is a good way to go if you want to peel it off later to transplant. They are perenial, meaning you can plant now to increase their root mass and the above ground plant will die back each year or should be cut back. Think of it like a tulip, they are planted once as a bulb and come back each year. I'd suggest probably putting them in a 25 gallon container if you can't water it all the time. It will need water. I'd also suggest you add a layer of mulch 4" thick or so to keep it moist for longer during the summer, pots need more water than in the ground.
