Justicia rizzinii

Anyone been able to grow this outside (even if cut to the ground and reshooting in Spring)?

It's advertised as a conservatory plant but so is Rhododendron simsii, and Gardenia but they seem to do ok.

Thanks, in advance.

 

Stephen - as you had no better replies I checked my bible out. As it is apparently a winter bloomer I reckon indoors is the only option.
