Sounds like a Borg "designation".

"Resistance is futile."
"First of two".
Given the famous Blip unsearch engine IS working OK, I can trace this group of plants back to during/before 2010, inasmuch as we'd had them long enough then to achieve 1st flower.

Seems, as I said at the time ..."A friend of ours had a thing about "Air plants" (Truth be told so have I/we) SO .... 
When we bought one for her birthday we also bagged this un for the Bathroom window-ledge."

So that's in time for mid MAY 2009 or 2010.
They seem to have been up aplenty:-
2010, once:    2011, thrice:    2013, twice:    2014, once:    2016, four times.

"First of two" on two counts. ...
First time I've had two plants flower, more or less together.
The "two" part refers to the fact that the second plant has yet to flower; which will occur in the foreseeable future, and no doubt merit a second Blip.
In the intervening years, the right hand one has become a seeable eight, the centre one has been replaced once/twice, most recently early last year, the left hand one has become three and I've added a fourth to fill the gap at the back.

Addendum. Whilst checking the "Lynx" worked I see the right hand one has flowered once this year already.
