Sarracenia Purpurea spp. Venosa.

I am a little caonfused on Venosa. I had it out in an uninsulated porch but the pitcher's water froze in them so I thought it was way too cold for it. So my question is what is the known cold hardiness of Venosa. Please give me a range. Here is an example. Venosa can take 45 F down to 10 F for dormancy. That is how I would like an answer for this question. Thank You.

I don't know, but I can guess "educatedly"!
I have heard venosa's cold-hardiness can be as low as 0(F) for short periods uninsulated. If you were to plant your venosa in a pot or bog garden in the ground and mulch it with several in. of say pine needles inwinter, late fall, and early spring it could presumably withstand even cooler temps. What you could do is research what venosa experiences in its natural habitat, which I don't know.
My surmised answer:
(possibly) 0F to (no more than) 50F

Thanks Chris well I put it by a cold or cool wall and the soil is pretty cold so I think it is fine. TThanks. Nep.G.

S. purpurea venosa can take anything you can throw at it, as mentioned above by  Dionaea if its roots are protected for long term cold spells.  Ture with S. purpurea purpurea too.
S. purpurea venosa occurs in habitat well into New Jersey where it mixes with purpure purpurea, hybrids are more common.
It is S. purpurea burki that has a hard time with long term cold weather.  But in the past week the Pan Handle of Florida (range of most Sarracenia) has been down into the teens on several nights after a warm December.  Now that trend is reversing and days are back into the 70's with nights climbing into the 50's.
By looking at these temp changes you can see that the plants can take the cold weather, however you can also see the pattern changes quickly and isn't long term.
Plants here continue to grow slowly, with air temps to about 38 on many nights, with frost on a couple AM.  The seedlings have never entered into a true dormancy.
Regards,
Mike
