Hi Jen, we've got a breeze block wall too and I did think of painting it, but decided against it because it's holey, you need an awful lot of paint to cover it well, which works out expensive and it's a lot of hard work.
We screwed diamond patterned trellis on battens and then planted various roses, star jasmine, escallonia, and ceanthos on it, south-east facing, and clay soil. Initially expensive, but won't have to do it again hopefully.
The wall is about 4 ft high (which has got the diamond trellis on it with another fence on top. (The neighbour's garden is at a higher level than ours).
