Rose standard rootstock ID

I had a standard that sadly died. The rootstock seemed alive still so I planted it. It's now got flowers and much prettier than I expected! Anyone got any idea what variety it might be?

    Lots more information required, including better pictures.. close ups, scent?..  I can't really see that one properly.. I'm not sure which way up it is..

    Details of where rose was obtained, imported?..  name of original variety, which part of the rootstock did you use, interstem or the roots in the ground.. they are sometimes different roses..

    edited to add..
    Ok.. it might be Rosa indica 'Alba'.. which is used as an understock in parts of Europe..
    Characterised by 5 leaflets.. rounded buds, white, double blooms.. mid green foliage..

    Thanks for helping!

    No fragrance to speak of. If there is anything there I'd say it's more fruity than my others which are supposed to be old rose.


    It was a David Austin standard, Bonica originally.

    Seems to be growing from the interstem maybe?

    Ok, R. indica 'Alba' is the only double flowered rootstock I know of that's in use, but it's used more in southern Europe - warmer climates .. I had wondered if the rose was imported.

    As you bought it off David Austin you would be best to ask them really.. I cannot help further, but I'm not sure if they graft all the Standards they offer, so they may have got this from elsewhere...
    Rootstocks, including the interstem,  in common usage for the UK and northern Europe,  tend to be dog rose variations, which have single flowers..

    Best of luck with it..

    edit, just to emphasise how difficult it is to identify from a few blooms..
    this is the common and popular climbing 'Iceberg' rose which looks much like yours.
    I would find it odd if they used this as the interstem, and the foliage looks different but who knows these days, as it's mostly thornless..

    Great, thanks for your help!
    I'll ask David Austin and see.

    Apparently the rootstock is Laxa. They are checking on the interstem and will get back to me.
  • MarlorenaMarlorena Posts: 8,705
    Yes, the rootstock in the ground is nearly always Laxa, but those blooms and foliage are not from that, as it has a 5 petalled single flower, so something else is going on there..

    They've emailed and said Pfander

    @jonathan.cole
    I thought they might... yes R.canina 'Pfanders' is commonly used as interstem on Standards.. the problem is, it's a single flowered rose of the dog rose type and the foliage is quite different..

    ..do you think that looks like yours?  I don't..

    Not in the slightest!
    Oh well, mystery rose it is!
