Re: hardiest reblooming diploid?

Thanks to Karl and Riku for your suggestions. Karl, I'm not sure I want to use a rugosa like Hansa for this purpose because of the potential for delayed remontancy, ie. a lack of juvenile bloom, which makes screening for a low percentage of rebloomers a much more difficult process. Riku, it seems li...

hardiest reblooming diploid?

Does anyone have ideas for the hardiest non-rugosa diploid that is fully reblooming? My best guess at the moment is Darlow's Enigma. Because I got some rebloomers out of Metis x Catherine Guelda, I'm trying to figure out what pollen to put on Metis this season. Maybe the Ole, Lena, and Sven roses fr...

Re: Alternate source for repeat bloom

a tangential aside: Prairie Joy, which reblooms but doesn't produce a high percentage of reblooming seedlings, has produced two seedlings that really shouldn't rebloom but seem to. One is PJ x my local native rose, and the other is PJ x (R. carolina x R. centifolia). So could Prairie Joy have some s...

Metis x Catherine Guelda

I was psyched to get good germination from Metis x Catherine Guelda. I was hoping that maybe a percentage of these would be juvenile bloomers. Hoping against hope, because it seemed like a lot of strikes against that happening. So I was really excited today to see four buds among the 100 or so very ...

Re: 'Commander Gillette' X "3/4 Native"

Philip - re: FOLIOCOM seedlings. Just a few. It appears pollen sterile, and is not super fertile as a seed parent. Might need longer seasons to ripen the hips properly. There was an interesting FOLIOCOM x Miracle on the Hudson seedling with lots of small, pure red blossoms, but it was not a keeper o...

Re: using vinegar to lower soil pH

Powdered citric acid works well, too. You have to get some pH test strips to help you get in the ballpark. For my water here, it's about 1 teaspoon citric acid powder to three or four gallons of water.

Re: 'Commander Gillette' X "3/4 Native"

Murphy's law - single pink! It's fun that you're reinforcing the species blood. My reblooming POITECOM (Belle Poitevine x Commander Gilette) has terrible pollen and rarely sets hips, but last fall I found a few and I'm psyched to have four germinations. I'm hoping that these will be tetraploid selfs...

Re: Extra seeds

You know, Philip, exactly what you said about the garden center. I'm worried for my employees. People are so excited to get out of the house. Narrow aisles. I'm too busy to direct traffic and print signs. If someone gets sick I will forever question if I could have done more, but for now I'm forced ...

Extra seeds

Anybody in the USA short on seeds to germinate? My garden center business is nuts this year and I won’t have time to seed all of my seeds. I have some cool species crosses and various others with a lean towards cold hardiness. Many are quite sprouted and would need some intensive care. I can’t promi...

Germination, stratification methods report

I've posted extensively about my somewhat impulsive and varied stratification methods and typically poor germination, so I thought I'd give a brief report on what's happening for me this spring. I'm behind most of you other Northern Hemispherians this year in my transplanting. Normally I sow my seed...

Re: purple stamens

First pic (off topic) - no anthers. I think Ann Endt or Rugosa #3 x R. carolina.

Second pic, a rose I call Black Anther. Ann Endt x (Bulls Eye x R. virginiana). Actually set some hips, which was cool.

Re: Germination of crosses I'm excited about

Good crosses, Rob! Thanks for breeding for cold hardiness. Why haven't I grown Quadra? Larry, the seedlings of A & B that have juvenile & repeat bloom are precious indeed. I know they do occur, as I have one Henry Hudson x A&B and two All the Rage x A & B that repeat. As David has mentioned, there m...

Re: Help identifying this rose

I contacted the gift shop at Gothia Towers in Gothenburg. They were kind enough to contact their supplier and heard back quickly that the rose is called ‘Magnolia.’

Looking on HMF, it seems to be Magnolia Kordana.

Re: Help identifying this rose

It's very interesting when you look closely at that picture. It seems like the flowers are actually fading from pink to yellow, which is quite novel. I would have agreed with the hypothesis that it was multiple cuttings in the same pot, but several of the buds show both colors.

Re: Worms eating seeds

I found the microscope. It was fascinating to look at the worms under the scope. Very smooth, with no sign of segmenting or the black head of fungus gnat larvae. Look very much like the Enchytraeus buchholzi mentioned above. Most nematode photos seem more microscopic. I wish I could have taken a pic...

Wow, thanks everyone for the replies! I can't find my darn pocket microscope, the use of which seems like a logical next step. Maybe I can capture a photo through it that will help us learn more. But the scope is likely buried under one of my piles of miscellaneous crap...the question is which pile?...

Re: When to expect Rugelda F1 first blooms

Duane, I think Above & Beyond is one good path forward to combine yellow and hardy. Keep in mind it is not a reblooming rose and produces fewer than 1 in 6 reblooming seedlings when crossed with rebloomers. Therefore you have to grow larger quantities of seedlings from these crosses and cull to keep...
