Gloucestershire, United Kingdom
I have two buddleias which I bought as small plants last year. One hasn't grown very much, but has loads of flowers. The other has grown an enormous amount, but has no sign of any flowers at all! Although they are in different borders they are in the same type of soil and have received the same treatment. Can anybody tell me why the big one isn't flowering and if there is anything I can do about it? Many thanks.
