Outside, in full sun. You can put them in the ground or in a pot, but you'll have to do something to keep it protected over the winter. In your zone, if you put it in the ground, you'll have to do some kind of winter protection (coving with soil or mulch or wrapping with burlap). If you keep it in a pot, bring the pot into an unheated garage or basement for the winter, keeping the soil moist, but away from light and heat.

According to helpmefindroses.com, you can use these as borders, in rosebeds or keep them in pots.

I have some in pots and some in the ground. They do well either way as long as they're OUTSIDE!

I just rec'd a kordana rose plant as a gift. I live in zone 6. I am looking to move in the next couple months and dont know what to do. should i plant the plant outside and then dig it up in a couple months or just keep it as is until I move?
Also is it safe to plant outdoors in zone 6?

I would move it into a bigger pot to give the roots room to grow. Next spring you can plant it outdoors. As we keep saying, roses are outdoor plants. They will do quite well in zone 6 if given adequate sunshine, water and care.

I bought Kordana roses from CVS when they were selling them for Easter. Keep them in they kitchen and was watering them at the most once a week think I could plant them outside when the weather turned warmer. None of them died and around late april I planted them in a garden I had cleared useing QuickStart and soil with peet mulch, no fertiilizer and mulch. Now I find them growing much bigger and spreading out, so I thought maybe them needed something to grow up not out. I looked online and found out them are supposed to be kept in a pot. Now how do I kept the roses growing and survive the winter in the ground? Or can I?

The info stick which came with mine indicates that it is hardy for zones 5-9, so zone 4 may get too harsh of a winter for them to withstand being planted in the ground, outside, even if protected.
