Hi all - Please may I have some help for a neighbour who is a gardening novice and has recently lost his wife to cancer. She loved natives but hasn't been well enough to garden for some years. He wants to plant a small area of land in her memory and doesn't know where to start. The land, which is in Sydney and frost free (on the Cooks River), is flat, enclosed by a brick wall which has proper drainage, and is at the base of a small (7 metres) sandstone cliff which is north facing. From time to time it gets major storm runoff but this doesn't lie.

He wants a list of appropriate and, preferably, showy plants, easy to locate at nurseries, to get him started....shrubs, groundcovers (weeds will be a problem, the land is not easily accessed from the house, which is at the top of the cliff) and a tree which will reach the height of the cliff but no higher (to hide a sewer line down the rock but not obscure the view which is gorgeous).

Can you people help, please? The more input, the better.
