Planting the rhizome
Plant your rhizome immediately when received.
Getting started -- You can start it in a pot about 4-5 inches (10-12 cm) wide.
For soil, use a well draining mix. I use a mix of 2 parts coir fiber to 3 parts perlite. An alternate mix is 2 parts quality potting soil to 1 part perlite or coarse horticultural sand. Don't add lime to your mix, but you may add in some slow-release fertilizer.
Bury the rhizome so it is slightly under the soil (about 0.5 inch / 2 cm). Add water until it is evenly moist, but not fully saturated.
Until it sprouts, keep it about 65-80° F (18-27°C) during the day, and above 60°F (16°C) at night. I recommend placing a minimum/maximum thermometer near the pot.
An LED or fluorescent bulb kept 4 inches (10 cm) away provides the right amount of light (See: "Growing indoors with LED lights"). Protect from direct sun. It should sprout in about 1 to 3 months, depending on when it went dormant.
Once it sprouts --
Lighting -- This forest plant prefers filtered sunlight or bright shade. Protect it from strong afternoon sun.
Fertilizing -- It has average fertilizer needs. During periods of active growth, feed about every 2 months with an all-purpose fertilizer that contains micronutrients, following the dosage on the package.
Climate -- It comes from 1000-2000 meter elevation, where temperatures are mild all year, and nights are cool. It is reported to grow well in temperatures in the 90s (36°C). Its roots probably can handle down to the mid-20s (-4°C) but it's best to protect it from frost. Indoors, the plant can stay evergreen unless exposed to very cool temperatures, which may cause dormancy.
Watering -- The roots like to be kept moist, but not constantly saturated. So aim to keep the soil evenly moistened. Outdoors, if heavy rainfall/watering is unavoidable, use extra perlite in your soil mix.
Dormancy -- The leaves will drop when the rhizome prepares for dormancy. Reduce the watering when this happens, and keep the soil lightly moist (not fully dry) until it sprouts in a few months.
Flowering -- I believe that cool nights trigger flowering, so when it reaches flowering size (about 1 year), expose it to about 6 weeks of night temperatures below 62°F (17°C). If you do this by putting it outside in the fall, make sure it doesn't freeze (over 40°F / 4°C is best).

Have fun growing them!
