The bulb you will receive similar to the 2nd image, not rooted or sprouted. 5/+cm circumference bulb, most are approximately 2-3 inches in diameter. Each bulb will vary in shape and have differences in texture, which is normal.
Grows in similar form to the Stephania erecta. This caudex plant has annual climbing-stem from its huge above ground tuber. Some specimens can have 400 pound tuber!! The plant is dioecious (male and female flowers occur on separate plant).
The suberosa has a bunched up bottom unlike Erecta, although there's a growth point at the top, the suberosa stem growths are random but still within/around the point. Although sometimes both sides might look similar, one side will have a more protruding look and the top will usually have a more 'sunken' look. Good rule of thumb is, at least 50% of the bottom portion is to be buried in. So you've determined the top side and you've buried them properly. Months and months goes by and still no sprout?! I would usually check the other side of the bulb. Yes, it can happily sprout in soil too! They generally look quite short, with thick pink/pale sprout (almost milky white in color due to absence of light and thick stumpy stem from being filled with water). It almost looks like a tiny bean sprout! Just switch the sides around and continue the same potting routine. You'll notice the sprout will become greener in color in time and taller too - depending on your lighting condition.
Choosing what soil to use can greatly affect how well this plant grows (or if it even grows at all). Since the caudex naturally helps the plant’s roots to maintain moisture, you don’t need to get a super loamy, water-retaining soil. Instead, opt for a sand-based potting mix that is labeled for use for cacti and succulents. “Wake up” your Stephania erecta by letting the caudex soak in warm water for 24 hours, with the little spot where the stalks will grow (the node) facing up. Some start by putting a thin layer of rocks in the bottom of the pot to aid drainage, but others just go ahead and fill the pot 2/3rds of the way full of soil. Place the caudex on the top of the soil (don’t bury it). Fill in the space between the caudex and the pot with more soil (again, don’t cover the bulb on top). Give it some water and voila! Your plant has been potted.
To make the caudex sprout those tall, elegant green stems, the key is humidity. Similar to making seeds sprout, you can put the potted caudex inside a germination dome, which you can make yourself. Simply make sure the soil in your pot is damp (but not so wet that it’s dripping or drowning the plant), then place a plastic bag over the top of it to hold in the moisture.
Keep the caudex in a warm place (between 77 and 80 degrees Fahrenheit) where it can receive bright but indirect sunlight.
The time it takes to sprout will vary, but it can take anywhere from one week to one month.
If you notice the top of the caudex is getting too dry, you can spritz it with water from a spray bottle, but take care not to overwater. And if you are really a gardening pro and want to speed things up even more, you can add some Alpha Naphthalene Acetic Acid (ANAA), a growth hormone, and vitamin B1 to the water you add to the soil to stimulate growth. It is extremely easy to overwater the Stephania erecta. The caudex holds moisture, so it’s best to let the soil dry out almost entirely before watering. In the winter, the plant goes dormant and hardly needs any water at all, so try to resist the urge to water it more than once a month! Like most other houseplants, this one likes bright locations with indirect sunlight. Stephania erecta, like most human beings, is most comfortable at a temperature between 61 and 79 degrees Fahrenheit. To avoid brown, dry, crispy leaves, keep the humidity level of your plant at 60 percent or higher. Give the leaves a spritz of water from a spray bottle from time to time, or construct a humidity tray if your house is particularly dry. Fertilizer isn’t a necessary facet of Stephania erecta care in most cases. In fact, over-fertilizing can cause a build-up of substances that can be harmful to your plant, so unless you want to add just a bit of fertilizer every few months, it is best to just let it be.
