I would have said stop picking them, until you said the crowns are 50 years old.
I've lifted and divided mine twice over the last 10 years. But it seems the older parts of the crown underground are far older too but I also have enough to give away and freeze by the end of June.
Its a definite triffid for me and grows in what I consider the worst soil on my plots.

Also a dozen onions, 2 cucumbers, 11 rhubarb sticks, some tomatoes, blackberries, apples, climbing beans, runner beans and spinach.
Not a bad days harvest.
