Funny you happened along meriad, I almost asked in my post whether you had any ideas
I had a lovely hebe out there which didn't like it at all; it got really, really leggy; long wavy branches and few flowers. Cutting it right back didn't help, so I moved it to the back garden where it's now looking lovely after a couple of years.
There is a potentilla out there too, which survives although not brilliantly
The hydrangea, which was a bargain, has done really well but I don't particularly want another one - I don't even like them that much lol, but knew they do well here as most gardens have them
Have a feeling the dead one might have been a different hebe too...the lesson is to not spend much as it's not likely to survive!
I might wait till Saturday and go see the shrub man at the market, he knows what he's talking about and is good value
