Premium mix for Darlingtonia. The same mix we use at Cascade Carnivores for our Cobra Plants is 60:40 peat:perlite, with a handful of medium orchid bark added. The perlite in this mix is fine grade. 1 quart bag. There are no seeds in this mix. It is a soil-less potting mix only. Please note: These potting mixes are heavy! If you do order mixes, please don't complain about the high cost of shipping. Shipping weight just over 1 lb.
