There appear to be a number of different colour forms in the UK (apparently there are more than thirty in Australia). Only two forms are listed in the Plant Finder. One is an orange flowered form and the other is sold by Aberconwy as 'Pink Mist'.
Scarlet forms were exhibited at the Chesterfield AGS Show but I have not been able to track down who showed them and they are not among the images from the show posted on the Forum.
Can anyone help with advice about suppliers or, perhaps cutting material for Judy Clark the National Collection holder.
