Perhaps Glowing Amber?
I’ve raised a few bicolors from very “wide” crosses. I think many members has said this before, and I’ve read this in older rose books and annuals.
I will talk about my rose Prospero X Goldmoss.
Prospero is a dark purplish red mauve with an intense fragrance. Its parentage consists of old red roses. Not very strong in cold climates, but it’s disease free and strong in my garden.
Goldmoss is the first strong yellow moss rose with remotancy. It parentage consists mainly yellowish floribundas and moss rose hybrids.
Originally, I wanted to mimick something of Paul’s work, although-- I’m happy with the results I’ve obtained.
Neither parents are bicolor, but they gave something that looked a little like Glowing Amber in colors. However, this seedling isn’t very color fast-- but it doesn’t “blue” like both its parents. (Goldmoss doesn’t really “blue” as much as get spottled.)
The flowers themselves aren’t very mossy. They do have something of moss, but it is so minimal that I don’t think it would be fair to call it a moss rose.
My seedling is also not fragrant, which disappoints me. However, it seems stronger than Prospero and has the same cycle blooms like Goldmoss.
I’ve thinked about introducing it because it grew in a horrible place and did well enough to survive. When I planted it in a good place with good soil and sunshine, it started to grow wonderfully. I’m constantly pinching off flowers so that the energy is spent in growing the plant.
Other crosses that gave me bicolors:
Livin’ Easy X Rugelda
Golden Angel X Fragrant Plum
OP seedlings of Scarlet Moss
