I was under the impression that tiger lilies are poisonous. Day lillies are a great perennial. Everything is edible. Flower buds are delicious sautéed. New shoots also. And the tubers are like potatoes. Plus it spreads by itself.
Kinda shocked to read some of these posts. I would have guessed most on this site could easily last months if the grid went down. I could go a year easy if I were able to hunt some fresh meat occasionally. You all should get prepared. It's not IF but when the grid goes down.
I have 20 of them. Haven't had the success manufacturer claims but they do work better than planting directly in the ground less time irrigating for sure. Maybe seventy percent survival rate and I have to fill them maybe three times a summer. Using two wicks works best. I get eight inches of rain a year in Colorado
