Zabel Sea Holly 'Neptune's Gold', Sea Holly 'Neptune's Gold'


Eryngium x zabelii 'Neptune's Gold' (Sea Holly) is an upright, herbaceous perennial with its multitude of intense, iridescent electric blue flowers, tightly packed into egg-shaped heads, that light up the garden in mid to late summer. They contrast against the spiny, bright golden foliage and flower bracts. The leaves emerge bright yellow, fade to chartreuse and then age to a nice gold and green combination. The long lasting, electric blue flowers are surrounded by bracts that are graduated from silver to gold and then soft lavender. A pretty color combination for borders, containers, foundations, mass plantings

  • Grows in clumps of stiffly erect, branched stems up to 20-24 inch. tall (50-60 cm) and 10-12 in. wide (25-30 cm).
  • Performs best in full sun in dry, sandy, well-drained soils. The sunnier the site, the more intense the blue! Tolerates poor soils. Avoid planting this plant in moist and fertile soils, where it will tend to sprawl and may require support. Drought and salt tolerant and deer resistant!
  • Excellent choice for sun baked, informal beds and borders or naturalistic plantings, where the steel blue flowers and foliage will superbly complement the vibrantly colored summer flowers. Ideal for small gardens. May be planted as a single specimen or in groupings. Perfect for cut or dried flower arrangements too!
  • Deadhead to preserve a neat appearance. Cut back in late summer after flowering is over.
  • Self-seeding may happen under satisfactory growing conditions, but rarely becomes a nuisance.
  • Transplants poorly and is best left undisturbed once established.
