I have a question for those who grow passion flowers. The packet says to sow them outside and by the instructions on the pack I could do it now but last year I didn't have a lot of luck sowing seeds directly into the bed. I was wondering is it OK for them to be started indoors in peat pellets? Or are they like sunflowers which need to go outside due to their long taproot? I'm also thinking to keeping them in a container so as not to have them on the fence. What do you think?
