Stephanie stood upcurrently renamed to Stephania pierreibut most often still marketed under Stephanie stood upis a plante lively climbing at caudex ou caudiciforme belonging to the family of the Menispermaceae.
Stephanie stood up is native to the semi-arid forests of tropical Asia, present in Cambodia, Laos, Thailand, Vietnam; there is a plant over there capable of producing long vines. In Europe, it has become a original indoor plantau tuber ornament topped with attractive round leaves.
If caudiciform plants are often deemed difficult to cultivate, Stephanie stood up is nevertheless a plant quite easy to maintain in the houselike a cactus, respecting its rest period.
Description de Stephanie stood up
What is called a caudiciform or caudiciform plant is a plant that is grown for its swollen stems, either as a tuber, as is the case with Stephanieor a pachycaule plant, of which it is the upper stem, in particular its base, which is thickened as in the bottle tree or adenia. The tuber of Stephanie stood up is underground in its original homeland. For indoor cultivation it is only at half buried : its caudex is thus highlighted and the plant is less susceptible to rot as well.
Stephanie stood up grows from a well-rounded tuber, but somewhat flattened at the apex and base. He can make a few centimeters in diameter to more than 30 cm for venerable plants.
This regular, brown tuber is slightly cracked on the surface; it seems covered with a pattern of thin bark. The roots grow from below, the stems from above.
The place from which the green stems emerge each year forms a kind of central umbilicus. This tuber is a reserve organ that limits the problem of lack of water.
Stephanie stood up goes through phases of rest : it then loses its leaves. Where it buds from, usually only a few stem stumps remain.
On the other hand, during its phases of growth, it emits one or more erect stems, bearing alternate leaves. These petiolate leaves are peltate, almost round, with webbed veins, lively worm, reminiscent in their shape of beautiful leaves of nasturtiums.
The stems are generally not very long in cultivation, even if in the wild they can measure several meters.
The flowers are quite rare in the house. The plant blooms in the form of small bunches of yellowish flowers, arranged in the axils of the leaves.
Fertilized flowers turn into reddish drupes containing horseshoe-shaped seeds.
How to grow Stephanie stood up ?
Stephanie stood up grows roughly like a cactus or a succulent. It requires neutral, well-drained soil: a cactus mix or a house mix including potting soilnot too compact garden soil, aquarium gravel and perlite which lightens.
It is grown in a pierced pot, the diameter of which leaves about 2/3 cm of substrate around the caudex; this makes it possible to inspect the state of the soil (dry or wet) and enhances the tuber. The tuber is only half buried.
This plant is suitable for the house, as long as it prefers to stay above 15°C and that it avoids a temperature exceeding 28/30 °C.
She adapts to a exposition bright, but shadedor possibly with direct sun only early in the morning or late in the evening.
However, a lack of light weakens it.
Watering: avoiding water that is too calcareous, Stephanie stood up is watered during its vegetative period (in leaves) whenever its substrate is almost completely dry, or at least dry on more than the upper half of the pot. When in doubt, watering is postponed: its caudex allows it to resist lack, but excess water (the pot soaking in water from the cache-pot, for example) will tend to cause it to rot.
Once in the beginning of growth and in the middle of summer, the stephania is fed with a littlefertilizer (type cactus fertilizer) in the irrigation water.
If the leaves turn yellow and fall: Stephanie stood up goes to rest. It is necessary to respect this vegetative rest, which means to completely stop the waterings until it starts again.
Theoretically, this season of rest is in late winter and early springbut a plant in our latitudes can sometimes go to rest at any time : give it at least 2 months of completely dry rest. Stephanie stood up can even be “stored” (no light needed) in a cooler place (10°C minimum), if desired.
The foliage of Stephanie stood up is the most beautiful when atmospheric humidity is at least 60%. He therefore likes a bathroom or the kitchen, otherwise he appreciates a misting 3 times a week with fresh water.
Stephanie stood up restart by giving it a little water, more light and raising the temperature a little, but most often this happens quite naturally in spring or early summer. As soon as new green shoots emerge, regular watering resumes.
If you have just obtained a tuber of Stephanie stood up dry and rootless, it can be rehydrated by soaking it for 24 hours in lukewarm water, then half buried and placed in bright light and at 20°C. however, it may take several months to restart.
how to sow Stephanie stood up ?
The seeds of Stephaniefairly large, germinate easily.
Sowing is done between 20 and 25°C, preferably between April and Juneto benefit from enough light and so that the seedlings can have a long leaf season to begin producing their storage organ, a small tuber, before the light fails the following winter.
The seeds are first soaked for 24 hours in lukewarm water.then sown a little apart from each other, in a mixture of light potting soil, perlite and fine gravel (genre aquarium gravel). The substrate must remain light and not settle over time.
The earth is kept moist. Seeds are buried 1 cm.
You can expect germination in 2 weeks and the first leaves in 4 weeks.

The family of Menispermaceae is a relatively old family, the majority of whose species became extinct in the Eocene. Of those that remain, almost all whose gender Stephanie, contain alkaloids and various other particular plant molecules sometimes used in medicine. So curare comes from this family of plants.
