from Stewart Robert Hinsley contains these words:

No idea which variety - I have one and use the 'grapes' for jelly - if I
remember to birdproof them in time.


You probably do mean Mahonia aquifolium then. I think of it as a
spring-flowering shrub, rather than a winter-flowering shrub. Mahonia x
intermedia flowers considerably earlier. (On the other hand, it's rather
on the big side, given the OP's criteria.)

My one is reaching for the light, and is about four feet high - but well
over six feet long...

Mahonia x intermedia can get to 8 or 10 feet tall - but, yes, Mahonia
aquifolium does have a tendency to spread.
