Sorry to disappoint...mine was planted in the field and grew somewhat but didn't do much. I expect the variegation to be gone in the spring. Check back next July!

I've planted it in the field and we'll see how it grows. The problem is that winter dieback may kill the variegated branch.
Any updates on them? C:

Variegation from viral infection has a random expression, with little relation to leaf venation, as opposed to genetic variegation, which tends to follow veins, ribs, etc., per folks who know more than me. A plant pathologist can make an educated guess from a photo and UC Davis, Washington State University and other plant clinics offer plant sample diagnostic services for confirmation. I've posted a now-tested disease-free variegated rugosa in the past and as a seed parent, it passes variegation to a small percentage of seedlings, only from canes showing variegation, so Stefen's hypothosis reflects my experience. Canes from runners are invariably green. Talking to Star Roses, public perception of variegation in roses might be a problem, as some would assume disease.

Is this seedling yours? It’s incredible! I’d love to perhaps get a cutting if it’s a stable sport down the line?

It was a good question! Thank you and you're welcome!

I was just curious and thanks Kim!

They don't appear to, Rob. The buds were pale pink as the flowers normally are. If the petals had also demonstrated variegation, I'm positive it would have been mentioned. Both of them are pure "plant geeks" while one is far more focused on roses. But both are incredibly observant and possess knowledge I can only aspire to! A very neat occurrence they pointed out during the visit was this sporting of Autumn Damask to Quatre Saisons Blanc Mousseux on the same cane. That was fun! I had never seen it before.

Kim,

Very cool. Do you know whether or not the flowers on that cane were also expressing variegation?

If it is an aphid spread virus, it appears that the probability is significant.

Dumb question, but if it's a seedling from parents that don't present similar signs of "virus" and if the seedling has never been grafted, isn't the probability of such ridiculously slim? *If* it were a virus, is it conceivable that the carrier for the virus would *not* have exhibited such extreme variegation as to be noticed as well?

I was actually going to pose the question as to whether the origin of the variegation was obligatorily a concern, but then did a little research and learned that the virus that caused e.g. the striping in tulips a couple centuries ago *was* in fact ultimately fatal to the plants. I hadn't recalled that it actually killed the striped cultivars expressing the virus' traits.

The variegation runs through the CANES as well as the foliage. I'm waiting for an email to tell me the identity and age of the plant.

An email has arrived, identifying the variegated plant as Chloris, a plant received from Barbara Worl, the lady who discovered Grandmother's Hat and brought it to the world's attention. She shared the plant with them in 1989. This is the first anomaly it has expressed in all the time it's grown in the garden.

Kim, how does your friend know that the rose is not virused?

That rose of your friend's Kim is very beautiful!

The variegated seedlings from this spring posted above for the most part don't look too healthy. The variegation seems to be less pronounced than before and lead to the leaves being smaller and kind of mottled and off color. I shared some for virus testing and it'll be interesting if something is found.

Anyways, today as I was looking at a plant of my Pretty PollyTM Pink there was a variegated sport! One branch went all yellow and there was a number of leaves that were part green and part yellow/white. It seems like an unstable variegation, unfortunately. It was a fun surprise to see this today.

It is a bit slower growing and weaker and it is a single soft pink.

I love the look of the Fracis Meilland sport! With the edges being more consistently white, I wonder if it is a periclinal chimera with just the outermost layer of the growing point being mutated to not produce chlorophyll.

I suspect mutated chloroplasts may be the reason for the attached variegated seedling on the plant stand right now. There are a handful all from the same mom. It has R. wichurana as a great grandmother. Maybe that R. wichurana is related to the variegated R. wichurana on the market or is just prone to the same kind of mutation??


Any updates on this seedling? :)
