|Most cp's compete for space in bogs and cp's almost always loose the battle. You could plant most species of cp's without worry almost anywhere.[/QUOTE]|
On the contrary, many CPs do well in bogs - if they didn't, they wouldn't be there in the first place. I think Sarracenia purpurea has the potential to spread aggressively in Irish bogs - when the conditions suit it it can multiply very fast, and I wouldn't like to see it introduced outside its native range. I think U. inflata has been introduced into lakes in Washington state, where it is making itself a right nuisance. Just because they're CP, doesn't mean they can't be invasive in the right conditions. I agree VFTs are unlikely to cause much harm, but other species could.
