Cherry Question

I'm very confused.  I think these are all cherry trees, but they have flowers in the different months, Feb, March and April in my area. I can tell that they're not the same, but are they just different kinds of cherry, or one of them is not cherry?

This is the kind of cherry(?) I see in Feb. Is this cherry or something else? I know this one is not as pretty as the others. The flowers are smaller.

Here's the one from March. I'm 90% certain this is cherry, but it's different from April version.

And, this is the one in April. I'm pretty sure this is cherry. The April version has the biggest flowers.

Please help.

 

Thanks, Gale. Orange blossoms? I don't think I've seen it.


Does anybody know the answer to my question?
