I have found one that looks very weird. The petioles are up to
2-3 cm, and the leaves are very ovate (NOT obovate), and toothed.
I have B. vulgaris and B. thunbergii, but it doesn't match either,
unless the juvenile form of the former is very different from the
adult. Or it could be a natural hybrid.

Any guesses?

And how long do deciduous berberis take to flower from seed, because
that would identify it?
