How long can I expect it to flower for?
Sorry don't know but it is beautiful!
Depends if you mean on the plant or as a cut flower!
If on the plant I would say that one has a long way to go yet, possibly four/five weeks yet providing it doesn't damp off or get frosted!
As a cut flower it depends a lot on room temperature and water changes.
A rough figure would be two/three weeks!
