Celosia spicata Named for Socrates’ ill-tempered wife, Xantippe, known for her cold and shrewd demeanor, this celosia bears icy silver petals, an unusual metallic color not frequently seen in the garden. Its upright, 24-inch form produces erect flower heads in pink hues that fade to silver. Heat-tolerant and striking in both landscapes and containers, it brings a touch of elegance and drama to cut or dried flower displays. Approximately 300 seeds per gram. Germination code: (1) and (6)
