I grow it room temp under a humidity dome. It's the BE-3726 but unfortunately it's very hard to find since it's an older hybrid. They pop up a couple of times a year on ebay. That's where I got mine.

Yep! Ampullaria genes are crazy strong. They're like the basset hound of carnivorous plants, where you know instantly when you see a hybrid, because it looks mostly like an amp with different detailing. These are (in order) ampullaria x raffelsiana, ampullaria x veitchii, and ampullaria x hamata

Thanks yes usually they're some combination of red, green and purple.

And sunlight warms the wet soil faster than it warms air, so there's a lot keeping the soil warm compared to the air freezing the soil.

There's lots of natural insulation going on in wild bogs. That's part of why it can be a pain to grow the same plants in pots, b/c there's less/no insulation. The fact that they're constantly wet is most important, b/c water has 4x the heat capacity of air, so it's hard for air to cool the wet soil.

FWIW this is the range for s. purpurea from wikipedia. They're quite fine with cold. They're either insulated under snow cover or leaf fall. As long as the rhizome doesn't freeze then you're fine.

I'm up north but we see <10 days/year below freezing. I just bring them inside when it drops <30F. Their dormancy is triggered by photoperiod more than temperature.

Also if you're using distilled and have multiple salt sensitive plants, then I recommend grabbing this: www.amazon.com/dp/B00204CQF6 I bought mine in jan 2023 and have been using it since then. Great RO system and you wouldn't guess it by the price.

Yeah the big cream pot has small drain holes, but I stuffed them with long-fiber sphag to reduce the drain rate. The built-in tray holds a bit of water, and I water every day or two. Their planters might not have holes, some people grow them that way. I like the o2 from drainage though.

3 parts peat, 1 part perlite. I use reverse-osmosis water for it, but low-mineral tap water is fine too. I repot every 2-3 years. It likes to stay really wet.

I have had this sarracenia flava potted for >10 years. It's one big rhizome underneath the soil. They really like to be fertilized with a balanced non-urea fertilizer when they're potted. For a pot that size I use a couple dozen grains of osmocote 3x yearly, plus monthly half-strength maxsea.

I would have to dig up the paper, but iirc amps also produce lower levels of the digestive enzymes, depending more on the pitcher flora for digestion, like sarracenia purpurea. It's definitely a unique niche in an already niche group of plants.

It's also a "vegetarian" carnivorous plant. The way it absorbs nutrients in its pitchers is similar to other nepenthes species, but it's more optimized for absorbing dead leaves that it catches as it sprawls across the jungle floor.

That's a sarracenia something making flowers haha
