needrain said:I think it's definitely not K. luciae. To me, as far as I can see in the photo, it looks like Crassula ovato that has been growing under lower light conditions resulting in more spacing between the leaves and with the leaves a bit more elongated than when grown with more light. But I'm no expert and am just comparing to what I've seen that I've grown.
needrain said:Didn't realize the leaf was that long. True, I've never had one grow a leaf of that size. I'm not familar with a trailing type jade. The general shape of the leaves, the texture and the red tinted edges all look like the C. ovata leaves that were on plants I've grown. How long have you been growing it? Different growing conditions can result in quite different appearances in the growth of plants, sometimes.

I control its growth by defoliaging and limiting water and fertilizer in a small pot. It is still outside even when the temperature is below freezing in early morning. However, it your plant has always been indoor, I would not recommend putting them outside now.
