Quote[/b] ]For seeds to be started indoors or in a greenhouse, the seed should be stratified in the refrigerator. The method that uses the least space in the refrigerator is to place the seeds in a small plastic bag with a few large pinches of damp chopped sphagnum. Keep the seed in the refrigerator 4 weeks.
Sow the seed on the surface of finely chopped sphagnum moss. Live sphagnum works best but needs to be trimmed back regularly. Don't bury the seed. Place seed about 5 mm apart. If the seed have not already been stratified, put the pot in a plastic bag and store in a refrigerator, garage, or other location that stays between a few to 10 degrees above freezing for 4 weeks.
After stratification, move the pots to a bright, location. You may leave the pots in the plastic bags until the seeds start to germinate. As soon as they start to germinate, remove the pots from the bags or at least open the tops and put the pots in a sunny location or under lights. Darlingtonia don't need as much light as Sarracenia but they do need lots of light to show their best colors.
The plants should remain in pure sphagnum. Darlingtonia grows best in loosely packed long fibered sphagnum moss. Live sphagnum moss is probably best but has to be closely watched as it can overgrow small plants. Top water the plants regularly. Many members put ice cubes of pure (distilled or reverse osmosis) water on the soil surface every day during hot weather. Others pump cooled water into the pots. What ever you do, larger pots will be a more stable environment. Air temperatures and humidity are not major issues as long as the roots are cool.
