Rosa bracteata X (rugosa x palustris)

Took these pictures while out collecting hips.
Three of the four siblings showing the mounding and spreading growth habit - but keep in mind these haven't really regained full size yet.

 Here's a blurry close-up of the thorns on one.

 Here's the foliage on one that shows a strong influence from palustris.

 The open-pollinated hip harvest - see they really aren't sterile!

 And here are the vicious prickles that I've spent the last two days removing from my finger tips because I stupidly insisted on picking them bare-handed. I wised up and used a leather glove and steak knife to extract the seeds. There was typically only one seed per hip, but quite a few had none and a couple even had 2, 3 or 4. Definitely not super-fertile, but certainly not a dead end either! Maybe next year I might even give hand-pollination a try again.
