I just added it
Camellia 'Winter's Dream'
Anyone can add missing plants to the database (and I see you have done so). Go to the Plant Database main page and click the " Add a new plant to the database.
The only two required items needed are genus and cultivar so in this case:
Genus: Camellia
Cultivar: Winter's Dream.
If a common name is different than the genus name, it's optional to add that.
