I'm really hopeless at gardening. Have recently finished clearing our garden which involved a lot of hacking- it was wild, tbh- and now we have a patchy garden with nothing much in it.
Weather wise, it's year round warm, very little rain. In winter, it will be mid 20s usually, in summer, it will be mid to high 30s, up to maybe 40°C or so. There's not much rain and we sometimes have water restrictions, so the plant would have to be hardy. No real shade at all.
I'm also a completely terrible gardener. I really struggle at keeping anything alive (which is a plant, I mean)
and all I really want is a pretty/nice looking plant which can do well in our garden and can survive me 
In the front, we have Californian lilac. I've been looking stuff up and have been thinking along the lines of Black-eyed Susans, flowers like that?
I'm clueless about plants, so need ideas?
