House plants are all hybrids or species plants which grow wild somewhere in the world. Try to match the environment from where the plant originated from for the best success. You may not be able to match every criteria for the plant, but every step you take towards the plants comfort will be a giant step towards keeping your friend healthy. Temperature, humidity and light Houseplants, even though they may be of a tropical nature would rather sacrifice a few degrees of temperature in the home than the moisture in the air which they need to survive. Even though the plant may prefer a warmer situation, it comes down to the lesser of two evils, cool temps or low humidity.
Heated rooms tend to be dry rooms, especially if they are heated with forced air, or fire.
Even rooms that have steam or hot water radiant heat will be somewhat dryer. Once the temperature goes above 67 degrees F., the humidity in the air begins to drop dramatically. Keep in mind that because glass is a poor insulator, the temperature near windows will be considerably colder. At night, be sure to close the drapes or move the plant to a warmer part of the room. There are exceptions to the rule.
