It would be best outdoors. However, if you want to grow it inside, you will need to put it in a South window for best results. They love sun and it will soon become etiolated (stretching for light) in an East window.

Yes, I have mine indoors but any other window than south won't work. Even moving it back from the window 2 feet I get etiolation.

Thank you for the responses! I planted the plant outdoors in direct sun, but took a cutting to try indoors! The cutting rooted and is growing, but I will need to acclimate it to the outdoors since it is becoming etiolated! Thank you!
