You're right they technically are the same thing, but I call this Butterwort (Common Butterwort)

And this Pinguicula:

They look different lol.

they do ! Try an experiment - twist off a leaf or 2 of the top 1 ( cos its special ) and plant 1 next to the parent. I'd say about 1/4 twisted end into the sphag. No 2 leaf lay flat and use a scissors to make small incisions along the outside of the leaf. That leaf should be pressed into sphag about 2mm ( not buried ). Both should grow babies if kept moist !

PS - that's if you don't know this already !

I did not know this. :O I tried it. :) I took a leaf off and planted it:

and made small incisions on the 2nd leaf:

And I planted them in sphag. They look funny lol.

the leaf with incisions - lay it flat - sticky side up - on the sphagnum and cover with sphagnum in the middle to keep it all touching the sphag. Plantlets will grow from the incised areas...
You will then have 2 ways of propagating.
Good Luck !

Mine/(some)- all from the same plant I got about 2-3 years ago. Notice the bigger the leaf, the bigger the prey. That's a small housefly that has been caught in the bottom right plant.

Whoa, those are so cool looking! I might have to get some of these guys! I actually plan to build a bog garden next year since there are a lot of species native to my area. I'm particularly interested in Drosera. Will have to add Butterwort on there :)
