Back from Sabbatical?

I/we have plants which seem to swan off on Sabbatical. This Tradescantia has been missing for a number of years. Neither of us can remember how many, but we both agree there have been years when we just did not see it at all. Not only that, but it was in quite a different place when we last saw it - several feet away.
Now it chooses to return, not that I mind, it'll be company for the Ophiopogon we thought had vanished as well.

Interesting that the Spill Chucker accepts Tradescantia & argues about Ophiopogon.
