Hear hear, patience is a virtue in apparently dead plants. My local shop keeps 'dead' plants for me to look at, and sells them to me at ridiculous prices (they think it is ridiculous because they are selling me a dead plant, and I think it ridiculous because I have had good plants for next to nothing!). E.g. my now large and beautiful corkscrew hazel cost me 49p., ditto several other things. Seems like a winner either way - and teaches patience.
Talking of which, i have a 'James Stirling' whipcord hebe, which is about 9 - 10 years old. It is a lovely shade of gold, and has become a pretty big plant. This year, for the first time, it has covered itself with little white starry flowers! Who would have thought!
