It's hard to say. It depends upon when they bloom. They don't all bloom at the same time.

I only had one flowering plant this year and I have been pretending to be a bee with a small paintbrush. I'll have to wait until the capsule opens to see if I was any good.
A quick search on the internet to find out what needs to go where and I was a (big) bee.
If the different flowers come up with not too much time between them, you can take some pollen from the first plant (with a small paintbrush) then put some foil around the brush and store it in the fridge for a couple weeks until your next plant flowers.Never tried it but found that trick on another CP forum.

Sarracenia Northwest has a video on how to hand pollinate them. I saw it last week on youtube I believe....let me look...

Yup, here it is!
