My passi, has really been putting on a show this summer. It is huge and full of blooms. This is my first year for a Tropical Passi so I am wondering how I will over winter it. Usually the end of Aug I start thinking of that in early spring I just think how lovely it would look in my garden. I could cut it back and tuck it into either the GH or the house but last year thing were pretty full around here. I was wondering can you let them go semi dormant?
