Mark 'artificial light' needs to be a grow light if you intend for the plant to not go dormant. It needs a full spectrum.
They naturally go dormant everywhere but in some places the dormancy is very short. Here in southwest Florida I usually still have blooms until Christmas, and by the end of February they start to wake up again, although I don't usually have my first bloom until the very end of March.
Here is last year's bloom on Christmas Day
And here is a March bouquet.
