It's one of the stocks...10 week or Brompton stocks.

Definitely not night stock - the flowers on that are tiny. Agree with Andy

Thought it might be one of the verbascum, but believe Andy is right

Definitely Brompton Stock and not night scented variety.

The leaves are green enough to be one of the newer dwarf varieties, such as 'Cinderella'.

Thank you every one for the reply
