low end of pygmy temps

how cold can pygmy sundews take it? I spread some gemmae around in my bog bowls here in ATL and so far they are growing like mad - better than the gemmae I started under lights. Of course, the question is now, can they take winter?
 
I really am not a pygmy expert, (I only have two that I have no idea how they grew in a pot, ... really I didn't plant them) but I would think it would depend on the species. The two that i have grow outside where it gets down to 50 sometimes 47 at night. So I would say consult a CP book, or ask a sundew expert. Tamlin Dawnster should be able to help you or jimscott.
 
Prime pygmy Drosera areas. Temps are in centigrade:
D. scorpiodes

D. echinoblastus

Do a quick search on your species here:

Then pick WA (Western Australia) from the page below, and move the navigator to the area shown on the above search and find the stations closest to the the locations shown from florabase. Click on those stations for the statistics.

D. scorpioides can handle the upper 30°F range. They even got snowed on once and survived. I haven't wanted to repeat that unintended experiment though. I start taking my plants inside when the temps get lower than 38°F.
 
According to the charts from above for D. scorpiodes the lowest recorded temp since 1971 was -1.0C (30.2F) and the highest 45.9C (114.62F). Just remember these go dormant in the summer and fall.
 
these are x Lake Badgerup (sp?) and my plants inside produced gemmae sometime this past winter which I then spread out into my bogs. Right now we are getting days in the 90+F range and they are growing like mad. I am not sure what to do when it hits around 20F in the winter. How can one store gemmae long term (few months)? Possible?

Gemmae only last a few weeks http://www.carnivorousplants.org/seedbank/species/D_pygmyMore.htm

"It would be too difficult to list pygmy gemmae on the Seed Bank list. There is usually a very short window when they can be shipped easily. They can be stored in the refrigerator for a few weeks but I try to avoid that. If I have extra gemmae, I sometimes include them as a bonus in seed shipments during October and November. If you would like some, ask me about it then."
 
I had my collection of them in the unheated stairway sill this past winter. Temps were as low as the 40's.
 
They can take pretty much anything above freezing or slightly below for short spells (but not advised). These are tough plants, and I don't recall ever losing a species with temps above freezing,
