These plants, which are a twisted trap leaf emanating from the root, cannot leave anyone indifferent. With their silhouette and colors, sarracenia resemble fantastic unearthly plants. Few other exotics can compete with sarracenia in extravagance.
The Sarraceniaceae family consists of 3 genera:
- Darlingtonia (Darlingtonia) containing 1 species,
- Heliamphora - about 15 species,
- And the most interesting genus in the family is the genus Sarracenia, which includes about 11 species.
These perennial, rhizome, marsh grasses are among the largest insectivorous plants. The lower leaves of the sarracene are scaly; above them there is a rosette of several large short-peted trapping leaves, transformed into peculiar tubular jugs or urns with wide openings at the top.
The genus Sarracenia is endemic (with limited habitation) to the Atlantic-North American Floristic Region. One species, Sarracenia purpurea (Sarracenia purpurea), was introduced into the swamps of Central Ireland, where aklimatizirovalsya well.
Large, bright, flowers with a double perianth are carried over the jug-like leaves on a strong leafless peduncle, one (rarely 2-3) for each individual. Sarracenia is characterized by a giant, unusual shape, umbrella-shaped column with small stigmas under the apex of each of the lobes; it is especially great in the purple sarracenia.
Some species, such as Sarracenia yellow (Sarracenia flava), sometimes form on marshy ground extensive thickets. Ribbed tubular jugs of this plant, extending almost vertically from a powerful horizontal rhizome, can reach a length of 70-80 cm.
In other types of sarracenia, pitcher leaves are much smaller and, as a rule, do not exceed 10-40 cm. Most of them are variegated in purple-yellow-green colors. Particularly striking is the pattern around the opening of the sarracenia jug, which makes the entrance to the trap visible from afar. Each trapping leaf on the side facing the stem bears a pterygoid fringe, the upper part of which looks like a cover. This is a kind of "umbrella", cut by nature from the upper blade of the leaf blade, slightly covers the hole, preventing rainwater from entering it.
The insect, attracted by the wonderful aroma emitted by the nectar-bearing glands, which secrete large quantities of nectar, sits on the trapping leaf and begins to slide down the honey path lower and lower. The walls of the sarracenia trap leaves are covered with hairs that allow insects to move only inward. Soon, the insect gets into storage traps, from which it can no longer get out. Insects dissolving in the digestive juices provide the plant not only with nitrogen, but also significantly increase the content of calcium, magnesium and potassium in its tissues.
Birds often use the tubes of these plants as feeders, pecking out insects that have not yet decomposed. According to the testimony of some scientists, the remains of small tree frogs were found in the tubes of the sarracenia.
Some insects have adapted to life inside the trapping apparatus of insectivorous plants, secreting substances that oppose the digestive sap of the plant. D. Fish (1976), who specially dealt with this issue, writes that the night moth and its larvae, the larvae of the fly fly, as well as the wasp sphex, which even builds nests inside the urns, live in the traps of sarracenia. Uninvited guests not only destroy most of the insects that have accumulated in the urns, but also damage the tissue of the leaves, from which they simply cannot function as traps. In this way, significant harm is inflicted on entire populations of one or another kind of Sarracenia.
Some types of sarracenia are very decorative and have been cultivated in some countries for a long time. Especially common in the culture of Sarracenia yellow is a spectacular perennial with large pale orange flowers and succulent, gracefully curved pale green jug-like leaves. In room culture, this plant, with abundant watering and appropriate care, can live even without insect feeding. No less popular purple sarracenia, whose flowers have an excellent scent of violets.
In the leaves and aerial organs of several species of sarracenia, the alkaloid sarracenine was found, which has found application in medicine.
Caring for sarraceny at home
Soil for sarracenia
Under natural conditions, sarracenia grows on bolts, river and lake banks. At home, you can plant it near an artificial pond or pool. If you decide to plant sarracenia in a container, use a 4: 2: 1 mixture of peat, perlite and building sand. This composition is most similar in its properties to the soil on which it grows in the wild (pH 5-6).
Never fertilize the plant under any circumstances. This can be disastrous for her.
If you planted sarracenia near a pond in your garden, then additional watering is not required for it. The plant will receive the required amount of moisture from moist soil. If you are growing a caracenia in a container, then it needs to provide intensive watering. The ground must be constantly moist.
Only in winter, when the flower enters a dormant state, the intensity of watering can be reduced. During the period of active growth of sarracenia, a pot about 25 mm high should be constantly in the water, from October to April, the plant is watered once a week. After transplanting, the intensity of watering increases significantly - up to daily.
Sarracenia is a sun-loving plant. For normal growth and development, she needs 8-10 hours under the sun. Indoors, place the container with the plant on the south or west side, or provide it with good fluorescent lighting.
Pots and containers
Since sarracenia prefers well-drained, moist soil, a container or pot for it should be chosen one that will suit these conditions.
Glass or plastic pots with drainage holes to drain off excess water are best suited for this purpose. Porous containers are not suitable for growing sarracenia, as they absorb too much moisture.
Sarracenia, with good care and in good conditions, grows very quickly, so over time, the roots can become cramped inside the pot. Therefore, it is advisable to regularly transplant sarracenia into the largest container. The transplant is best done in the spring, after winter dormancy.
Reproduction of sarracenia
Sarracenia propagate by seeds, which are conveniently sown in Petri dishes on peat, followed by picking into pots. The seeds must be subjected to cold stratification from 4 to 8 weeks, without stratification the seeds will not sprout.
Sarracenia yellow perfectly reproduces by segments of rhizomes, which, in principle, explains its simplicity in culture. However, this operation is performed only when the plant reaches a significant size. With too frequent division, the sarcenias become smaller and may even die.
Pests, Sarracenia diseases
In summer, usually aphids or spider mites, rot (botrytis mushroom) may appear in winter.
