Eryngium ‘Big Blue’ – A Bold Architectural Statement

Eryngium ‘Big Blue’, commonly known as Sea Holly, is a striking perennial that brings dramatic structure, intense blue hues, and pollinator-friendly blooms to the garden. With its steely blue, cone-shaped flowers surrounded by spiky, silvery bracts, this eye-catching plant is perfect for adding texture and contrast to sunny borders, gravel gardens, and coastal landscapes.

Why Grow Eryngium ‘Big Blue’?

Vibrant, Electric Blue Flowers – Deep blue, thistle-like blooms stand out brilliantly, intensifying in colour as they mature.

Architectural & Textured Foliage – Glossy, spiny green leaves form a compact, upright clump, providing year-round interest.

Thrives in Full Sun – Ideal for dry, well-drained areas, making it perfect for Mediterranean-style gardens, wildlife-friendly spaces, and gravel borders.

Loved by Pollinators – A magnet for bees and butterflies, supporting biodiversity in your garden.

Drought-Tolerant & Hardy – Fully hardy in the UK, once established it requires little watering and thrives in poor, dry soils.

Planting & Care Guide

Position: Prefers full sun, ideally in an open, airy position.

Soil: Best in well-drained, sandy, or rocky soil—avoid overly rich or heavy clay soils.

Watering: Drought-tolerant once established; only requires occasional watering in prolonged dry spells.

Maintenance:

  • Leave flower heads for winter interest and to attract wildlife.
  • Cut back faded stems in early spring to encourage fresh growth.
  • Avoid excessive fertilization, as it can lead to weak, floppy growth.

Perfect Plant Combinations

Eryngium ‘Big Blue’ pairs beautifully with grasses, lavender, echinacea, and rudbeckia, creating a naturalistic, wildflower meadow effect. It also makes an excellent dried flower, holding its stunning colour long after cutting.
