Yukon Gold, Red Norland and Kennebec don't need tall towers for example...are commercially available and are closer to the base. Correction of Nathan's response RED OX grows close to the base a huge tower is just waste of dirt.
Most blue varieties around tend to grow longer stolons so it may be better to grow in a tower, at least on my experience.
Good luck
