Symphytum (comfrey, that pest of pests) merely has fleshy roots, not "underground storage organs". In my opinion, that's not sufficient for it to qualify for inclusion on the PBS wiki. We have to draw the line somewhere, or one of these days we'll be seeing calls for including (say) oak trees on the wiki "because they have thick roots." Almost all herbaceous perennials store nutrients in the root system over winter, but that doesn't make them suitable subjects for the wiki. Yes, you guessed: I think inclusion of Paeonia is a mistake. Perhaps we can refine the criteria for inclusion to include "genera normally sold as dried bulbs (in the non-technical sense) that can handle being out of the ground for months." I can assure all readers that comfrey does NOT qualify: I had a stray seedling turn up that took two or three years careful hand digging to eradicate; the fleshy roots pulled out of the soil didn't last long in the air. -- Rodger Whitlock Victoria, British Columbia, Canada Z. 7-8, cool Mediterranean climate
