Since pansies can thrive in temperate conditions, you might wonder whether this makes them suitable as indoor plants. Well, that depends. Growing pansies successfully indoors requires three things: ● Adequate humidity ● Cool temperatures ● Ample sunlight You probably will not have a lot of trouble with the sunlight requirement, so long as you have a sunny spot in your home somewhere. As far as temperatures go, remember, pansies bloom most when it is around 60 degrees Fahrenheit. Most homes are kept too warm for this. But if your temperatures are often in the 60s, you might be able to get away with indoor pansies. As to the moisture requirement, you can place a tray under your pansies’ pot and fill it with water and pebbles.
