I have to D. filiformis <span style='color:red'>{Edit: genus names are always written with a capital letter, even when abbreviated}</span> and I know that they are dormant, but I am wondering if they completely die off, like zero growth on them? I am n. va and I am concerned a bit about all of my cps (this is my first winter with them) not coming back. I have pine needles and oak leaves as mulch. Just some reassurance would be great, if you were to look at the pots, you would think there is nothing growing there...
