does anyone know this shrub

any chance of a pic ?

yes i hope to get pic very soon

Sempervivum is the only plant I can think of that has "cobwebby" stuff all over it, but I'm not sure that's what you're thinking of - google it, its called sempervivum arachnoideum

thanks bamboo googled it and thats iti think thanks again

I googles it too
very interesting

Hmmmmm, except that the flowers of Sempervivum don't last for one day only. Yes Kev, a picture sounds like it's needed here.

I wonder if you are maybe thinking of Helianthemum? Some do have slighly woolly/hairy leaves and have flowers with petals that drop quickly after a day or so and are quickly replaced by more. Some types do have flowers that match your description too.
