Happy New Year to all!
The last flower of 2019 has also become the first of 2020. It is open from 28/12. It is "City Lights" (RL.2005.0035.RR.001).
The plant had the bud since early October: I thought it would be aborted. Instead, despite the low temperatures, it has flourished although small and malformed.
First day:
Today:
Very nice surprise 
how is the temperature in Italy this days?
Hi amadeus,
I live in northern Italy: in these days the sky is sunny. Maximum temperatures 8-11 ° C, minimum 2-4 ° C below zero. The greenhouse is not heated.
I`m interessed in how Long the Flower will last with that temperature.
