I have my P. sethos <span style='colorrange'>[Edit: P. 'Sethos']</span>growing outside along all of my other plants and I was wondering why it hasn't started producing it's winter leaves yet. My D. intermedia and D. filiformis var. tracyi have already started their hibernicula and all of my other plants have slowed down in growth, however my P. sethos <span style='colorrange'>[Edit: P. 'Sethos']</span>is thriving.
