Rosa sericea subsp. omeiensis f. pteracantha

[Jupiter]

Does anyone know anything about this rose? I just discovered it and I'd love to grow it. I wonder if it can be propagated by seed?

[Maggi Young]

 I had a look to see iof Bjornar had it on his list -   http://trillium.no/   - sadly he doesn't.

Thanks Maggi. If anyone has one or knows someone who has one grab some hips for me!

It is in this year's SRGC seed list if you intend ordering and have not already done so.

Well done , Roma - I hadn't thought to look!  Nearly 5500 taxa and I never thought to look! How  embarrassing.

I have grown R. sericea from seed (Chris Chadwell) several times and the seed germinate easily. I have not had seed of pteracantha though but suppose it is not more difficult.

Rosa sericea from seed: flower and prickles. Unfortunately not as ornamental as f pteracantha has although the young shoots have more colour.

Thanks Roma, you know I didn't realise that the seed exchange was open! I'm working through it now... one word.. overwhelming!

Hoy, thanks but it's the red thorns I'm intrigued with. The flowers are a bonus.

Interesting.. I have grown this from cuttings... The hips my produce hybrids.
The flowers produce pinkier flowers in the shade and that soft yellow in full sun. I will look to see if there's hips or I can send hardwood cuttings in winter..
Check out mistydowns rose nursery they do species and mail order.

Interesting that this should pop up on the forum today. I just noticed a post about it on the Rare Plant Enthusiasts page on FB.I hope to add it to our landscape sometime in the near future. Those red thorns might look striking alongside the green daggers of Citrus trifoliata (formerly Poncirus).

I've grown Rosa sericea subsp. omeiensis from seed.  That many years ago (2006), I assume it was the pteracantha form, due to the little knowledge of the subject I had.  This is what grew for me.  It still has never flowered for me in my climate USDA zone 4a) with severe winter dieback and winter rabbit predation.

That's what I thought!
If you try seed you can't be sure what you get and it takes some years before the potential of the plant shows.
I think cuttings are a safer and quicker way to get what you want.

Yes cuttings would be great but our quarantine restrictions make it hard to get live plant material into the country. It's possible they'd come through. I'm willing to pay postage and take a gamble on having it confiscated if someone knows where there is one with good thorns.

I have a nice picture of the thorns but sadly, not the plant itself. I know of several plants at least, in NZ but not of any available to buy. This picture was taken at Lake Tekapo in 2005 at an Iris Society Convention.

Why do I have it as Rosa omiensis? Has it had a name change or have I just made a faux-pas?

(A bit later) - Now I get it, I just left out the first bit. But what a mouthful!

[Karaba]

I have already sown some seeds collected on R. sericea subsp. omeiensis f. pteracantha (from garden and open pollinated) and I have got few R. sericea subsp. omeiensis but no f. pteracantha. I did't get many seedlings so, I don't know the percentage of f. pteracantha. For sure, cuttings is safer.
