Last year I saved some seeds from a passion fruit, not the small purple on but the large applesized yellow one.I dried the seeds for sometime, chilled them a while then sowed them. I was thrilled that most of them came up. I kept them in the house on a sunny windowsill during the winter and in the spring when it was warm I put the pots in the greenhouse. When I planted my tomato plants I picked the strongest three passion plants and planted them in the greenhouse. Thay are now between 2 and 3 feet and have strong tendrils wrapped round poles. I have no idea what to do next and wondered if anyone knew. I want to move the biggest to a special place in the greenhose, where I can wrap it if need be though the winter, the plants are a lovely glossy green and very healthy.
