Darlingtonia Californica is native to the Oregon Coastline and Southern interior and Northern California coast line. These plants prefer cool nights. With days occasionally up in the 90’s with no greater than 70F root temperature, they still get 50F night temperatures. Most of these plants have some sort of cool moving water over their rhizomes. We have the best results planting these in pure sphagnum moss. You can also use peat moss and perlite. Be sure not to keep them sitting in stagnant water, they deteriorate when this happens.
This size of plant grows best in a 3-4 inch size pot, 2-3 years away from flowering size.
