So soon I'll have my garden back in production. For now I am 'scavenging'. I let some greens go to seed in spring, so I clipped some arugula, mustard, and chard from that. 3 oz worth. I had also planted some Jerusalem artichokes in spring. When catalogs say "drought tolerant, plant it and forget it", they are not thinking of the Valley. I fried those suckers by mid-August. I did not expect much, but I checked under one of the stalk stumps for kicks. Monster! I got 1 lb 9 oz of usable tubers from that single original tuber. It's more impressive with pictures.
New estimation of JA's: great. Which is good because I hear you can't get rid of them.
