One term that seems maybe suitable is overripe, but this seems to be
specific to fruits which when overripe exhibit different changes
compared to those of vegetables: overripe fruit destructure and
decompose, but the vegetables that I’m looking for an adjective for
often become tougher, woody perhaps, more difficult to chew, etc.
So it’s not so much that they’re overripe because these qualities may
essentially prevent it from even properly ripening.
I also like overgrown, but that usually describes vegetation that
has grown out of control, so overloading the meaning of this word seems
problematic due to the overlapping context.
An adjective I usually do see used for this is old, but that doesn’t
seem to really capture the concept specifically enough.
Maybe late harvest or past due? These compounds do the job to
describe it but seem not straightforward to use in a sentence like
adjectives are normally used.
