Quote:"Flowers go riot " - okay?
Not okay. Use the word riot sparingly and carefully. You can talk about a riot of flowers, but it's rather unusual. Never "go riot". It's a noun, and used as a metaphor.
Your dictionary will be of help. Or a thesaurus?
I think he may have been thinking of 'run riot'. Things definitely can run riot. If people run riot, they behave in a way that is not controlled, running in all directions or being noisy or violent:
I dread them coming round because they let their kids run riot.
If your imagination runs riot, you have a lot of strange, exciting, or surprising thoughts:
My imagination was running riot, thinking of all the ways that I could spend the money.
I can definitely imagine flowers running riot in a garden in the spring.
