yea, you could move them, but it's going to be a lot of work if it's in the ground. I would dig it up and stick it in a 5 gal. bucket with a lot of holes cut in the bottom with about 2 inches of decent sized rocks for a base to ensure drainage before you put the soil and the plant back in. That way when you find another spot, you can dig a hole (which you were going to have to do anyway) big enough to make top of the bucket flush or close to flush with the ground. If you have to move it again, you can just pull up the bucket, and you're on your way.
