Got the bright idea to make a small one by my pond

[Missa]

I got a cement mixing pan & mixed some of my clay soil, peat, sphagnum & sand in it. Put it in the ground near the pond.

I'm wanting to put CP in it. I got one of each of what Lowe's had, got home & realized a couple aren't what I was hoping they were.
The pitcher plant is a nep not a sarr ... sounds like the butterwort won't work either .... not sure about the sundew but hey the VFT should work.

I hope.

I'm sure you'll find the perfect spot for them all, no matter what they are...and will get lots of enjoyment!  Just means you get to go shopping again!!

Nepenthes are tropical and will not survive your Oklahoma winters. Butterwort is also tropical and will not survive outside in the winter. You can make mini bogs for them and bring them indoors for the winter which is the only way you will be able to keep them year round. They will enjoy your summers but you will be well advised to adapt them to the outdoors slowly and keep them in dappled sun. Slowly adapt them to the indoors in the fall as well.

Cheers,
Sean

There are several hardy Butterworts (Pinguicula), Sundews (Drosera), Bladderworts  (Utricularia). And Pitchers Plants (Sarracenia). That grow naturally in North America.

I am planning on spending a lot of my summer looking for new native specimens. I have already located a Bladderwort growing wild in a bog area near my home in Northwestern Montana. 
 
I would like to recommend the book "Carnivorous Plants of the United States and Canada," by Donald E. Schnell. I bought my copy from Amazon.com. You can purchase unexpensive used books there.

Sean is right about the Nepenthus, they are not even native to North America. But there are many carnivorous plants that are hardy clear up to Alaska.

Most carnivorus plants require peat and a non alkaline sand, Just to be safe I use perlite instead of sand. Some sarracenias in the north do grow in clay though.

I have seen those large cement mixing trays at Lowes. I'm sure I will wind up with one sooner or later too.   

Happy growing,
Patsy
