What potion do you have to make to get triplets?

I don't think there is one. There's one that says "X feels fertile", but it doesn't seem to do anything special the times I've tested it. I think you just need L3 Medicine and luck, as in the other VV games.

I kept giving the fertile potion, and then the very fertile one (nature faction), hoping for triplets. I bred a father of twins with a mother of different twins. Still no luck.
Then a mama put her baby down and ran for a guy before I could stop her. I ripped them apart, too late, and there she stood with a triple bundle! No potion or putting the dad on parenting first.
Dad was a twin himself, but it probably had nothing whatsoever to do with it. I think I just got lucky.

I don't know, almost every time in VV2 that I mated a twin or trip with another twin or trip, I got twins or trips from them. Not every single time, but probably at least 6 out of 10 times.

I had an event that told me that a fertile potion had 2 lotus leaves and one rose. I am going to try it...

Okay has anyone said yet where the pitcher plant is? What does it look like? I have been all over the place and can't seem to find it.

See the Guides section.

(SPOILER) Map of the herb locations.

thanks for that map! But I have put several villagers over there and nothing. Do I have to be at a certain point to get it? I have level 2 alchemy

The Pitcher Plant is available only with the Nature faction (the Magic faction has a different plant) and is available at Level 2. Click the "?" next to each tech's Buy button to see what it does.

I am only level 1 in magic, all my villagers are dieing and I was needed the shark potion so I could fish with what adults I have left.
any other suggestions then?
