Dutch Pimp,( I cut and paste.)
The one that did grow columar was "Medicine man," the same breeding as GWR,but by a different person.
I only had the one plant of it,so I dont know that all do grow that way.
But I would speculate that the GWS would be more apt to be columar then the Widow.
I have grown both,but thats my guess.
Peace,
