The term WHITE-LEAFED FLOWER can be solved by the five-letter word CALLA. CALLA is a genus of flowering plants in the family Araceae, native to moist temperate and cold regions of Europe, Asia, Africa, and North America. The genus consists of eight species of herbaceous perennial plants, growing from rhizomes or tuberous roots. They have large, showy flowers with white or yellow petals and a central spike of small flowers.
