I just bought a Juncus Big Twister on sale and have planted it in a pot. I love its unusual form. Does anyone know if this plant could be brought in for the winter and grown under a grow light or by a west-facing window?

I bought this plant from Lowes a couple of years ago. I've found that it has average water needs, although some say it is a bog plant. I have one planted in a very sunny spot and another in partial shade. Both do equally well. They have grown to about 2ft high and 2 ft wide. They are certainly a conversation piece and can take the brutal summer heat of western Kentucky. In winter I do cut them all the way back, and mulch heavily.
