The sea hollys are sun loving perennial plants with striking foliage. Big Blue has teazle-like flowers with spiky bracts, both of which are bluish in colour. Flowers are borne towards the end of summer.

Leaves are either silver-blue, as are the upper stems giving a rather striking look. Use them in a border to add a change of texture with their 'hard', spiny look.

Eryngiums will grow in most soils, as long as they are well draining. They do require a sunny site, but are good in exposed situations.
