Growing roses from seeds

I have a pair of nice, perfumed roses that are getting quite old now.
This season one of them produced a nice fruit containing 8 seeds.
It is a light pink variety and I also obtained some seeds from a white perfumed rose.
Last time I did this was with my grandfather and I was still a little kid LOL

The common way of multiplying your roses is by grafting them onto a fresh stem of some wild or low quality roses.
The reason for this is quite simple: A "manufacturered rose" is usually designed to look pretty and show certain other features, but not be a strong plant.
When using seeds it all comes down to how strong the original mother rose was, not the stock it was crafted on.
In some cases you end up with a little bush rose in other cases with something that grows so high that the stem will break in strong winds.
But for the lucky few cases that do work good you are paid off with a beautiful new rose.

For next couple of weeks the seeds will stay in the fridge to aid germination but if it works out I will take pics of the progress and document it all in an Instructable - but it will be about a year to finnish as roses grow slow from seeds.
If I don't forget it again I will also show how to graft one rose onto another to get a bush with different varieties in one.

How are you doing? I am a breeder of both roses and rose-roostocks, so very curious...

I planted the remaining seeds in little pots and wait for something to happen.
After the last failure I left them in an open container in the fridge.
Sitting between some wet paper towels.
Now I have read that not all roses that produce seeds can be used as some create seeds that never germinate.
But I won't give up, if in doubt I will start again with the next seeds coming in a few months.

Funny thing is that if you keep those pots somewhat moist the seeds may eventually germinate! Have seen this in 'forgotten' batches. Where did you sow them in? We use coco peat which seems to give the best results...

Lol
Coco peat here as well, I use nothing else for my seeds and cuttings.
Nice and sterile, plus it holds the moisture very good.
The pots are in a shaded place and get a moisture check every time I feed the chickens, so hopefully something will happen.
If not there is always the option of cuttings but really would like some fresh stock from seeds.

Be aware that you will not get the original rose back, but more likely a different new variety per seed. Only very few roses (canina varieties etc. ) will produce more or less reliably from seed...

Thanks, that is what was aiming for anyway as would like t see what actually comes out of the seeds.
The mother plants are full of color and perfume, so hopefully one of the features will make it through.

Interesting...
Do you have an idea of the hybridization?

I'm guessing they're a hybrid tea rose, but they might be a bit different depending on the age of the roses and where they came from.
The hybrid type can help tell you if you're going to be getting hardy plants from the seeds.
Hybrids that use Rosa species not native to the area aren't as likely to be well adapted.

The roses were grafted in AU about 12 years ago.
AFAIK the old stock of a wild rose used to cater for the new ones.
Took your reply to check on the seeds and have to say I am a bit disappointed.
a few started to develop mould while the others turned to a yellow color.
Neither of this happened to me last year so I have to assume something went wrong or the seeds are no good.
Will leave the yellow ones a few weeks longer though.

I'm looking forward to reading about your germination process I hope you are successful!

Me too, I know it needs several weeks to happen and there is a high chance nothing happens at all.
But I was lucky in the past so I hope all goes well around August / September so I can contnue the topic.
