Funny, that's how it usually works for me. If I really try to grow something, it turns out terribly. Whereas, stuff I've grown accidentally or just left alone, seem to turn out great.

One year I tossed a handful of pumpkin seeds out in the yard for the squirrels to eat and the next thing I knew I had a big pumpkin patch on the side of the house with a couple of nice looking pumpkins! A couple years later I tried planting some pumpkin seeds just to see if I could duplicate my earlier success, and all I got was a single defective looking pumpkin.
