Help- plants for a conservatory

[antumbra]

I am in a new house with a large north facing conservatory and notice that the few plants I owned don't like the room.
It faces North but has an open aspect to East and West so gets a lot of sun. This winter temperatures were as low as 3 degrees, no doubt summer temperatures will be high. What plants will survive such conditions?
I thought about a vine- would that work?

Things like jasmine, stephanotis and hibiscus should work well.

I think peace lilies or tiger lilies would really like a north facing aspect. You can probably grow some chilies quite successfully. I don't have a conservatory but if I did I would probably buy some small citrus trees that wouldn't survive outside. I think a non hardy vine would probably do well too.

Lidls have Stephanotis in for £1.99 a pot at the moment!
