Does anyone know?

Does anyone know very much about P. crystallina ssp. hirtiflora's? I would especially like to know if they need dormancy. If you know anything please post. Thanks you guys.

I don't grow this species yet, but a paper in the UK Carnivorous Plant Society Journal in 1998 recommends keeping these plants overwinter at similar temperatures to Mex Pings, around 10C min. P. crystallina is fairly intolerant of low temperaures and losses are very likely if kept unheated over winter.
