ARMERIA

(from Flos Armeriæ, Latin name for the flowers of a species of Pink). Thrift; Sea Pink. O RD. Plumbagineæ. A very interesting and pretty group of hardy alpine tufted perennials. Flowers pedicellate, collected in dense solitary heads; involucre scarious, sheathing the scape and turned downwards; petals cohering at the base, persistent; flower scapes leafle . Leaves linear, radical. As the majority of the species differ in mere technical details, we have given a representative group only. They are easily cultivated in a sandy loam and leaf soil, and are increased by seeds and division, separate pieces being planted as cuttings under hand gla es; or the rarer kinds should be potted and placed in a frame. The seed should be sown in spring, in pots of sandy soil, and placed in a cold frame. Although best grown as rock plants, most of them do well in pots and borders. A. vulgar is makes one of the best of edging plants.
