Thrift (plant): Armeria is a genus of flowering plants. These plants are sometimes known as "lady's cushion", "thrift", or "sea pink" (the latter because as they are often found on coastlines). The genus counts over a hundred species, mostly native to the Mediterranean, although Armeria maritima is an exception, being distributed along the coasts of the Northern Hemisphere, including Ireland, parts of the United Kingdom such as Cornwall, and the Pembrokeshire Coast National Park in Wales.
