A. Pearly Everlasting; Moonshine - Anaphalis margaritacea
The dry, chaffy character of the involucres of the heads suggests the appropriate name of Everlasting. Clusters may be gathered and placed in a vase or other receptacle without water and kept for an indefinite period. They are sometimes subjected to various dyes but it is doubtful if this adds anything to their attractiveness. In florists' shops they are frequently seen dyed a brilliant red or blue.
