they're hardy, they live in the garden. No need for a greenhouse Eileen.
If it's absolutely freezing where you are , you could give them a bit of protection until the last frosts go if you wanted to give them a bit more TLC.
They need to be kept frost free while young so better off in the GH for now, particularly if the containers are relatively small. You should move them outside as soon as all danger of frost has passed. At the end of this year you should protect the crown with a mulch of a few inches of bark chips or similar after they die down if leaving outside next winter.
I bought some bare roots a few years ago from Hayloft, in the Autumn, potted up and kept in the greenhouse until they had plenty of growth on them, planted out following summer. Good mulch in the Autumn.
Although they are pretty hardy, and unlikely to be hit by very hard frost now, don't assume they will always be OK. I lost most of mine 3 or 4 years ago after a series of very cold days.
