Ground nuts are amazing. When we first bought our property in 2011 we were thrilled to find that we had a small patch growing on a brushy hillside. We had the idea to plant them next to our herb garden and although we anticipated them "spreading" we had no idea how MUCH they would!!!! Unfortunately because of their invasive growing habit in the wrong spot (our fault), I became quite frustrated with them last year. In 2018 one of my goals is to replant them in a better area where we can appreciate them. The tubers are so delicious. We only eat them cooked, and they are similar to a potato, but more flavorful, and watery. our wild tubers get to be at 2-3 inches in diameter...
Ok, thank you for the info. I need to try to get some started, but I need to find the right place to do it where I can easily put a trellis in for them. That stops them from taking over.
Ooo, it did not stop ours... I hate to be one of those people, LOL. But seriously, it disregarded it and has totally taken over a whole area. BUT i think if you keep the tubers harvested very regularly it might not spread quite so much! I will try to find a picture to show you our patch... Hey, edible and delicious so not so bad as a vigorous vine, right!?
You may be in one of those special places where all the conditions are perfect for it, so it rewarded you with abundance, lol. Down here, we have what is lovingly known as Georgia Red Clay. It can take years to get the soil amended properly, and even then, if you don't work on it regularly, missing just a couple of years can turn it right back to GRC, lol.
