I have been growing this plant since 14-02-2013 and, so far, it has always bloomed, some times twice.
Contacted the vendor about its name and he replied saying this is a phal Vivaldi, which is a complex hybrid created from a lot of different hybrids.
It has been cultivated as most phals.
I call it phal Ana. It was a valentine's day gift from my girlfriend who is called Ana...just a way to distinguish from all the others in my watering calendar.
