Sweet Spirit

This almost could have been a reply in the recent thread asking about hips generating excitement. But posting as new thread to avoid thread-jacking. I’m kind of excited about Sweet Spirit. I have two plants that I keep in pots and store inside for the winter. It is a Double KO descendant, which migh...

Re: All A'Twitter x Yatkan

Having worked so hard to incorporate R. virginiana and R. carolina into my seedlings, I'm probably screwed in terms of creating a rose that's healthy nationwide. Thank you for the help in identifying downy mildew! It's probably around, but not super prevalent. We've had a somewhat easy year so far f...

Re: All A'Twitter x Yatkan

I don't seem to have downy mildew here, although I'm not sure I know what it looks like. I still have AATYAK, now growing in a pot in the greenhouse. I love the foliage. I actually have a few seedlings of it this year, but didn't make the effort to pollinate with it this year. We'll see if those see...

Re: Problem with rabbits

Liquid Fence might work. It is a spray that you spray right on the roses. We use it around here, mostly for deer.

Re: Funky Yellow & Seedlings

So I have this seedling which is Funky Yellow x Icecap (or vice versa). Icecap hasn't really done all that well here, but it really blooms heavily and the blossoms last on the plant a long time. This seedling seems to have gotten the funky character from Funky Yellow. Not sure what to call it...poin...

Funky Yellow & Seedlings

I have a seedling of 1048 that I call Funky Yellow, because the blossoms are often kind of odd in a variable way. It's decently hardy and healthy and reblooms so I've kept it and used it a little in breeding. See pics. Anyways, to avoid confusion I'll post pics of a seedling of Funky Yellow in a rep...

Re: Saving pollen if a seed parent isn't quite ready

Just for kicks I took a look at some of the pollen from one of last year's vials under the microscope. The pollen grains were not withered...they were plump and round. But they were white/clear rather than golden. I wonder if they were viable? Does anyone know if a pollen grain can retain its shape ...

Re: Saving pollen if a seed parent isn't quite ready

I put my dried anthers into an extra-fine tea strainer sitting on top of a small funnel going into a glass vial that can be capped and is airtight. Then I put a few blue desiccant beads into the vial and cap it tightly. The pollen can then be put in the fridge for a day or in the freezer for maybe u...

Re: pictures Martin Frobisher Seedling

The plants of rugosa roses that we buy are own-root, which tells me they must be rootable...not sure if there is any difference in rootability and technique from the popular modern roses. It might be that, even if it is diploid, your seedling will have enough genetic diversity to avoid the sterility...

Re: pictures Martin Frobisher Seedling

Love it, Duane! It's so nice to get a blossom that looks like it should be super fragrant...that actually is super fragrant. I hope it repeats and is rock solid hardy. Some thoughts as to the possible parentage: I crossed Métis with Catherine Guelda last year. Two pink roses who each have Therese Bu...

Re: hardiest reblooming diploid?

Riku, I used RDXS a bit quite a few years ago but gave up because it didn't seem to pass on rebloom very often if at all, and the plant itself got some fairly ugly spotting. I had one odd reblooming seedling that came from (R. carolina x RDxS) x Commander Gillette, which is not a cross that should h...

Re: Yellowing of rose leaves.

It sounds like your water might be the problem. You could use citric acid to acidify it prior to using it, if possible, or use rain water. There are pH testing strips that you can order on eBay...the more detailed the better from 4.0 to 9.0. It is fun to check your tap water's pH and then add citric...

Re: Video tour including Metis and Bella Nitida

I pretty much have missed my window to pollinate the taller, hardier, apparent Metis this year, unfortunately. A combination of being busy and burnt out and not having enough reblooming pollen available. Riku, your Metis sounds like the first one I had, which also died back last winter. My seedlings...

Re: Air-layering pods

Ads for these have been showing up in my facebook feed. As always, I try not to think about why.

I would like to try these or any air-layering on Hazeldean, Prairie Peace, and Harison's Yellow.
