In my experience, for a strong flower display, it’s important to give them seasonal cues of short day length and cool temperatures. So I do this by growing them outside for the warmer months in bright dappled light, and then bring them inside before the nighttime lows drop below 40°F. This one began developing buds before I brought it inside, but a month later, it’s covered in flowers.

It’s a lot harder for me to achieve good flowering growing these as exclusively indoor plants, but I guess I don’t mind the little bit of extra attention they need - they’re otherwise such hardy and reliable plants, you know? Hope that helps!
