I buy a pot, buy a bonny lavender plant and plant it. I water it and watch as it sulks - grey and lack-lustre. Then lo' - some lavender self-seeds in an invisible crevice in a stone wall. And look at it!
I know this is called a 'gaura' because when my last one died - in the hard late frosts of last Winter - I was determined to track another one down. Lovely foliage, it grows fast and flowers from Spring to Autumn. What's not to like?
This is one of several plants of this family - know the name but can't remember it just now. It came from a car-boot sale. Lovely varied foliage and the flowers are a bonus
