ideal for gardeners seeking architectural interest and pollinator-friendly plants. Its key benefit is the striking, silver-green stems topped with spiky, ornate bracts that provide dramatic visual appeal in borders, gravel gardens, and for dried arrangements. A minor caveat is its biennial or short-lived perennial nature, though it tends to self-seed readily to maintain its presence.

FAQs
When is the best time to sow Miss Willmott's Ghost seeds?
Sow seeds indoors in early spring (March-April) or directly outdoors after the last frost, typically from late April to May. They need light to germinate, so sow on the surface.
What kind of soil does this plant need?
It requires very well-drained soil. Sandy, gravelly, or rocky conditions are ideal. Avoid heavy, wet soils.
How tall does Eryngium giganteum 'Miss Willmott's Ghost' grow?
When fully established, the plant typically reaches a height of up to 100cm (approx. 3.3 feet).
Does this plant attract wildlife?
Yes, its nectar-rich blooms are highly attractive to pollinating insects such as bees, butterflies, beetles, and moths.
Can I use these flowers for dried arrangements?
Absolutely. The tall stems and unique flower heads are excellent for creating long-lasting dried flower arrangements.
How often should I water my Sea Holly?
Once established, Sea Holly is quite drought-tolerant. Water moderately during dry spells, allowing the soil to dry out between waterings.
What is the difference between a biennial and a perennial?
A biennial plant completes its life cycle in two years, typically growing foliage in the first year and flowering/seeding in the second, then dying. A perennial plant lives for more than two years, often flowering repeatedly each year.
Troubleshooting
Seeds not germinating
Ensure seeds are sown on the surface of the compost, as they require light to germinate. Maintain consistent moisture and warmth (around 18-21°C / 65-70°F).
Plants wilting or yellowing
This is often due to poor drainage. Ensure the soil is well-drained and avoid overwatering. Relocate plants to a sunnier, drier spot if possible.
Leggy growth with few flowers
The plant may not be receiving enough sunlight. Move it to a sunnier location. Ensure adequate spacing to prevent overcrowding.
Pest or disease issues
Generally pest and disease resistant. If issues arise, ensure good air circulation and appropriate soil conditions. Avoid overly wet conditions which can encourage fungal problems.

Setup, Compatibility & Care
Sowing Seeds:
Sow seeds indoors in early spring or directly outdoors after the last frost. Seeds require light to germinate, so sow them on the surface of a well-drained seed compost. Keep the soil consistently moist but not waterlogged.
Transplanting:
Once seedlings are large enough to handle, transplant them into individual pots. Acclimatize them to outdoor conditions before planting them in their final position in late spring or early summer.
Soil Requirements:
Crucially, 'Miss Willmott's Ghost' requires well-drained soil. It thrives in sandy, gravelly, or rocky conditions. Avoid heavy clay soils or areas prone to waterlogging, as this can lead to root rot.
Sunlight:
Plant in a location that receives full sun for the best growth and flowering. Partial shade may be tolerated but can result in less vigorous plants.
Watering:
Once established, the plant is relatively drought-tolerant. Water moderately during dry spells, ensuring the soil has a chance to dry out between waterings.
Care:
Deadhead spent flowers to prevent excessive self-seeding if desired, or leave them to develop seed for the birds and to encourage natural propagation. Cut back dead stems in late winter or early spring before new growth appears.
Compatibility:
Excellent companion for drought-tolerant perennials, ornamental grasses, and plants that prefer gritty conditions. Suitable for cottage gardens, gravel gardens, coastal gardens, and wildlife gardens.
