I've never grown it but isn't it somewhat close to D.cistiflora ? Maybe splitting dormant roots would work.
n.flava has coloured up and i really like the subtle shades on the peristome
my d.regia root cutting plantlets dramatic reaction to some powdered bloodworms
and BINGO ,i finally managed to get d.cuneifolia leaf cuttings to strike
and whilst my head was in the propagation tray i took a pic of some d.hamiltonia leaf cutting plantlets 

its only took a bit of sun for d.hilaris and d. cuneifolia to start getting the nice red pigment back into their leaves
little ceph seedlings putting out their first pitchers
n.truncata has put out a larger pitcher
attenboroughii newest
really like the patterns on burb lids
d. hamiltonii
and d.slackii 

first time darlingtonia has flowered for me
and my cephs are flowering,this is a two year old plant from a leaf cutting
this year i have managed to get p.cyclosecta through dormancy without killing it
p.esseriana waking up
and x tina
and filiformis all red ,i had loads of these seedlings last year and only one seems to of survived,really hope a few more will appear
