On coastal cliffs, rocks and dense shingle, Rock Sea-lavender braves the onshore sea-winds, showing a great display of design and colour from July to September. Appearing to have stems which zig-zag, this plant is well-branched from low down as well as further up. It bears small clusters of lilac-coloured flowers (6 – 7 mm) in spikes which hold the flowers in an upturned position on erect, stiff stems. The narrow, evergreen, spoon-shaped leaves have one to three veins. A perennial which reaches about 30 cm high, Rock Sea-lavender is a native species and it belongs to the Plumbaginaceae family.
I first recorded and photographed this plant in 2009 on the cliffs around Killiiney Bay, Co Dublin.
