I bought this flytrap from a local nursery, the first one I've kept since the one I got (and promptly killed) as a kid. It was mixed in with a bunch of hybrid pitcher plants and being kept in the shadiest part of the nursery (north wall, no direct sun at all), so as you can guess, all the plants were pale and spindly. Since it was only a few bucks and just labeled as "Venus Flytrap", I assumed it was just the regular kind. Looking at photos of this species online today though, it looks like they're supposed to have longer teeth. Are the short teeth the result of being kept in shade and (in all likelihood) watered with tap water? Or is it one of the short-toothed cultivars? What's the difference between 'Dente' and 'Dentate'?
I've had the plant in full sun for 2-3 weeks now, and it's super happy out there. It has opened up a couple new traps and has several more developing fast, and has also developed a bit of a reddish hue.
