As you see, I grow it in pot. During the summer, it is with the other tender bulbs and the succulent plants such as botanical Sansevieria : sun with some shade and water once a week but in great quantity.
For the winter, I keep it in a room at about 15°C, and the pot is next to the window.
This is only my way to do.
Do you confirm that it's S. variegatum ? I hope best photos in next week.
