Here in Germany you can get them easily. Cuttings root readily. They are pretty invasive in a bog. Spread everywhere and build mats.
Nice flower, and lots of fruits on mine.
I never tried to sow them.
Maybe you can grow them from seed out of the dried ones, but I found sometimes also fresh ones in the supermarket here.
I have a very similar photo from this year! The ones in mine are Vaccinium macrocarpon. Much bigger than the more common Vaccinium oxycoccos we usually find. V.macrocarpon is the species most common in cultivation and is not thought to be native to B.C.
These were found in a small bog on one of the smaller Gulf Islands. It's a mystery as to how they ended up there. Was it from a deliberate human introduction or could it possibly have been dispersed by a bird that fed on cultivated cranberries somewhere?
