At this point I have about 10 gallons of plants that I dug complete with tubers, leaves, and adjacent soil in the black plastic bag and another 5 gallons still in a bucket. There are more in the ground but this is a good part of what was there. I do patrol down the intermittent drainage creek looking for outliers, where tubers have floated downstream and rooted where they come to rest. Microwaving would probably work but A) mine is not large enough to more than a quart or so at a time and B) wonder what it would smell like - oven-baked soil smells pretty rank. And my husband already complains about "your stinky plants" - Fritillaria imperialis and Dracunculus vulgaris Brian, I concur that plants I don't want to kill always die rapidly at the smallest faux pas such as the oversight of leaving them in an open tray. Those I want to kill (like Ranunculus ficaria) seem immortal. Today someone told me he did eat Ranunculus ficaria leaves, mistaking them for Caltha palustris. That's what comes of reading Euell Gibbons "Stalking the Wild Asparagus" at an impressionable age. My friend was young and foolish, survived the misidentification with no ill effects because - he thinks - the leaves were cooked rather than raw, in a salad. Not worth it, to my mind. Keep those suggestions coming folks. I'm happy, happy with the responses so far. Judy, who want to earn the epithet of "bane of the lesser celandine"
