Sea Holly ‘Oxford Blue’ has amazing blooms on upright stems. The rounded, purple blue flower heads are surrounded by elaborate, spiny, metallic blue bracts that last an age.

The evergreen foliage grows to forms clumps of deeply divided leaves in shades of silver and green. Their spiky form is excellent for adding texture to the garden and they are quite long lived.

Sea Holly ‘Oxford Blue’ holds the prestigious RHS Award of Garden Merit, so you know it has been put through its paces.

Sea Holly are a perfect complement to a cottage border, and as they establish you will get to enjoy more and more flowers. If you dead head the spent flowers throughout the season, you can increase bloom time – we have had it in flower from November to May.

Plant Sea Holly ‘Oxford Blue’ in a sunny spot to get the best colouring. Sea Holly grows best in moderately fertile to humus rich, well drained soil. Though, in saying this, they are quite adaptable as they are endemic to poor, dry and rocky soils. Good drainage is the most important element and they can thrive in hot, dry sites once established.

Sea Holly is a member of the parsley family, Apiaceae.
