It's a stray, but a nice one

Who knows where this came from, but I enjoy seeing it.

AV update

I removed the blooms on Feb 24th and added very diluted fertilizer to the reservoir. The result was surprising. Four new flower stalks have appeared. Technically I should remove them once more as part of the grooming process - but I think I willwait and see how things develop. I was worried that thre might have been a mite ready to destroy the plant, but now it seems it's quite healthy and disease free. I have to decide to repot, or groom - probably both in another week or two.
