With the exception of a cultivar 'Top Hat' that is often referred to as a dwarf, what you are looking for are those blueberries labeled "half-highbush". I can't tell you where to find them in your area but I can provide some cultivar names to look for. These are all quite cold hardy blueberries and small enough in size to be able to grow easily in a container. Most will stay 3' or less. In addition to 'Top Hat', look for 'Northsky', Northland' or 'Northblue'. 'Chippewa' may work too, but will get slightly larger.

If you were in a warmer zone, I'd also suggest 'Sunshine Blue' which is a mostly evergreen dwarf ideally suited to container growing. But it is form of Southern highbush and not as winter hardy as the others, especially in a container situation.

I bought a tophat blueberry almost 2 years ago, I got it from Jung Seed, it was shipped potted and so far it's doing okay, but it hasn't borne any fruit yet. I kept it outside all winter last year in a terra cotta pot, didn't seem to faze it, but the coldest it got last winter was barely below zero. The size of the blueberry wasn't very tall though, if memory serves correctly it was like maybe 5 inches high. At least it was potted though! I never buy from Gurney's anymore, although their fruit trees are usually pretty good. HTH! :)

We grow blueberries in 20-inch and 24-inch diameter plastic containers -- five plus years now. The containers are out 7x24. The soil mix is two to one peat to compost/manure with five to eight cups of perlite. We maintain two plus inches of pine bark mulch. Plastic netting protects the berries from the birds & squirrels. The bushes are Patriot and another from Pinetree. Both grow about five feet tall in the containers. Check with the grower for your zone. Good luck.

I HAVE FOUND GREAT SUCCESS BUYING RASBERRIES,BACKBERRIES, BLUEBERRIES (HALF-HIGHBUSH) FROM EBAY. THE DIFFERENT VARIETY OF PLANTS ARE AMAZING AND THE FEW SITES I HAVE ORDERED FROM ARE VERY KNOWLEDGABLE AND ARE USUALLY FAMILY OWNED NURSURIES. I AM VERY NEW AT GROWING IN CONTAINERS AND EVEN NEWER AT USING A COMPUTER SO YOU'LL HAVE TO FORGIVE ME FOR ANY MISTAKES I MAKE IN MY MESSAGES. TRY PLANTRANCH ON EBAY. HIS PRICES ARE VERY RESONABLE AND I ORDERED 3 BLUEBERRY PLANTS NEVER RECIEVED THEM, EVEN THOUGH HE HAD A SHIPPING CONFORMATION HE STILL SENT ME 3 MORE OUT WITHOUT ANY PROBLEMS. EVERYTHING I'VE GOTTEN WERE 10 TIMES BIGGER AND BETTER THAN THE DWARF CITRUS THAT I PURCHASED AT GURNEYS (THIS SPRING THEY ARE SENDING ME 2 REPLACEMENT PLANTS BECAUSE THEY DIDN'T SURVIVE A YEAR). TRY IT, I WAS A LITTLE SKEPTICAL UNTIL A FRIEND LET ME IN ON WHERE SHE GOT ALL HER EXOTIC AND HARD TO FIND PLANTS AND THEY ARE HEALTHY AND BEAUTIFUL.

Jeff, I've purchased blueberries from Jung's and have been quit happy with the size and quality.

Paulallen,
Are those self-watering containers you grow your blueberries in?
