I've had this plant for over 10 years. I've had it outside in the summer, but that doesn't seem worth the effort. It now grows in my sunroom where it is ceiling height and thrives best directly under the skylight. It has blossomed for the last three years. The first time it bloomed I discovered a flower on the floor and other spent ones on the vine. The second bloom had more flowers but were not very visible. It was growing intermingled with a 'McCain'� Passion vine which has since died. Perhaps this year I will be surprised with an abundant display. I was ready to throw it out, but now I'm glad I didn't. I was attracted to this plant because at one time it was listed as not affected by pests. It did however get an infestation of mealy bugs. I have found success with a systemic pesticide...not sure how ecologically friendly this is, but it is inside and it works.
