Re: first roses of the year

And here it is in the ideal stage. Candidly, I'm shocked that the third to bloom seedling from my first breeding efforts in 20 years (and I had none so nice 20 years ago) is so pretty, so I thought I'd share these pix of it with you in hopes of inspiring you to perhaps try the cross: Oso Easy Italia...

tissue culture

When one has a seedling he'd like to have tested in multiple locations, does one make cuttings (e.g., 1-node, 3-node) or is tissue culture a viable option? If so, is there some lab that does that?

Re: great foliage

Yes, I think that's a holy grail--foliage so attractive, you're happy to have it even when out of bloom.

Re: first roses of the year

I do not believe that coloration was sun-induced: 1. It bloomed in early April--not much sun 2. The days during its bloom were not that sunny or hot. 3. Believe it or not, it's now been over a week and the color has remained stable and the flower still looks good---Alas, just 11 petals. We'll see if...

Re: first roses of the year

Indeed, it is the first bloom on any of my 300+ seedlings this year. I'm not sure the pollen parent is Gigi Parade. You see, I used mixed pollen---Red Sunblaze, an unnamed red pot plant, and Gigi. But with the coloration ofthe flower, I'm assuming it's Gigi. Of course, I could be wrong. Re phototrop...

first roses of the year

Here attached is my first bloom of the year--a micro-mini. The cross is OsoEasy Italian Ice x Gigi Parade. One pic is a close-up of the (slow-opening) bloom and one of the plant.

Re: Prediction of the Diplocarpon rosae secretome reveals candidate genes for effectors and virulence factors

I don't understand the article but can't help but think with the large,growing, and more resistant forms of fungus plaguing roses (not to mention insects such as Japanese beetles) that as people get busier and more environmentally conscious, the only way roses will remain commercially viable is crea...

Re: First germination of the winter

Whoa, 5% bleach, well, I guess I don't really know but intuitively it seems like that would kill them. Let the soil get slightly dry between waterings. As dry as possible without risk of the plants wilting. Oh, Clorox is already diluted to 5%. I meant diluting THAT: 1 part Clorox to 19 parts water,...

Re: First germination of the winter

Update on Pinkerbelle. Perhaps because of its thick pericarp (Did I leave it on the bush until fully orange--perhaps thus too long), while it had zero germination at the time the others were germinating, now, a few weeks later, I'm getting a few seedlings, so perhaps this exciting HT isn't useless a...

Re: First germination of the winter

Rob, thanks. Reviewing the protocols reminded me of my core characteristic--obsession with time-effectiveness and so, I've decided to let the damn Pinkerbelle seeds just sit in their potting-soil, sunny home, and, if perhaps because of their unusually thick pericarp, they decide to emerge a month or...

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

Re: First germination of the winter

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.

Re: Anybody using any of the old HT fav's of the 20th c.?

Sheer Elegance, for my money, the most beautiful hybrid-tea flower ever, also has good hipset and germination. I haven't used it before. I'm looking forward to evaluating the seedlings. In the San Francisco Bay Area, it's been rather healthy for me: no mildew, maybe a bit of blackspot, but rust at t...

Re: First germination of the winter

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...

Re: Variegated roses?

A couple new Poulsen Parade roses are striped flowers with gorgeous form. Gigi Parade (red and white stripe) and Tijana Parade (pink and white stripe.) I get mine at Trader Joe's and they may be available at Home Depot or your local supermarket.
