A hops vine planted this spring will put most of it's energy into establishing roots and will likely grow to a slender 6-7 feet tall. You may get a handful of hops berries. This is what happened for us last year, our first year of growing hops.
This year, the vines are sprouting with vigor, sending at least a half dozen shoots out and already they are 3-4 feet long. Expecting the plants to be MUCH larger this season. Not sure what that will mean for a hops harvest but certainly more generous.
By next year, we expect the vines to be reaching mature heights and producing in a useful way. Until then, we're enjoying the robust nature of the plants and the shady covering over their lattice supports.
Not sure what variety you are considering, but we planted Cascade, Chinook and Crystal and all are growing at a similar pace. We bought organic rhizomes: https://www.leafari.com/hops.html
