My plant came from World Insectivorous Plants in 1980, and the original grew well, flowered, produced seed and was eaten by a slug. Seed germinated freely and continued the line.
Stored seed was probably one of the unlabelled packets that was thrown out of the freezer about ten years ago when the encrustation of deep-frozen nameless stuff at the back started to look like a frightening health risk.
Sometimes it is clear cut, you grow a plant, and then you kill it. Sometimes it is less clear cut. Things just get misplaced, or scraped off the back of the freezer into the dustbin!
