Evergreen Trailing Plant For Chimney Pot

harmony

Hi, I am looking for recommendations  for a trailing plant for a chimney pot.
Hopefully long flowering and evergreen or semi evergreen.
It is in a sunny sheltered position with afternoon semi shade.
Any colour but pink. Thanks

What about Vinca minor or Campanula porscharskyana (semi evergreen)?

A trailing heucheras would suit, as long as you keep an eye out for vine weevils
