Strict adherence to the cultural needs of this plant is essential. In residential areas, this plant is best grown in the consistently moist soils of an artificial bog garden. The bog garden should be prepared in advance of planting. In the St. Louis area, the bog garden should be sited in a protected location with a winter mulch. If a bog garden is not available, then growing plants in containers may be the next best option. Plants require full sun. In part shade, leaf coloring does not develop as it should and pitchers droop. Plants need an acidic, humusy muck that is constantly damp but not watery. Soils must never dry out, but plant crowns should not sit for prolonged periods in water. Soil recommendations include Canadian peat or mixes of peat/sand or peat/perlite. Irrigation hoses and underground liners should be considered. Plants have a horizontal rhizome. Plants flower in spring, produce new pitchers in spring-summer and the pitchers mostly die back as winter approaches. In cold climates, trim leaves back in winter as pitchers die, but only trim dead tissue. Soil may be mulched with pine needles in winter to protect plants from cold temperatures. Most reproduction comes from continuous budding along the rhizome as opposed to self-seeding. Easiest propagation is by rhizome division. Plants may be grown from seed with effort, but will not flower for the first 4-5 years. Plants may also be grown in pots/containers (plastic best) placed outside on a sunny deck or patio area. Container soils can be 50% peat and 50% perlite/vermiculite. Potting soil and/or fertilizer may kill the plant. Containers should be placed in a tray of water that keeps the soil constantly moist. Containers may be overwintered by inserting them to the rim in soil in protected locations. Dig up containers in spring to place back in full sun areas. Containers may also be brought inside in winter with somewhat reduced watering. Plants need full sun in the growing season and cold temperatures in winter dormancy, hence they simply do not grow well as houseplants. Do not collect these plants from the wild.
Sarracenia rubra subsp. jonesii (sweet pitcher plant or mountain pitcher plant) is native to mucky soils of seepage bogs in a very small mountainous area on the North Carolina-South Carolina border. Subsp. jonesii is on the federal endangered species list. This is a stemless herbaceous perennial that grows in full sun. Modified leaves form upright, slender-fluted pitchers of variable height ranging from 15” to 24”. Pitchers are narrow with a somewhat horizontal lid that prevents most rain from entering the tube. Subsp. jonesii pitchers emerge green maturing to bronze or copper with maroon veins. Summer pitchers are more vigorous than spring ones. Lids are attractive landing sites for flying insects. Insects are lured to the pitchers by the attractive leaf colors and nectar. Nectar reportedly has a paralyzing effect on insects. Each pitcher is slippery inside, and insects fall down the tube into a digestive juice liquid at the bottom of the pitcher. Insects decompose and nutrients are absorbed. In spring, a single flower rises on a leafless stalk (sometimes two flower stalks emerge from the same rhizome point) to about the same height as a mature pitcher. Flower stalks are crooked at the top, and the globular, 5-petaled, dark red flower hangs down. Flowers typically are fragrant. Each flower is followed by a 5-parted seed capsule. This species infrequently produces slender, linear, winter leaves (phyllodia).
Genus name honors Dr. Michael Sarrasin de l’Etang of Quebec who reportedly sent the first pitcher plants to Europe around 1700.
Pitcher plants are described as carnivorous plants because they trap and kill insects (e.g., flies, ants, beetles, wasps) and similar prey (e.g., mites, spiders) by luring them into trumpet-shaped pitchers (modified leaves) where the insects become trapped and die. Nutrients from the decayed pest bodies are absorbed by the plant as nourishment through special cells located at the base of each pitcher.
Plants will do poorly if specific cultural requirements are not followed. Protect from strong freezing winds. Winter hardiness is generally not a problem in the St. Louis area for this plant. Feeding plants manually is not advisable. Do not fertilize plantings. Watch for aphids, scale, mealybugs, moth larvae, leaf spot and root rot.
Bog garden is best. Also may be grown in containers, greenhouses or as an indoor houseplant. Perhaps too tall for terraria. Growth in containers as an indoor plant can be difficult because of the need for growing season sun and winter dormancy. May be grown outside in low spots or other continuously moist locations, but this can be difficult and is not recommended.
