Classification, origin and description
First name: Sarracenia leucophylla Raf.
Origin: It is an endemic species of the southeastern United States
The plants of Sarracenia leucophylla, like all sarracenia, are characterized by tubular leaves, called "ascids" which can have a height ranging from 20 to 120 cm.
The plant grows from spring to autumn, a period in which it goes to winter rest, no longer producing pitchers.
With the advent of spring, the flowers that are dark red will appear first from the rhizome and only then the first ascids, in order to allow the pollinating insects, to complete their task and not risk being caught before the pollination occurred.

Environmental requirements, substrate, fertilizations and special precautions
Temperature: it must not drop below 0 ° C for several consecutive days.
Light: full sun.
Environmental watering and humidity: during the vegetative rest keep the substratum slightly damp to avoid frosts when the temperature drops below 0 ° C, even if short frosts support them. From the vegetative restart always keep a few centimeters of water in the saucer. It is advisable to use distilled water, from reverse osmosis or rainwater.
Substrate: the optimal substrate for sarracenia must be composed in equal parts between acidic blond peat of sphagnum and perlite. A good quality peat must have a pH between 3.5 and 4.5, 1% nitrogen, 1% organic substance. For some years now, alternative substrates have also been experimenting with excellent results, such as coconut fiber.
Fertilizations and special precautions: no fertilizers are required for these plants.
It reproduces by seed, division of the rhizome or ascidian cutting, although this technique is very difficult and little used both for the poor results and for the long time necessary to obtain an adult plant.
Diseases, pests and adversities
The most common pests on these plants are aphids, mealybug and red spider mite. The death of the plant, if not treated in time, can also occur due to rhizome cancer.
