花(はな、カ)

Meaning: flower

Components: 艹(grass), 化 (change)

My hack: A flower is a kind of plant, so we have to have 艹, and flowers change more quickly than any other plants (i.e. the blooms die).

OR

the 化 part could be a person on the left, and another person on the right on his/her knees holding a bouquet of flowers behind his/her back.
