the starlings will eat them .
as long as you water well for awhile they should be o.k although its raining buckets here in the west.The wind is your worst enemy when transplanting or moving plants.
they like rain water and only water when really dry.They need to be in sunny but shady spot plus they need feeding when in flower.Also they need a rest period before they flower again .
I have grown a passion flower plant from seed.
I had one for years but always put away in shed as plastics or resin types have a shelf life and do go brittle after a time.
a montania type are very hardy and strong and can take most things.
have got it lime free soil and it is also important to water in autumn and in spring as feed also.
Its good idea to go and visit these gardens to ideas on what you can do as well enjoy.
I think you have done a good job,well done! wish I could see some where I am ,have not seen any for years .
A crane fly, the starlings love to eat the grubs ,they are usual about autumn time and they do not live long and don't do any harm .
