When we purchased our home 12 years ago, it had well established gardens. They weren't particularly my style but they were OK and didn't look too bad. Basically there was a garden of different coloured Grasses at the front and a cactus garden at the back. The cactus garden is now more of a rockery which basically means I have added other plants in amongst the cacti. Sometimes those cacti can look very pretty:
One of the native grasses in the front just about took over the whole area. As it produced prickly spikes all the time, it wasn't very endearing, so last year a kind friend spent a very long time removing it for me. I was thankful I didn't have to pay him commercial rates as it was a huge job! The whole garden has been replanted and is much more my style, though I have kept all the small grasses and the rather attractive purple fountain grass.
Hibiscuses love our sub tropical climate and daughter number 2 has been very generous with sharing cuttings of some of hers. Even though the flowers only last a day, they add a bright spot of colour in the garden or on the dinner table.
