Purplish/red shrub rose? Grows to 3-4ft height.

Hi Kath, this is a new 1 from David Austin, so never grown it, grows to a height of 4ft or more, spread 3ft or more, depending on pruning regime.
David Austin are selling it for 16. 50, but don't know what their delivery charge is, Crocus are selling it for 13.25, delivery charge is 4.50, but no matter how much you buy it's the same charge.
Looks a very nice red, Derek.

Just checked Derek and it's beautiful.

If you're looking for something a bit bigger try Riene des Violettes - more purple than red, gets up to about 5ft, so a bit more height to turn into a standard.
