It would be very helpful if growers would post the range of petals counts (counting all petaloids) for their Harison's Yellow.

My plants are in the yard of my 120 year old farmhouse. I know they have been growing here since at least 1930. I am uploading two pictures shortly.

Also of interest: I have had 2 or 3 blossoms on this plant in early November two years.

37 petals and petaloids. First bloom opened 29 April at latitude 38° 22' N. Scent is sweet (not linseed oil upon first opening). Petals are distinctly darker yellow at the base where they connect to the receptacle. This plant from High Country Roses has bristles on the receptacle.

Hello Cass,
I am looking for a characteristic to tell the difference between Harison's Yellow' and 'Persian Yellow'. As far as I can see, one difference is the petal count" Harison's Yellow' - 20-25 petals; and 'Persian Yellow' - 40 petals. Is this an accurate assumption?
Do the red streaks that appear on 'Persian Yellow' appear on 'Harison's Yellow'?
Are there any other visible and specific differences

Hi, Patricia. I don't grow Persian Yellow, but I've been following a discussion among Peter Harris, Margit Showalter and David Zlasak about the different versions of Harison's Yellow sold in North America. To the best of my knowledge, the real Harison's Yellow has bristles on the receptacle, whereas the imposter does not. Young canes of Harison's Yellow are armed with both weak and firm prickles.

The key characters noted on Persian Yellow are the red streak on some petals and a very double, globular to cupped flower form that doesn't open flat to reveal its stamens. The color is a more saturated golden yellow. Harison's Yellow is bright but closer to the color of a lemon. We also know that an imposter was in commerce was in commerce as Persian Yellow in the USA in the 1950's.

Persian Yellow is nicely documented on HMF. I wish someone would post a photo showing the hip color.

That is most helpful Cass. Thanks.
I only grow 'Harison's Yellow' and will look forward to next spring with interest and peer at its receptacle.

Patricia, I just posted a photo of the hips, which are not yet completely ripe. They show the deep maroon color, persistent sepals, prickly surface of the hip itself, and prickles on the peduncle.

I'll post another of the interesting orangish color of the peduncle.

Wow! Fred Flintstone could have hung that up in his cave and used it to dong thingo-sauruses on the head. Seriously though - again most helpful. Thanks Cass. I've just been out to have a look at my plant and there are only remnants of what might have been hips. I'll check in late summer. (I need a computer calendar which comes up as soon as I turn the computer on and which says "Do this today, Do that also. - and this and this and this....")

WHen I click on the tiny photo of a rose, I do not get an enlargement, but just a new page with photo ID and date and a message that photos are copyrighted and all rights reserved. The thumbnails are TOO SMALL to see. I have Firefox on an Apple computer.

Several people have reported a similar problem but we are unable to replicate it here in the support department. If you would be so kind as to work with us we're sure we can sort it out. Can you send us the url for a plant photo you are unable to view ? We would be very grateful to have your assistance with this - it has to be something simple.

I can partly replicate this problem on Firefox on my Macs. Under the Firefox Preferences menu, please select Content. The second option, "Load images automatically," must be checked. If "Load images automatically" is disabled, images do not load. Under the PHOTOS tab, images appear as a vertical line. When I click on that line, the image page loads so I can see the comments, but the image itself is represented only by the photo ID: xxxxx and a vertical line instead of an image. This happens on two Mac operating systems:
Mac OS 10.4.11, Firefox 3.0.10 and
Mac OS 10.5.5, Firefox 3.0.10

If you use the Safari browser, you should see the images on HMF, because you cannot prevent images from loading on Safari.

"I have been told by other experts that the Harison Yellow will not get seeds from pollen of native roses. Yet I am reasonably sure that one seedling here is an Harisonii x R. acicularis cross. I suppose such cases could be called amateurs luck."
