Hey, you've got the single flowered pink one! Want to swap one for double flowered pink? =)
I'll collect some seeds for you if you like Evert. The front garden we have is brick hard clay so I can't dig until the heavy rains come and then it's too wet LOL.
OK... But let me know if you can swap a plant sometime, they are easier to get started ;)
