I found four itty bitty potatoes. When I pulled up the plants, there were no long reach stems / root systems like the videos I saw on U Tube. I don't know if the 10 inches of rain from the recent tropical storm caused a rot issue or if I didn't cover them up right or what .... 
Ok, same question... when did you plant?
I grow mine 2 ways (I switch throughout the years):
I either trench them... dig long deep rows, just cover the potatoes, then when they sprout over the soil line I cover them with more dirt. The sprout up again... I cover them... so on and so forth until there is actually a mound where there was once a trench. Like Barefoot said, the potatoes grow up the vine, but under the ground so you gotta offer more ground going up from the potato seed.
I do the same thing, but with buckets other times. Not this year though.
This year I planted the last week of February. (Mild winter and all here) My potatoes NEVER flowered. They just started dying and it looked like Verm Wilt. So I basically threw my hands up with it and quit. Starting ripping out dead plants and I wouldn't have thought about digging anything up when a baseball size potatoe happened to get putted up with the very last plant in the bed. From there, I dug the shovel deep and WALLA potatoes poured out everywhere. I had some huge ones bigger then my hand even. I was impressed to say the least. Best year yet.
Like you though, the no flowering thing threw me off. Same thing with my garlic... no scrapes... I was so disappointed since those are so yummy to eat off the grill.
