  1. Fantastic Mr Merlyn

    By Jim Wilkie 21-08-2016

    Received free seeds, never heard of the plant. Grew the plant easily, and now have a magical display of flowers at back of the border. Recommended for every garden, and attracts the bees in abundance.

    Received these as free seeds, they are magnificent! Add height to the bed and I have never seen so many bees they absolutely adore them. Easy to grow would recommend everyone to give them a try. Colours also beautiful
