Has anyone used ‘Muriel’, apart from Ralph Moore himself? Also are there any nurseries that currently list it?
I have, yes. Mixed results. It is a tetraploid that gives mixed ploidy pollen. I do not know any nurseries that offer it anymore, but you would be well advised to contact Burling Leong first.
Have you read the article David Zlesak and I wrote on the Bracteata Hybrids a few years ago?
