Back in 2004 Sally Allsup, Landscape Architect created our Xeriscape Garden. Armeria maritima, commonly called thrift or sea pink, is a compact, low-growing plant which forms a dense bottom mounded tuft of stiff, linear, grass-like, dark green leaves (to 4" tall 10 cm). It supports globes of bright pink flowers that rise on long stems. It is a popular garden flower and has been distributed worldwide as a rock garden and cut flower. It does well in gardens designed as xeriscapes or rock gardens and can grow in dry, sandy, saline conditions such as coastal cliffs, grassland and salt marshes, salted roadsides and inland on mountain rocks. It is a common sight in British salt marshes, where it flowers April to October.
Armeria maritima has a great copper-tolerance, and is able to grow in soils with copper concentrations of up to 6400 mg/kg. One mechanism proposed is that small amounts of copper are transported up (read RISE) the shoot of the plant, and is excreted from decaying leaves. Some of the physiology and metabolism of this species has been described, of particular note is how the metabolism of this species is altered with elevated atmospheric carbon dioxide concentrations.
