I finally have time to post these plants for ID. All plants from Alpine garden 1.Centaurea diffusa or something else? Food garden. 2.It looks to me like Mimulus or something from Plantaginaceae or Scrophulariaceae? Food garden. 3.What kind of Gaura? Food garden. 4.I found, this is Bryonia dioica
I think that is an (unaccessioned) Centaurea hypoleuca 'John Coutts'. That was what I tentatively identified it as last week, anyway.
That one should be a a 60 cm plant with 6 cm, deep pink flower heads above 15-20 cm leaves - the UBC plant is surely something else.
