LIMONIUM SEA-LAVENDER, MARSH-ROSEMARY
(Annual) perennial herb, scapose; rhizome ± woody. Leaf: few to many; basal generally in rosette, oblanceolate to obovate, entire or lobed, generally petioled; cauline generally small, scale-like. Inflorescence: panicle, branched ± at plant base, flowers in sessile, 1–3(5) flowered spike-like clusters, each 3-bracted at base, clusters evenly spaced along branches to crowded at branch tips. Flower: calyx funnel-shaped, base tubular, lobes generally fused, generally 5–10-ribbed, generally pink to blue; petals free, white to yellow or pale violet; styles 5, ± free.
± 300 species: ± worldwide, generally in saline soils. (Greek: meadow, from habitat of many species) [Karis 2004 Biol J Linn Soc 144:461–482] Many cultivated species; those of Mediterranean origin potentially could escape and naturalize. Limonium arborescens Kuntze, illeg. may have been misappl. to the waif Limonium brassicifolium (Webb & Berthel.) Kuntze.
