Q.Passion Flowers?

carlrey added on June 6, 2011 | Answered

Living in Western New York (Buffalo – Niagara Area), can I grow a Passion Flower vine tree year round outdoors? I know it is an annual but will it survive cold winters? Will I have to cut it down, dig it up and bring it indoors for winter or will a heavy mulch cover protect it from the winter cold/snow?

If you live very near the falls so that you are in zone 6, you may be able to get a standard purple passion flower to survive in the ground year round if you plant is somewhere sheltered and it is mulched well in the winter. This is the lowermost zone that it can survive in and the purple passion flower is considered to be the hardiest.
