    Katnippy, I must be going senile, I have absolutely no recollection of recommending James Austin or Ivor’s Rose!! I do have IR, another newbie (had a mega rose buying splurge) but it can get much bigger and wider than stated so not sure if that would suit there. I have allocated it a really big space. 

    Delbard (Chartreuse de Parme, Belle de Jour) have a good reputation for both health and fragrance, but again, health depends on your conditions. My blackspot pressures are fairly high due to summer heat and humidity, but their La Rose de Molinard is clean for me and has a really intense grapefruit fragrance. The downside is that because the blooms are so full, it does suffer some petal damage in the rain. Yet another thing to consider!

    You probably have a lot of discussions going on within the New Rose Season thread 🙂

    I thought I had made up my mind to take a chance on Sandringham and I think @edhelka posted some nice photos on a thread but I’m now tempted by IR as it’s a darker pink. I’m wondering if I let it be for a few years then prune it to keep to size... My sunny patch is about 3.5m wide so I was planning a couple of medium size roses at the back plus a hydrangea paniculata (leftover from going OTT on plant purchases during the first lockdown whilst I tried to distract myself!). It’s a shame IR has no/little scent but I’m leaning more towards healthy - do you find it is in your climate? Beales describes it as almost evergreen - have you had it over winter? 

    My east facing garden can get quite damp in places when there’s heavy rain in winter/spring and the odd shrub has black spot. Do you have any tips for treating it? I’d like to avoid Rose Clear if I can. I have one shrub in a pot which has suffered badly every winter but then recovers and looks lovely every summer though I’m thinking of chucking it for the sake of all the other plants - don’t want the garden riddled with it.

    I would just strip that rose over winter. 

    I would never use Rose Clear because it has insecticide, if you have to use something, Fungus Clear is better.

    Clearly I’m having a senior moment then 😊 Have a look at this re Ivor’s Rose, helpmefind is a great resource, mainly US contributors, it’s known as Flamenco Rosita there. It seems pretty bomb-proof, but as it’s new for me this year, I couldn’t give you any personal experience yet. The trick is to take note of reviews from people that have a similar climate to you:

    I just practice good hygiene to keep on top of BS - pruning to open up the centre and allow good air circulation, regularly picking off any diseased leaves or those fallen on the ground and mulching to try and suppress the over-wintering spores. I also defoliate when pruning in the dormant season as leaves hanging on also carry it forward to the next season. I did try one foliar treatment of natural yellow sulphur early this year, but I’m not really a sprayer.

    If you want disease resistance, go for Ivor's Rose and not Sandringham or PAoK.
    In my garden almost everything gets blackspot and the worst offenders defoliate quite early, so better to ask people from eastern or southern England, their experience is much more relevant to you than mine. I think @Tack has Sandringham if I remember correctly.

    Excellent, thanks @Omori, I checked it out and much prefer it. 

    Luckily the winter sick shrub is not a rose but an Escallonia. I stripped it last spring and it grew back and looked great all summer but it’s at it again. Thought it was Escallonia leaf spot but it may be black spot as a nearby shrub looks a little suspect unless it’s just general all round dampness I have to contend with. The photinias get it a little and bounce back but I don’t want to risk any roses I buy. The healthier ones the better.

    Thanks @Nollie and @edhelka for your advice - Ivor’s Rose it is then. Today I ordered The Poet’s Wife, Lady of Shalott and James L.Austin - looking forward to summer.
  • I’ve only just read your remark about the bed being 3.5m wide... the problem I’ve always had with David Austin roses is that they reach the advertised size in two years, but then they don’t stop there. If each of your roses manages 1.5m in width, you’ll be hard put to it to fit in a hydrangea as well... perennials might be better.

    Thanks @Cambridgerose12 the hydrangea is meant to reach 1.2 x 1.2m and I should have mentioned LoS will now probably go in the front garden as, by the sounds of it, it likes plenty of room. There is some leeway with the width in the back border...it will just mean a little less patio area for us and if needs be, the hydrangea will go elsewhere as the roses are the priority.
