How tall does a red potato plant grow?

Question

I misplaced where I put it and I don't want to pull it up for a weed!

Answer 1

About 24 inches if healthy.

Answer 2

We just dug our potatoes this week and most plants were over 3 feet tall, some nearly 5 feet.  But, this time of year they have mostly drooped over, so it probably won't be that high off the ground.

It's time to harvest potatoes, so if you do pull it up, you'll likely pull at least a small potato out with the roots and you'll know to dig there for the rest.
