What is a five letter word for large blossom?

Answer 1

It could be an aster. The arnica, the Alpine, Heartleaf, and Mountain varieties all look like a daisy with a yellow center and yellow petals.

If you meant "word for daisy, like bloom," in other words a word that can be applied to the specific flower daisy, there is really no other five-letter word besides "bloom" that is applicable. For a word with more than five letters, you could use "blossom."

Answer 2

Lotus is a five letter word for large blossom.
