When your package arrives, promptly open it and find your plant. It will be packaged bare-root and labeled. It must be unwrapped and placed immediately into its new pot. Carefully separate the cups and tape and unwrap the plant from the plastic bag with the paper towel in it.
If you don't have soil or pots ready and you have already unpackaged your plants, Sarracenia can survive for brief periods of time sitting in pure, low-mineral/distilled water with their growthpoints above the surface, but under no circumstance will they tolerate even slightly drying out.
Once you have the appropriate soil (50/50 sphagnum peat moss and perlite), hydrate it and mix it well. Let your soil sit for 10 minutes after wetting it so it can thoroughly hydrate. Use a drained container with your plant's growthpoint exposed to the sun. Place your potted plant in a tray of low-mineral water, and don't forget the label!
If you've received your plant in winter, keep it indoors under bright, direct artificial light until you are past the date of last frost for your horticultural zone, when you can place it outside.
If you've received your plant at the beginning of fall, check to make sure you have at least two weeks before first frost in your horticultural zone before setting your plant outside. You may acclimate your Sarracenia under a covered structure such as a porch or coldframe in this case if you are experiencing early cold weather.
At any other time of year (their growing season) you can place your Sarracenia outside. Acclimate your plant to your new conditions by offering it morning sun or partial afternoon sun for the first week or so. New growth will itself acclimate to your conditions.
Because their accelerated growth regimen at American Pitcher Plant enables them to retain old foliage beyond its normal lifespan, you may find old leaves rapidly senescing by turning brown. This is normal and you may remove them after they die off. New growth will be unaffected, but as the plant matures and adapts further to your environment, it will change in color, shape, size, and growth rate. If all their needs are met, you will be rewarded with a beautiful Sarracenia.
Do not attempt to keep Sarracenia as indoor terrarium plants. While their seedlings can be kept as indoor curios under strong artificial lights for the first two years of their lives, most Sarracenia (with the exception of S. rosea and S. psittacina) are outdoor container plants, feasible as wetland landscape plants and pond ornaments. They require cold dormancies in winter for a minimum of 2 months. They thrive as coldframe plants in most climates, provided they are allowed a cold dormancy in winter.
