Good fungi, bad fungi?

I don't know if this has been addressed before, but has anyone ever used mycorrhizae in their seedling mix in an effort to stave off the bad fungi? I don't know if my understanding of such has any merit, but I have had seedlings push through fuzzy media in the past without any noticeable problems. I...

Re: Misfit seedlings, anyone?

Well, the seedling with the long petioles is acting in a manner that so far reminds me of descriptions of "foolish seedling disease" caused by the Gibberella fungus. I'm thinking it has a hormonal issue. Internodal lengths are quite long, as are the petioles. I hope it won't self-destruct as I'm cur...

Re: purple stamens

Beautiful, Joe. I like those contrasting centers, but the dark stamens in particular seem to draw me.
In view of my attraction to dark centers, I'm really not sure why I have yet to try any hulthemias. (Though I have always presumed they would resent my humidity.)

Misfit seedlings, anyone?

A watched seedling never grows and blooms, so while I patiently bide my time, I had thought it might be interesting to share images of seedlings that just don't do as expected when germinating. *sigh* Unfortunately, my macro photography skills are evidently not up to the task, so pardon verbal descr...

Re: purple stamens

Kim, it occurred to me to search purple stamens in this forum (duh) and came across a brief exchange b/w you and Jim on the subject of his hulthemias. I likewise followed the link to Jim's "baby Dainty Bess" (No idea why I had forgotten Dainty Bess beforehand.) Also found a mention of David's Carefr...

Re: purple stamens

Basye's Purple, and Paul Barden's 'Purple Folio-Chief' were the two foliolosa descendants I was thinking of when I alluded to such. I don't know if there are others. Looking again now, I see that Ann Endt does *not* have purple stamens, as I thought I had recalled. In fact, I am finding surprisingly...

purple stamens

Came across a Tantau cultivar, "Strandperle Norderney" https://www.rosen-tantau.com/en/rose-strandperle-amrum/ an apparent rugosa hybrid which reminds of some foliolosa descendants. I was trying to think of other purple-stamened roses (Burgundy Iceberg, perhaps the moyesii "Geranium", and i was goin...

Re: Petite Knock Out Rose - AVOID

I generally object to the notion of utility patents. Any sort of legislation that renders the offspring of organisms that can and do procreate without human interaction "illegal", or that relegates them the intellectual property of the patent holder, is IMHO fundamentally flawed. In this particular ...

Re: Help identifying this rose

Very unusual to my eye. I typical tend to think of mutable roses as having a yellow that fades even as UV light darkens the red (did we decide to call that photochromic?), or as having a red that "fades" to a purple or grey, but this appears to have a more stable yellow as the pink fades, possibly w...

Re: Worms eating seeds

BTW, Joe, the wasp you mentioned is probably the Rose Seed Chalcid. It's very tiny, and the larvae are tiny fat grub-like things. I collected rugosa hips in Maine years ago, and saw ity-bitty pinholes in a bunch of seeds when I finally got around to processing several years later. Discarded the obvi...

Re: Petite Knock Out Rose - AVOID

"What if they licensed me to breed with it if I released the resulting roses through them? Would I suddenly feel better about it?" I kind of doubt it. Their patent means that they would hold all the cards in any negotiations, if indeed they even felt any reason to negotiate. Ball Horticultural, and ...

Re: Petite Knock Out Rose - AVOID

I've long thought the patent laws surrounding utility patents seem highly problematic for something that reproduces sexually (as have a very large number of smarter folks than I) and I *have* to believe the courts will eventually be forced to change those laws.

Re: Worms eating seeds

In your baggies? That's odd. I generally think of fungus gnat larvae (of which I've had more than my share) as being slightly more translucent and a bit less, I'ma say, lanceolate(?) on the end. I might lean towards nematodes, but I'm not overly familiar with such. Regardless, I don't know that it w...

Jim, I don't know if you would have any access to such, but evidently Star *is* currently trialing Kordes' 'See you in Purple' to decide whether to release in the USA. In principal, it should have a very high resistance to BS and Mildew based on Kordes' rating for the plant. I haven't yet grown any ...

Re: Rosa Helenae Hybrida Off Spring Success in NAmerican Cold Zones?es?

Can't contribute any observations for you, but I am of the mind that there a good many species in the Synstyllae section that have not been adequately mined for their potential. Helenae is one I have wondered about for over a decade, based on my readings about the species at the time. (Never acquire...

Re: Is every rose seed completely unique?

Point taken. "Rarely noticeable" was poorly worded and not my meaning. It was intended solely to contrast with my follow up comments. I meant only to acknowledge that, to an untrained eye, the variations often might not be remarkable. The offspring are "identical" only inasmuch as they are the same ...

Re: Is every rose seed completely unique?

A classic example of siblings that differ would be Mister Lincoln, Papa Meilland, and Oklahoma, all of which were independently created by different breeders around the same time with similar goals using the exact same cross (Chrysler Imperial x Charles Mallerin). The plants are similar, but differ,...

Re: What is the easiest and hardest steps in rose breeding?

Patience is the hardest part for me. I'm surprised nobody else said that. I can get into the zen of most of the other processes while reflecting on the potential outcomes, but waiting to see if any of my efforts came to fruition is rough. (Spoiler alert: They generally don't.) I've been dabbling in ...
