This is my Zigo...have it for several years and I keep it 99% of the time outdoors. It stands temps as high as 40ºC in summer but when it gets below 10ºC in winter I put it indoors (mostly at night).
The first time it bloomed its fragrance spreaded to the entire house but this year, although fragrant, it's not noticeable unless you actively smell it. I believe it's due to lower temps happening now around here.
