R. Pteragonis

R. Pteragonis is a primary hybrid between R. hugonis and R. sericea pteracantha, the latter being the well known 'Wingthorn Rose', grown for it's dramatic translucent red thorns. Pteragonis has certainly inherited the same thorn pattern from the sericea side of the family, and some of the yellow from hugonis, although it quickly pales to white when fully open. Pteragonis is quite hardy in all but the coldest of climates and makes for a striking addition to a landscape setting. Height 7 to 10 feet, architecture loose and vaguely V-shaped.

R. Pteragonis was bred in Germany in 1938 by Max Krause. My specimen came from Vintage Gardens, although I understand that they don't always have plants for sale. Best to call and inquire about availability.

R. 'Pteragonis'

"Pteragonis", a R. hugonis X R. sericea pteracantha hybrid by Max Krause, 1938. This was a gift from Gregg Lowery (Vintage Gardens) in 2009. I am attempting to use it in breeding, but without success so far. I think its just a matter of finding the right plant to mate it with. (I doubt modern China-derived hybrids are appropriate)

"Pteragonis" is very similar to R. sericea pteracantha, with the same ornate red thorns, but a larger flower in a pale butter yellow hue. It makes a very interesting specimen shrub with virtues that go far beyond that of an ordinary Spring blooming species hybrid.
