Birch Cuttings

I heared that birch throws out roots as readily as willows. I am putting this to the test. I have taken three birch cuttings larger then two inches. How will they do?
If a willow cutting was taken - and I have heared that one can use up to a six inch piece of wood - and left in a bucket of water, then that cutting will throw roots and survive.
I have treated my birch with cutting hormones and planted them. We shall see.
Oh- I think this will work because both birch and willow are swamp trees, which means that they have a more favorable symbiosis with water then most trees. These trees thrive in wet, wet conditions that would rot out or kill another tree. Hence I think that having no roots (due to water rot) is not uncommon in these trees, and they expect a life of throwing out fresh roots simply for survival. Red alder and swamp cypress are other swamp trees.
