Advertisement With regards to the first point: really. I promise. On soil that almost any other plants can grow on, they exclude carnivorous plants. Remember that the important factor in this case is soil chemistry, which you can't see. This means that cp's are abundant where they're present, but their habitats are few and far between. With regards to the second case: that's fair, but I still wouldn't recommend collection, because you never quite know what development will look like at the end. Plus, you don't have to collect entire plants--you can take cuttings and leave the rootstock intact. Plants taken from the wild are stressed enough that getting them to survive is an upward battle anyway.
