LFS naturally acidic?

Is Long Fibre Sphagnum Moss naturally acidic? I am thinking of just using pure LFS for my Sundews and all other future cps that I purchase as a planting medium.

As Steve says, sphagnum is neutral. Peat moss is acidic and most CP mixes use 50% peat. Sphagnum is good for a top dressing or for growing seeds.

Can dead LFS only still be suitable as a potting medium for Carnivorous Plants? Or does is have to be acidic for them to thrive?
 
Yes, in as much as Sphagnum moss peat is dead Sphagnum just a bit further down the decomposition ladder and when put in pots looses its acidity over time due to watering etc, so does LFS.
Depending on your source ‘dead’ LFS can carry spores that will grow when kept wet, others are sterilised.

Thanks Steve!
So just checking to be sure if I understand what you are saying is Temperate CP's can be potted in pure dead LFS with no Peat mixed into it, correct? I just don't want to kill my CP's when I move out west :)

Peat moss is the decomposed sphagnum moss. You can plant a lot of different CPs in dried sphagnum moss, temperate ones will be fine too.
In a big, simplified bog, the first layer is the live sphagnum moss, then the dead sphagnum moss, and going deeper you will find the black decomposed peat moss.
