very nice color
Incredible color! The cross should have amazing color.
Is this now AM or CCE worthy?
That is showing the Northern Hemisphere how to flower a plant! (.... and the rest of the Southern Hemisphere as well for that matter). That truly is a stunner.
It is going to be difficult to improve on this with any kind of crossing, the best you can do is to use it to improve another other than itself.
Crossing it back with a roth, will hopefully retain the dark colour but have bigger better shaped flowers. I also have another nice multi that is opening up at the moment which I think would go well with this William Ambler. You will see it soon.
Use something with a high flower count???
