I've been using 'Edith Holden' for a couple of years for my breeding program, hoping to get an interesting color. So far, though, the germination rate with 'Edith Holden' has been pretty much hit or miss, depending on the cross. As an example, this year the germination rate was extremely poor, and I only got around twelve seedlings total from a couple of crosses I made. :(
The problem that I've encountered with using 'Edith Holden' is that, no matter how high the petal count of the roses I cross with, the results almost always have very few petals. Although many of the seedlings have very interesting colors, I don't feel that I can keep them for later breeding since generally they are only semi-double and have no fragrance.
This one, however, caught my attention.
This is a cross of 'Benjamin Britten' x 'Edith Holden.' (first flowered in 2010)
It's got a great dark purple color, almost like grape juice.
Like I mentioned, I am currently trying to get fully double flowers with an interesting color, so I would normally discard seedlings that have less than 25 petals on their first flower out of hand. But this one caught my eye!
I think that I will hold on to this one and see what it does for me.
