Eryngium maritimum

Eryngium maritimum, commonly known as Sea Holly, is a species of flowering plant in the family Apiaceae. It is native to most European coastlines and is known for its distinctive spiky, silver-blue foliage and cone-like flower heads.

Description[edit | edit source]

Eryngium maritimum is a perennial plant that typically grows to a height of 20–60 cm. The leaves are stiff with a sharp point, and are bluish-green in color. The flowers are small and thistle-like, arranged in a dense, cone-shaped head that is surrounded by spiky bracts. The plant blooms from July to September.

Habitat and Distribution[edit | edit source]

The Sea Holly is predominantly found in coastal areas, particularly on sandy beaches. It is well adapted to these harsh environments, with its deep root system allowing it to withstand strong winds and its thick, waxy leaves helping to prevent water loss. The plant's range extends from the Atlantic coast of Europe, including the British Isles, to the Mediterranean and Black Sea.

Cultivation and Uses[edit | edit source]

Eryngium maritimum is often grown as an ornamental plant due to its striking appearance and its ability to thrive in poor, sandy soils. It is also used in traditional medicine, particularly in the treatment of urinary tract disorders.

Conservation[edit | edit source]

While not currently considered endangered, the Sea Holly's habitat is under threat from coastal development and sea level rise. Conservation efforts are focused on preserving its natural habitat and promoting its cultivation in gardens.
