Would it look better without the half-round wooden fence posts covering it?
If you're going to plant climbers to cover it, you'll need to dig a decent sized border along it, and dig in some organic matter for your climbers to get their roots into.
Just planting something and leaving it surrounded by grass just doesn't work ... the grass competes with the plants for water and nutrition and you're unable to mulch and feed properly, and the danger of strimming the bark of the climber and causing fatal damage is very real.
Also beware of planting too close to the wall. Walls soak up moisture, and there is also an effect known as 'rain shadow' which means that quite a large area at the foot of a wall is shielded from rainfall by the wall, and plants really struggle because of drought. This is why it's important to make the border wide enough, so the plants can be planted away from the wall and sloped back towards it, and also increases the importance of digging in lots of organic material before planting, and mulching with it afterwards, so increasing the moisture retentive properties of the soil in that area.

Hope that doesn't sound too daunting, but if you get the preparation right it'll save time and money in the long run
