Now, the label says it's a "Cumbria", and on the web, I can see that
this term regroup a wide range of hybrids: related to Oncidium (?) or
Cochlioda x Miltonia x Odontoglossum (?).

My question: unfortunately, I'm leaving for 2 weeks at Xmas. I intended
to switch off my central heating, but I suppose it would mean loosing
the new flower stem.... and I am so chuffed about it that I'm ready to
spend money on heating just to see them bloom! So, what would be the
minimum temperature I could get away with for these new flowers not to
die?


I presume you are talking about Vuylstekeara "Cambria". A tri-generic cross
between Cochlioda, Miltonia and Odontoglossum so a complicated parentage.

Minimum temperatures about 55°F at night and the days 10°F to 15°F higher.
So turn your heating down not off.

It's also not a good idea to switch off all heating in the winter, you may
come back to a frozen pipe situation and a ruined house, a friend of mine
did. :-)
