"a blossom, flower" (used in certain names of flowers), occurs in James 1:10,11; 1 Peter 1:24 (twice).
"past the bloom of youth" (from huper, "beyond," and akme, "the highest point of anything," the full bloom of a flower: Eng., "acme"), is used in 1 Corinthians 7:36 , "past the flower of her age;" Lightfoot prefers the rendering "of full age."
