Crandalberry? Mystery berry

A local rancher has given me two bushes that he says are crandalberry (sp)? An alleged cross between a high bush cranberry and something else?  He has been promising me a few bushes for a couple years and came through the other day. The berries are nickel size and blue. They are prolific producers, he removed these from near his back door because they carpet the sidewalk and track into his house. I'm curious if anyone has heard of this berry? I won't be able to narrow it down until it puts out some more leaves and blooms. It might be something else entirely than what he remembers being
told as a kid but maybe it is a thing.

Robert, I asked Mr. Google about "Crandalberry" which only produced something about a candle maker.

So I asked about "cross cranberry with blue colored berries" and found that there is a plant or two that has been crossed with a cranberry and a blueberry.

I am looking forward to reading about how these berries turn out.

highbush cranberry is a viburnum, and there are other viburnums with bluish berries, so it doesn’t sound super outlandish, but beyond that, i dunno. nothing i’ve ever heard of, and sounds potentially pretty cool. hope we can get a full report with pics when it’s in leaf/fruit?

another thought… ‘crandall’ is the only named cultivar i’ve heard of, of clove currant, Ribes odoratum, which does have largish ‘nickel-sized’ berries. i’ve never seen the berries described as blue. the fruit color varies in the species from kind of amber-colored to black. Crandall seems to ripen to black.

even with no leaves, it should be relatively easy to distinguish a ribes from a viburnum.

It's in bud right now so leaves should be coming out. I would say it doesn't have a ribe looking structure and when I asked if the berries had attached sepal tails he said they don't. I thought maybe elderberry, but nickel sized doesn't sound right.

i’m rootin’ for viburnum, then.

Given what the one person said about hybridized cranberry/ Blueberry, maybe you misheard & they said it was a cross of highbush Blueberry & cranberry?

Apparently, this bush has been shared with several of the older ranching families through the area. I'm really curious. Everything is just beginning to bud out so it won't be long for a look at  leaf.

It's probably a Crandall black currant: https://www.isons.com/shop/berry-plants/currant/crandall-black-currant/

Robert, have you ever had a chance to taste one?  I'm super curious what they are like.  I've never really investigated viburnums, but there seems to be a lot of promise and there seem to be a lot of hybrids that have been created for use as ornamentals.  Seems like at least a few of these hybrids could have nice flavored berries.
