Re: Newbie(ish) question

So its just preference, hurrah! I can safely go back to matching bloom colour to foilage colour.

Newbie(ish) question

So having read much of the past forum posts on here on the last 10 months, I haven't been able to solve a question even with the help of Professor Google, so..... Why the heavy preference to dark leaves? Is this just a basic plant biology thing where dark = more chlorophyll? Whats the problem (if th...

Re: Beginner Question, How to Streamline Germination & Plant

That would explain why my germinations typically happen in late March and through April (min daily temp is around 10c/50f). I thought it was the rainy period around that time (possibly helps)

For a species that is a weed in most of south east Australia its interesting how low the germination rate they had in the article.

There are two mini's (although hmf doesn't list any sources outside AU which only makes sense for one of them) that I like and both are fertile, maybe their lineage will be of use though https://www.helpmefind.com/rose/l.php?l=2.73569.3 https://www.helpmefind.com/rose/l.php?l=2.20720.0 Moon River is...

Re: Using Cultivars to Stabilize health Problems

Are you having a heat wave in your neck of the woods too, and are your rugosas tolerating such? Also being in Au and going through week long heatwaves I can say I have a fru dagmar hastrup and honestly it did better than most HT and floribunda, they got crispy and droppy, FDH doesnt seem phased at ...

Re: I don't know whether to be excited or frightened...

These are all within the first three weeks of planting. I harvested the seeds and didn't clean nor treat them with anything, just dumped them into separate small zip loc type bags and placed them in the dining room where they wouldn't be disturbed. I continued collecting and adding to the box until...

Re: thoughts on germination media

I always feel odd on this topic. I just use what I use in pots? 1:1:1 coconut coir, vermiculite, compost (or potting soil depending what i have bags of lying around). I dont stratify either, straight into the mix after being harvested. Im lazy and dont want to fuss eith them much. This approach for ...

Re: Rugosa roses disease resistance

Thnk you.
I agree that PM would have been probable, SSC gets covered in it for a while in spring here, have never seen any rose with it nearly as bad, most of its seedlings went through a noticeable PM period too.
Hopefully some of the new hulthemia being sold this year are better breders.

Re: Rugosa roses disease resistance

I can say this though when I used Fru Dagmar Hastrup normally the seedlings never looked good, occassionly one might find the vigour to bolt away but there was always PM problems. Yay something to look forward too....have made a lot of that cross this year... On a slight tangent, with the 46c/115f ...

Re: R.glauca help?

It's possible it could be self-incompatibility is going on there, but if there were other plants in bloom nearby that wouldn’t matter. There wasn't a lot of overlap if any, it bloomed early (but not as early as Golden Chersonese) there may have been a slight overlap with Lord Penzance towards the e...

R.glauca help?

So I got R.glauca this year. Many OP hips set, but most aborted, is there self incompatibility at play here? Anyone know? Also over on HMF there's photo's of it with green hips, mine maintained the purple/brown colour similar to it's canes and the few remaining hips are turning red now, approx 3 mon...

Re: A new rose rosette review from a scientist's viewpoint.

While RRV doesn't affect me (yet, hopefully never though...Australia) from the bits I keep reading only R. palustris and R. spinosissima appear to be consistently mentioned. Everything else is mixed in that some say X is resistant, while others report X has been infected. It may fall into the warnin...

Re: Project for large rose hip X R. Pimpinellifolia. Questio

The rugosa (there's also a rubiginosa hybrid) hybrid Magnifca's other parent was Ards Rover. Most Hybrid Perpetuals are tetraploid so Magnifica is probably triploid

http://www.helpmefind.com/rose/l.php?l=2.5558

Triploid doesn't necessarily mean sterile. There are fertile triploid roses out there.

Re: How long do we wait for first bloom?

I'm possibly too new to offer much with roses specifically (a decade or so with various other plants) but really it comes down to whatever the breeder is willing to accept and then skewing the population as a result. Sure when dealing with species or a few generations from you will need to be a litt...

Re: Why do some seedlings "close" at nite?

In many other plants it's about protecting sexual parts, the insects that pollinate them aren't out at night, frost damage (due to temp drop at night), rain, etc.

It's probably connected to that in some way.
