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.


  1. Paul, what are the chance of smooching some pollen from pteragonis...

  2. Don,
    I will begin collecting pollen today. :-)

  3. Do you already have plants blooming outside?

  4. Thanks. The thorns seem to be intermediate between a 'normal' prickle and the pteracanthous one. My guess is this is due to it being heterozygous and there is only one way to find out.

    BTW, I have a seedling of Sericea pollen on Golden Angel. So far it's just showing spin-like prickles but it does look like being a hybrid.

    i am completely taken by a rose being prized as much for the thorn as for the flower. And what a beautiful specimen portrait!
