Betrayed by our Intuition

In the previous post, I presented an argument with two premises and asked if the conclusion in the third statement was logically valid. I repeat the argument here:

        1. Roses are flowers.
        2. Some flowers fade rapidly.
        3. Therefore, some roses fade rapidly.

Is that a valid logical argument?

Certainly we know from experience that some roses do fade rapidly. But that empirical fact does not matter here. We are concerned with the validity of the conclusion given the two premises.

As a matter of pure logic, the conclusion in (3) does not follow. Therefore the argument is invalid.
