Here's the source of your "violets" reference:

"April Showers"

"Though April showers
May come your way,
They bring the flowers
That bloom in May;
And if it's raining,
Have no regrets;
Because, it isn't raining rain, you know,
It's raining violets".

[hoosiermama]

I know the song. But the line was used in book or movie too
