Hi Viswalingham. It looks as if you still have the green cane tie around the bottom of your Rebecca holding all the stems still together. It might help if you cut that gently off and spread your stems outwards like a fan to separate them - the stems may be strangling each other. Would also be a good idea if you have some kind of wire attached horizontally to your fence so that the stems can be attached to so that it knows it has somewhere to go, reach out for and attach or be gently tied to.
As the others have said, you need to have something in front of it at ground level to keep the bottom few inches of the stems in the shade as they come out of the ground. It hates heat at the roots. And a good couple of cans of water might pep it up. It may be that the stems are too close to each other and winding around each other so I'd get the green plastic cane tie off and spread em out - but they need something to climb up and attach to. Once they reach the top of the cane there's nowhere for them to go.
The leaves are green and there are nice buds so I don't think it has wilt. I'm wondering if it is just strangling itself with all the stems together. Also wondering about the gravel around it - could dust from the gravel be leaching into the soil.
I bought Rebecca last year so mine is still young. I have it attached to quite a thin section of trellis nailed to the wall facing west. It's in a pot though and the pot is also inside an old wooden box which I used to use to stand plants on next to the back door. So the roots and first few inches of stem are kept cool and dark. Last year it was in full sun and hated it - but it was scarlet red. This year it has sun for half of the day and is more a claret colour. I give the pot a can of water every three or four days - depending on the weather. I don't want it sitting soaked, just kept moist. And until it bloomed I fed it just with liquid feed every couple of weeks. It's only it's second year so not a huge amount of blooms and the first are going over now. But I see some tiny budlets coming here and there so may get more.
Be brave. I made a mess planting mine last year in full sun and only had two flowers and that was it. I'd never done clematis before - and sometimes courage pays dividends. I'm sure you will solve your problem. Go for it.
