Sea Holly 'Tetra Petra' has dense, compact growth with sharp, blue bracts and flowers. Perfect for adding some stunning colours and shapes to the garden. The colour is really quite astounding.
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 these plants can be quite long lived.
You can choose to leave the flower stems standing through winter, they can remain ornamental and the birds can enjoy them. Simply cut them back early spring to make way for the new growth.
Sea Holly are the perfect complement to a cottage border and as they establish you will get to enjoy more and more of their fabulous flowers. If you dead head the spent flowers throughout the season, you can increase bloom time and enjoy more florets – we have had it in flower from November to May. Blooms suitable for picking and drying.

Plant Sea Holly ‘Tetra Petra’ 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. Give them a bit of space to do their thing, I’ve had mine crowded out by various grasses and perennials over the years, so am looking forward to re-establishing a space for them. Tolerant of coastal conditions.

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