Do all pine trees have cones?

I went out to take a picture of the different pinecones of my two trees in the front.

This is the pine cones from the Scotch pine which Dad doesn't like to

pick up in the spring after a wind storm.

Then I went to get a picture of the pine cones on the White Pine,

Idaho's state tree by the way, and guess what?  No pinecones.

I never knew that before.  We are not supposed to be able to grow

this pine tree in this cold of a climate, but has been doing well for many years.

Guess we give it lots of love.
