Did you grow this from seed? Likewise, do you use a particular method when growing it? I’ve tried several times but can’t seem to get this vine going :)

I bought the plants 2 years ago and it seems to thrive on neglect. Takes a year for it to start blooming properly. No fertilizer, been in the same potting soil for 2 years, sits outside in the summer and get watered occasionally. Loses its leave when I bring in the winter and looks like it’s dying but it comes back fine.
