How many flowers do I have if all of them are roses except two, all of them are tulips except two, and all of them are daisies except two?

re(4): Already not the latest... another solution by Jim C)
Actually, from what I remember from structured logic, all and none are not diametrically opposed. As an example, if I have no elephants (which is quite correct by the way), then it is correct for me to say that "all my elephants are sleeping". It would not, however, be correct to say that "some of my elephants are sleeping", as "some" requires at least one.
