As members of the Plumbaginaceae family, they are perennials, leaves are basal, narrowed to base, simple in shape without stipules. Flowers are in branched cymes (in the lavenders case). The calyx is fused proximally with free scarious lobes distally. Petals 5, stamens 5, ovaries 1 celled (Stace 2010).

This is one of many Sea-lavender species growing at Blakeney Point. It is also one with many similar sub species but the following description is purely for Rock Sea-lavender, Limonium binervosum agg.

Stems are relatively tall, and the whole plant grows up to 50(70cm) according to Stace (2010) though the picture here shows a much shorter specimen:

This species is well branched from low down, (often with many sterile branches below). Leaves  are 7-22mm wide (Stace 2010), obovate shaped with 3 veins but no pinnate leaf veins. Note the spine on the tip of the leaves (Rose 2006).

Inflorescence spikes  are 13-25mm and rather lax with 2-5 spikelets in lowest cm. The outer bracts 2.1-3mm and inner bracts are 4-5.3mm (Stace 2010).
