Thank you all for your feedback and suggestions, happy to receive any more if there are any lurkers out there with views to share.
Yorkie - I didn’t have a particular colour in mind until you raised the question, but as I lost my Mum recently I’m guessing Yellow as it was her favourite colour. I’m not really bothered about scent, but as you suggest repeat flowering would be a bonus for the pollinators and you get to enjoy the colour and flowers longer.
Compostqueen - Not really into the fruits and hips, John on our Allotment suggested brambles and blackberries but I’m in the process of purging the * from the plot and I really don’t want a source of them up against the wall to spread into the plot – I think I will be fighting them for some time as it is. And I’ve been a Gooseberry in the past but I’m not fond of Gooseberries to eat.
MumofStig– As above re fruit and – blackberries – Thanks for the link to the RHS I like the idea of the “glorious mess” above the areas shown on my photograph and keeping the sides and tops of the arches pruned I will take a look at “Beales” as suggested, and have put “Albertine” on the list. Until now I didn’t realise there are so many different types of rose!
catllar – Thanks for the suggestion of “Mermaid” and now thanks to Yorkie I’m looking at “Yellow” flowers this appears to fit the bill, unless there are any others that are faster growers, looking at the RHS web site it says Albertine – 5m and Mermaid – 6m but the ultimate Heights and Spreads are the same, so I’m a little confused about that. And the Hardy Rating is H3 better than H4 ?
With 2 metres of growth per season I’m guessing you mean per “Year” or 4 seasons in a year would means it will be 8 metres growth in a year – nearly as good as those brambles
So at the moment it’s looking like
Mermaid
is the front runner
