Hi Patrick,
Thanks for the comments. I am quite happy to take corrections and I put the sources of my information there so that others could see it and decide how much weight to give it.
I am aware that there is a lot of conflicting information over the ploidy of 'Red Velvet'. The RHS registry supplement 4 does say it is 4N, so considering that is a relatively recent update, I took that as my primary source.
If you have the time, I would be very interested in anything you can add to/correct on my list.
Kind Regards,
Joshua.
