Re: Freedom Gardens is a source for rare roses

Very interesting information! I'l definitely going to have to look into this a bit more. THanks!

Re: I'm new here, so I'd like to say hi!

John, kudos to you for your organization system. I consistently underperform in the area of recordkeeping, but have made some valiant thrusts in that direction including creating a Filemaker Pro database, which remains unfinished. I actually was able to print out a roll of labels with bar codes rep...

Re: I'm new here, so I'd like to say hi!

Hi Josh, My wife and I are in our 3rd year hybridizing in the Seattle/Olympic area. Coming from a software / data science background I'm personally obsessed with the tracking and process optimization. We manage our rose database in Airtable and we have out DYMO label printer hooks up to a little Ra...

Re: How to know how many plants I need for breeding?

Off topic, but thought of it when you talk of stingy pollen producers. As I've mentioned in another thread, I highly recommend getting a pocket microscope. A friend gave me a 40X one that was about a 4" aluminum tube the diameter of a pen. That worked well. Use a black bottle cap or a folgers lid t...

Re: Can any give suggestions on these roses for breeding?

Hi Josh, I looked at your list, many of of the roses you chose I've tired from time to time. In my zone 3 climate. Tender roses are essentially expensive annuals. I'm lucky to get them survive 3 winters. Maybe it's something I have to learn to master yet. George Vancouver would offer a lot of winte...

Re: Can any give suggestions on these roses for breeding?

That was once my thinking as well, but I would suggest that what that means is you are ultimately selecting for roses that have been around and have been heavily mined for their genotypes, (Not that that is a bad thing -- Kordes has occasionally returned to seedlings of nearly a half century earlie...

Re: Can any give suggestions on these roses for breeding?

From experience, I would add Fourth of July and Altissimo to your seed parent list as both make copious self set hips and their seeds germinate like rye grass. That doesn't mean you can't also use them for pollen, but why limit your chances by missing out of a guaranteed germinator? That is really ...

Re: How to know how many plants I need for breeding?

Repeat pollination can increase the number of hips set, as well as the number of achenes per hip. That's a point I never considered. In China, I volunteered at a breeding program this spring, and they only pollinated roses once. However, in the RHA booklets (and elsewhere), many suggested pollinati...

Can any give suggestions on these roses for breeding?

I know I've been asking a lot of questions, but I appreciate everyone's answers so much! You've all be incredibly helpful. Next year, I've decided to focus on red (hopefully dark red/black, but I'm starting slightly broader using reds in general). In addition, I'd love to get a dark red striped rose...

Re: Itsy, bitsy, teeny, weeny

I love the idea of these micro mini roses! That's sad that they are as difficult to grow as you all say. Has there been much done breeding-wise with these super tiny miniatures?

Re: How to know how many plants I need for breeding?

Yes, roseseek and donald_vancouver, you're right. It's probably extremely difficult to give a good estimate. However, the concept that shrubs and floribundas seem to give more flowers is a useful one. The idea that hybrid teas give less is something I was definitely already thinking. I mean, they're...

As mentioned by others its going to vary by goals, location, available space, cost, etc.

The other variation is some roses produce 25+ seed a hip while others are lucky to produce 4.
Dang, you're totally right! This is so much more complicated than I first thought. I appreciate your input.

How to know how many plants I need for breeding?

Right now, I've created a list of all the crosses I'd like to make this coming spring. This is my first true year of breeding, so I don't actually have any of the plants yet. I'm planning to buy them soon so I have them somewhat established this year for next year. The problem I'm coming up against ...

Re: I'm new here, so I'd like to say hi!

Hey, Chuck! Those are all great questions. I'll go through them one at a time. What is the USDA climate zone? I am in 7b which I believe is similar to Washington D.C. (but that may not be right). What kind of soil you are working with? I'm not entirely sure what kind of soil we will have at our fiel...

Thanks, rosegeek, for those ideas! I'll definitely do a bit of research on those and see if I can get some of them.

Re: Seedling

Regarding Highwire Flyer, I want to note that the stunning rose on the cover page of the A.R.T.S. webpage (linked to in another post) is Highwire Flyer. I hope they can look half that good up here in Zone 3. I noticed another young seedling of the same cross that also has the metallic foliage. In o...

Re: Is this color prediction chart accurate (or useful)?

I'd say the chart is somewhat useful if you look at the percentages over 20% as there's obviously some general trend there that's occurred over a bunch of different roses. You just have accept that unexpected results can and do happen. As the chart shows though, if you're looking to maximise your r...

Josh, The early 19th century was a strange and exciting period. Trade with the far East was expanding, and many people would receive plants that they had no idea how to cultivate. Thousands of such plants were packed in boxes and delivered to nurseries with no return address of explanation of where...
