Honeyberry is considered a cold tolerant plant.
The article below gives you good growing information.

I would check with your Agriculture Dept. for varieties that may be available in your region.

In container, and especially in grow bags, I would recommend that they get some shade. The full sun may be too much since water will leave the container much faster than in ground. In fact, you may even want to water more during these times. I do recommend having fertilizer handy, as they will use these very quickly in container.

Your extension agent should be able to tell you if they are grown in Maine.

To get berries, you need a pollinator of a different cultivar. You can't buy two of the same variety, in other words.

Your blueberries won't cross pollinate because they are in a different species. Plants must be of the same species to cross pollinate.
