Autumn Blooming Daffodils, Daffodil Types, Fertility, General, Hybridizing, Seedling Narcissus romieuxii x Emerald Sea by Theo Sanders • November 23, 2014 • 4 Comments Emerald Sea can be crossed with diploid and tetraploid bulbocodiums. Some seedlings of N. romieuxii x Emerald Sea are flowering in my greenhouse.
If you heat your greenhouse what temp to you heat it to?
Theo: Very nice. Harold
Bill,
I only heat the greenhouse up to 5 degrees C when it freezes outside.

Hi Theo,
I’m amazed by what you achieve. I so consistently fail with crosses like this.
