I always call this 'that border stuff'.
What is it really called?
Oh my God, I get to answer something! If you're talking about the purple and white flowers, I think it's allysum! (Not sure of spelling.)
Spot on
Alyssum l think it is Lilac Queen.
OK - I did put some alyssum in but they were long stems - I'm thinking of the short stemmed ones. I wonder what the difference is.
