My Verdal Longue ,5 year sold now,had a lots of fruits this past Summer but only a couple got ripe ,and ,very late in November,and did not accumulate the high sugar needed to have.
It is because our very hot August followed by very cold September,and October,with many cold rains.
I can estimate that it has a closed eye and dark red interior judging from the 2 ripe fruits I had.
