chrysanthemum (n.)

composite plant native to Europe, Asia, and North Africa, the national flower of Japan, 1550s, from Latin chrysanthemum, from Greek khrysanthemon "marigold," literally "golden flower," from khrysos "gold" (see chryso-) + anthemon "a flower," from PIE *andh- "bloom" (see anther). "The generic name is now rarely appropriate, as only a small number have yellow flowers" [Century Dictionary].
