Growing Sarracenia in Winter
It is absolutely feasible to keep our young Sarracenia seedlings inside during the winter months. Their care is a very minimal routine of attention and is doable for anyone with a small bit of shelf space to spare. The care routine is in fact nearly the same as that of tropical sundews like Drosera capensis, regarded by most as the easiest tropical carnivorous plant to grow.
Direct Bright Light: You will need to keep your plant under artificial lights to keep them alive and photosynthesizing of course! There are many small desk-top grow-lights available nowadays; Yescom Brand is a reliable favorite among growers. Keep the plants at most a foot away from the lights. Blue, red, and white colors of LEDs work nicely.
Windowsills in winter will not let the correct aspects of light through to grow the plant, and plus: winter sun puts them into dormancy anyway!
Distilled or Low-Mineral Water: A tray under the pot that doesn't dry out, like your gas tank, is the only routine you'll have to worry about.
Just Wait til Spring: Once the risk of frost is past, you can put your Sarracenia outside, where it will adjust to the new climate and grow new leaves adapted to its new climate. It may lose most of its old leaves in just a few days or weeks. New leaves produced outside in its first year and especially after transplantation will be very different from those grown indoors, in the same way that most pampered indoor or greenhouse-grown plants will differ from outdoor-grown ones. The genetic capacity to produce that color remains in the plant and will express itself again most clearly at adulthood, a year or so after attaining flowering size in optimal conditions with full sun and warm weather.
