I suspect soil and sunlight may have something to do with it. Also, are they the same age? I'm no expert, just that my Chinook look exactly like that.
You may be right on the soil and aspect. I may harvest some material this spring and plant it elsewhere to confirm that the habit is the same irregardless of where it is grown.
But I would call or email and get approval first. They maintain an enormous bank of clean plant stock and might not be thrilled to open a package with cuttings that might bring disease into their labs/grow areas.
For sure. I am sure they would not appreciate unsolicited or announced packages!

I am convinced this plant may be part native, but not totally...so they may not be interested in such a polluted specimen.

I am normally not overly impressed with single hopped ales, but this one is quite nice. Cheers.
