They root very easy. I took many a cutting and just put them in water with great success.
I heard many people don't like to root in just water. Some say the roots aren't strong enough. I have a lot of success with water rooting. Sometimes I put sphagnum moss in the water jar it gives the roots a good start for the transfer to dirt. Just don't put more than one cutting per container or you may never get them back apart.
