The Stephania erecta is a unique plant known for its caudex, a potato-like bulb that grows upright vining stems with round leaves showing prominent veins.
In winter, this plant goes through dormancy, dropping all its leaves. However, it will grow back in spring, sprouting a bunch of new circular leaves.
This plant guide has easy-to-follow instructions on how to make a Stephania bulb sprout so you can successfully grow this fascinating plant in your home!
Stephania Erecta Plant Care
Botanical name: Stephania erecta Craib (Currently classified as Stephania pierrei). Common names: Potato plant, potato vine.
The Stephania erecta was first described by British botanist William Grant Craib in 1922.
The Stephania erecta is a rare caudiciform plant gaining in popularity. If you are lucky you can find the plant for sale in specialty nurseries.
Typically, the Stephania erecta is sold as a bare tuber, without stems, leaves, or roots. You will have to plant it and make it grow into a thriving, beautiful plant.

Stephania Erecta Life Cycle
The Stephania ereacta grows during spring and summer and goes dormant in winter.
Do not worry when your plant suddenly drops all its leaves when winter sets in. That’s part of the natural life cycle, the Stephania erecta survives the dry months as a bulbous caudex without leaves.
- Caudex Sprouting: In spring or early summer, the plant typically emerges from its caudex. This marks the beginning of the yearly growth cycle.
- Vegetative Growth: During the growing season (spring through early autumn), the plant produces its characteristic round coin-shaped leaves on elongated vining stems. It will require regular watering, high humidity, and bright indirect light to support healthy growth.
- Winter Dormancy: In the fall or late autumn, as the days get shorter and temperatures drop, Stephania erecta enters a period of dormancy. During this time, the plant’s beautiful round leaves wither, turn yellow, and drop off. The plant will require less water. Just enough to keep the soil from going completely dry. This dormant phase can last for several months, typically until the following spring.
- Repeat Cycle: With the arrival of spring and longer daylight hours, the plant will come out of dormancy. Give it a good watering and the growth cycle begins anew.
How to Make Stephania Erecta Bulb Grow
To encourage your Stephania erecta to sprout and grow leaves indoors, start with a healthy caudex bulb. Look for a firm and plump bulb without any signs of rot or damage.
It is normal for the caudex to be a little shriveled. This is nothing to worry about, it has been dry and dormant. It will plump up when it gets watered regularly.
Watch out for soft, moldy, or smelly bulbs. These could all be signs of rotting.
Select a shallow (clay) pot that is slightly larger than the caudex. Make sure the pot has drainage holes to prevent waterlogging.

Make Stephania Erecta Bulb Grow - Step-by-Step Instructions
With proper care and patience, you can encourage your Stephania erecta bulb to grow beautiful leaves.
Remember, each plant is unique, and sprouting time may vary.
Materials
- Stephania erecta caudex bulb
Instructions
- Soaking: Before planting, soak the caudex bulb in water for about 24 hours. This hydrates and ‘wakes up’ the bulb and prepares it for sprouting.
- Planting: Plant the bulb in a well-draining potting mix. You can use a mix of regular potting soil and perlite or sand. Plant one-third to one-half of the bulb into the soil. Keep the flatter side facing down and the node on top facing up above the soil.
- Positioning: Place the pot near a window with bright, indirect light. Maintain a warm temperature range of 70-80°F for optimal growth.
- Humidity: Increase the humidity by covering the bulb and pot with a plastic bag or humidity dome. When you see new growth, remove the bag from the pot. Mist the leaves occasionally to provide some humidity.
- Watering: Water very sparingly initially. You can increase watering once you see stems sprouting. To prevent the caudex from rotting, try to avoid getting the caudex wet when watering. Allow the soil to dry out slightly between waterings.
- Patience: It can take anywhere from a few weeks to a few months for the Stephania ereacta to sprout and start growing leaves, so patience is key. Continue to provide proper care, ensuring adequate light, water, and humidity.
