It's a bit hard to tell the variety of a blueberry from a photo - there are so many different varieties being sold now. Yours look fine though. I dug pits for mine and filled them with muck and ericaceous compost, and planted in those, which is similar to sinking a large pot in the soil really. As long as you start them off in ericaceous compost and when you mulch use well rotted manure or other acidic manure, and never use lime or spent mushroom compost you should be ok. They do like a moist soil as do the blackcurrants.
