This time of year on a brug thats been brought inside that's very common. You'll find pictures of brugs that have been brought inside for the winter that have no leaves but still have a flower or two on them. It's a reaction to the short daylight hours and the shock of being brought indoors. Even here in south florida where they thrive year round, if we get one of our cold snaps my yard look like fall in NY...i currently have over 100 brugs..
