However, you could use "flower" as a near-homophone. While it's not spelled exactly the same and the pronunciation differs slightly, it's close enough that it could be used in a playful or poetic context.
For example:
* "I need to buy some flour to bake a cake."
* "I bought some flour to bake a cake, but I accidentally bought a bouquet of flowers."
