Blueberry Companion Plants in Clay Acidic Soil

Looking for advice for possible companion plants for a blueberry Shrub. I'm a student in the University of exeter in the Uk and I've been given a small area in my where I can add additional plants to where a blueberry shrub is in.
As, i'm from Devon, the soil type is Clay, and the the soil is very acidic which is good for the plant. I was hoping to use permaculture ideas to be able to grow plants around/beside the blueberry shrub that would help the overall area.
In terms of possibly attracting bees to help with pollination for the plant, etc... Any advice of help with regards to my situation would be very much appreciated.

Thanks.

I strongly suggest perusing Dr. Redhawk's Epic Soil series. There's a wealth of information there that will help you.

As to specific suggestions, calcium deficiency is often a cause of impermeability in clay soils. You might want to add a bunch of gypsum, which will add calcium without changing the pH.

Here in Ontario, blueberries and raspberries are some of the first food-bearing succession plants after a fire event or clearcut, or even when a tree drops in the boreal and opens up a patch of light. You might want to see what else grows in the wild with blueberries, and then see what you can do about assembling a guild that spans all trophic levels.

Good thoughts, though. There are many knowledgeable people on this site that will be able to help you, and some from much closer to where you're located. Keep us posted, and good luck.
