That example works only because it is a list of complete sentences. The "and" at the end makes the list grammatical. If it said "Roses are red, violets are blue, sugar is sweet, so are you", it would not be correct. Between any two independent clauses (complete sentences), you need a semicolon, a period, or a conjunction. In this sentence, only a comma is used. Either a semicolon or a conjunction (such as "and") is necessary.
Indeed, this is where Ukrainian is different from English. Comma splices are perfectly correct in Ukrainian.
