• Eryngium have thistle-like flowers, made up of tiny bright blue flowers packed together in a cluster, surrounded by a ruff of spiny bracts. They flower during the Summer months of July to August. The flowerheads last well when cut and can also be dried to be used in floral arrangements.


• This unique specimen still retains the stunning blue flower tones of Eryngium, with the spiky bracts being silvery blue at the base, turning gold at the tip but its foliage retains its golden sheen - like Neptunes crown.


• These plants grow well in a variety of soils from dry, clay, sandy to well draining and prefer to be growing in full sunlight. Eryngium copes well in exposed and sheltered areas of the garden making them ideal for planting coastal gardens, hence they are commonly known as Sea Holly.

Watering Water regularly after planting until the roots are established. Once settled in, the plant is relatively drought tolerant and usually only needs extra water during prolonged dry spells. Plants grown in containers will need more frequent watering than those growing in the ground.

Best Growing Conditions Grow in sun or partial shade in fertile, well-drained loam. Choose a position with good airflow and enough space for the plant to reach its mature size. Mulch after planting and keep the root zone free from prolonged waterlogging, particularly through winter.
