There's one issue, even if we throw away plural "фиалки": круглеет should be круглеют if applied to multiple nouns.
You may be confused with the first line, which may make you feel like something is missed there: Золото в потолке зодиаком (do what?)
I'm not a philologist to explain it correctly, but it's kind of poetic device, methinks. Or something.
