One of my favourite spring time flowers is Geralton Wax. They are the perfect drought tolerant plant, I don't think this bush has been watered since last summer and it is absolutely magnificent this year.
I have two bushes. One (the lighter pink flowers) we bought at the Native Plant Sale which is held I think once a year. The way they are cultivated they are virtually guaranteed to out grow plants that you buy in a garden shop. Within 12 months I had a large bush covered in flowers. The other bush is still tiny and it was just bought in a standard pot and is only 50cm high and there is only 6 months difference in planting. The original is about 1.5 m all round and has been butchered every year after flowering. Now it is just a pink ball.
Might have to head back to the sale this year (if I haven't missed it) and get some more they just look fabulous.
