You may hardly see the difference to a real Rose! Such a flower shape is unique in the history of Azalea breeding.
New Azalea varieties have a keeping quality of up to 5 weeks. Even in heated rooms. Especially during the period of opening all buds you should pay attention to water your Azalea sufficiently.
If your Azalea stood dry for a short period you only have to water it well and it will come back. While buying an Azalea you should pay attention to the fact that all buds show already colour.
