Hi Alex, welcome to the Hosta Forum
Your zone should enable you to grow some great Hostas, like Rose said you will need some shady areas, hosta's also do best with an ample supply of water. I would recommend visiting some hosta sites to get an idea what the plants will look like and their sizes. Some of the ones I like are:
https://www.inthecountrygarden...
https://www.hostahosta.com
https://www.nhhostas.com
These sites will give you some good ideas, so that when you go to your local nursery's you will have a good idea what to look for.
