I had a couple last summer in a 2 gallon pot, that weren’t very productive. They took a pretty hard frost before I brought them in and most of the leaves fell off, but they’re starting to come out of it and grow some new leaves/shoots.
I have them under a dangling 23 watt CFL light running 24-7 in the basement, not a lot of light but should be enough to keep them alive over the winter.
Next spring when it starts to warm up, I’m going to plant them in a raised bed or garden spot.
