trellis climbers help req

im putting up some trellis at the back of my garden, that gets very sunny.
i need to know what will grow in dryish conditions, something hardy that
will give me good coverage, not soil picky if thats the right word...
fastish growing..to block out an unsightly view i have, anything with flowers.

 

Welcome @fender62 (from another Welsh gardener!) If you could keep the roots cool (eg a big stone over the top of them), then clematis montana or viticella hybrids would give masses of flower in the sun. See here for details:
Clematis montana var. rubens 'Tetrarose' (M) | clematis 'Tetrarose'/RHS Gardening

 

Just a couple of suggestions....Trachelospermum jasminoides (evergreen, small scented flowers) and Campsis 'Mme Galen' (deciduous climber with big, showy pinkish/orange flowers). The viticella clematis do well in most situations, too.
