Additions to the list of wild edible plants preservable by the deep freeze method
While the author (Gaertner 1962) has previously reported on the freezing, preservation and preparation of native wild plants of Ontario for culinary purposes, this communication concerns itself primarily with three common weeds: sow thistle (Sonchus spp.), evening primrose (Oenothera biennis L.) and sheep sorrel (Rumex acetosella L.), which might add to our winter diet. Two of the three plants are European introductions, usually considered extremely troublesome when present in the field; the third is a native biennial. In addition, the use of the unopened male cones of pine (Pinus spp.) and spruce (Picea spp.) are described.
