Eryngium giganteum 'Silver Ghost' is a striking perennial known for its silvery-blue foliage and unique, spiky blooms that add a dramatic touch to any garden.

 

The name Eryngium comes from the Greek word eryngion, meaning "thistle," referencing the plant's thorny appearance. The species name giganteum highlights the plant's large, robust nature. Silver Ghost is a particularly ornamental variety, with its silvery stems and bracts surrounding its tiny blue flowers, creating a frosty, ghostly effect that makes it a standout in borders and flower beds.

 

This hardy plant thrives in well-drained, moderately fertile soil and prefers full sun. Eryngium Silver Ghost grows to a height of 75 - 90 cm, making it perfect for the middle or back of borders, coastal gardens, or as part of a wildlife-friendly planting scheme.

 

Its architectural shape and long-lasting blooms attract pollinators, such as bees and butterflies, while adding texture and structure to the garden.

Sowing Instructions

 

Indoors: Sow seeds in trays or pots filled with moist, well-drained compost from January to March. Lightly cover the seeds with compost and keep at 18-21°C. Once seedlings are large enough to handle, transplant them into individual pots and harden off before planting outdoors after the last frost.

 

Outdoors: Sow directly into prepared, weed-free soil from April to May. Lightly cover the seeds with soil and keep moist until germination occurs. Thin seedlings to the recommended spacing for healthy growth.

 

Eryngium Silver Ghost is perfect for adding a touch of elegance, texture, and striking colour to your garden. Its unique appearance, long-lasting blooms, and ability to attract pollinators make it ideal for creating focal points, dramatic borders, or cutting gardens.
