Wow! Yes, Joe. Lemon Fizz *is* working well for you! LOL. Nice! I have had crossing LF with Campfire on my to-do list as well, if and when I get Campfire. (Great minds think alike?) Now I'm more enthusiastic about the potential. I wasn't sure if LF would largely throw singles, or if doubles were a decent probability

That looks like a very striking plant in its own rights, regardless, and has two strong parents. I wonder if it would be a stronger grower as a grafted plant? But I'm also assuming that is still a relatively young seedling? ...so...

What folks consider appropriately vigorous in your neck of the woods frequently makes for monstrous garden hogs in the south. The trend, I think, was for roses for smaller gardens last decade. If the health is on par with its parent's, I think it might be worth having someone trial in a warmer climate. (Someone with more extensive, and more secure realty than I have to offer, alas. I wasn't hinting! I can't offer a secure enough setting for such.)

Rob, for years I've been curious about the whole Swany / alba meidiland / sempervirens x Marthe Carron line of roses from Meilland (one sibling of which is the parent of Bonica). Have you worked with them much, and have you managed to get anything other than whites and pale pinks out of them? I'm not sure how much cold hardiness sempervirens offers, but as a synstylae hybrid, Swany offspring could probably be integrated with the setigera lines I'm trying to create as well. (David Z, have you tried that route?)

Philip,

I had Bonica for several years and found it to be a great seed parent but did not have my luck with disease resistance in F1. Mostly light pinks. I did get one orange/pink using All a Twitter as the pollen parent. Swany was new for me last season so I don't know what I'll get out of it yet. I wasn't looking at Swany for cold hardiness but rather for increased petal count, excellent repeat bloom and disease resistance, when matched to any of the Canadian roses that I'm using, and the resulting F1 crossed back to another Canadian rose.

Bonica was a gorgeous landscape shrub out here...for a while, until it succumbed to crown gall. All the Meilland landscape series out here are as addicted to gall as the Flower Carpets are. Whatever the common denominator is, it LOVES gall!

yesterday potted up some seedlings from golden celebration. Pollen parents were williams double yellow and also martin frobisher.
Also a couple from some Theresa Bugnet seedlings that I am testing as parents.

Today will be potting up some from Theresa Bugnet x Mary Rose.

Also have more than a dozen seedlings up from a rose I don't have a name for (I call it the North 40 rose for where I purchased it), I may post a picture this summer and see if you can help identify it. It took pollen really well and is germinating well so far. We'll see how the genetics pass on.

Nice crosses Duane. I like what I see on HMF for Golden Celebration. How is disease resistance for you on that one?

I have had no problems with disease in the two places I have grown it (western montana & northcentral Washington). But then I have not had many issues with health in the English Roses I have grown, just not much pressure I guess. Until this year: I purchased Charlotte from a nursery, it appeared great when I got it but ended up covered in mildew shortly thereafter (which I have not had problems with) which it promptly passed to several others. I'll see if it returns this spring. I guess some disease pressure would be helpful in culling seedlings anyway.

Which diseases do you have in your location?

Oh yeah, I'm having better germination than I expected from Golden Celebration, considering what I have read: not sure what that is due to. Looking forward to seeing what comes of it.

Duane,

I have high pressure here for black spot and cercospora and you are right, some disease pressure is helpful in the culling process. Hopefully you can post some pics of any Golden Celebration seedlings at some point. I like the Therese Bugnet x Mary Rose cross as well. I could see very full blooms from that cross.

Full blooms is what I am hoping for: not for future breeding, but for cutting for on the kitchen table. (although future breeding is always in the mind.) Love the fragrance of Theresa Bugnet, but it seems variable in strength: of course I don't think Mary Rose will help in that regard, let alone staying power with the petals.

Forgot to add another cross germinating well is Rugelda x Lady of Megginch. Interested to see what comes of it. Early season in pots with no other pollen, so used Lady of Megginch & The Squire (all I had). I'm more prepared for this coming season.

Although Rugelda does get some leaf spot here, I really like its color, blooms and foliage. It can pass on disease resistance. Good luck with your crosses!

Germination today from a cross that I'm excited about :

Yellow Brick Road x Frontenac

The plan was some yellow color, disease resistance, double petal count, prolific bloom, good repeat and hopefully, Z3b hardiness. Thinking ahead, this F1 might be good to cross with Campfire.

That sounds like a great cross! Look forward to hearing what the results are. Hopefully it will be useful in moving forward. I'm thinking that will be the challenge: recognizing the potential in a seedling, even if it wasn't what you were looking for right off the bat.

Be interesting to see its cold hardiness.

Duane,

Hopefully I’ll get something I can move forward with and to post something here about as well.

For me, the best hipsetter/germinator this year has been Oso Easy Italian Ice: a healthy, small but spready shrub with beautiful semi-double orange-yellow flowers.

Sheer Elegance also is germinating well.

The germination disappointment of the year has been Pinkerbelle--a beautiful, healthy, fragrant hybrid tea with great hipset... but zero germination.

In all cases, I've been crossing those females with a mixed pollen consisting of micro pot roses--Gigi Parade and Karina Parade and two unnamed ones from Por La Mar.

Anyone used Brick House? It sounds aligned with my goal of compact healthy reds but it's sold out at all the nurseries I've checked.

Out of curiosity, and not that it is a guarantee of viability, did you try any of the Pinkerbelle seeds in a water flotation test?

I thought I had posted this but apparently it's not there. Oso Easy Italian Ice generated lots of hipset and germination. Sheer Elegance too. The year's big disappointment: Pinkerbelle. It's a beautiful, fragrant, disease-resistant hybrid tea that set seed beautifully but...no germination.

No, I didn't do the sinker test. The seeds certainly looked normal.

No, I didn't do the sinker test. The seeds certainly looked and felt normal.

You could try extracting a few embryos to see what they look like and if they will turn green for you. I guess it depends on the size of your seeds how easy this would be to do.

Is there an easy way to extract embyros? I was under the impression it was difficult and time-consuming---This way https://www.researchgate.net/publicatio ... bunda_rose
or at minimum, this way: https://www.youtube.com/watch?v=_85GT8swiU8. I'm too lazy for such, especially when I've not heard that Pinkerbelle seeds produce wonderful babies.
