I live in MN zone 4 I'm intrested in buying some north american pitcher plants and some venus flytraps from cailforrnia canivores in either march, april or may. i would gradually intrroduce them outdoors, my question is when is the best time to order plants.

Why isn't any buddy answering this thread

That's odd. I check out the Ask a Question forum frequently, and only just now saw this question. I don't know the answer, but you'd for sure want to wait until you didn't have to worry about the plants getting too cold in transit. Have you tried asking the vendor? If they're reputable, they would surely want the plants to get to you in good condition. I'd love to try a Venus flytrap again. We had one when I was a child, but it got fried from sitting too close to a sunny window.

They do need to be kept fairly warm, so again you'd have to wait until your night time temperatures are above 55deg. or so. If the plant sat in your mailbox overnight on a cold night (and where you are, nights can get cold even in summer, right?) they would not be happy.

Once they're grown they may be a little more hardy but you'll still need to bring them in for the winter once the temps are cold like into the 40's at night.

Well, the question has only been up for 3 days and this is a busy time for a lot of people.
Sorry, I did see the question but didn't answer because I was thinking something like "why is the poster going to buy them from California when there are growers in their own state; they should buy locally and support a neighbor" and then I thought about the many carnivorous plants that are native in your state and well, I did not think mine would be a helpful reply.
Good luck and I hope you are successful.

@Maiden This is the person who would have an answer to this question. Lots of good information over on the tropicals forum. I been thinking of getting a few of the pitcher plants as well but will wait for my local nursery. If I understand right there are some hard forms, well in my area zone 7.

North american pitcher plants may still be in hibernation mode right now, so I guess you can order them, but they will not be awake yet.
As for other types of carnivores, wait till temps are in 55F.

Hello :)

You can buy them right now, and put them outside slowly over the next few weeks.

By the way CC is a great place to buy plants. Dallas(the owner) is a personnal friend. They sell only perfectly healthy plants, and they will give you all the advices u need for the genus you will buy.
