Watered fairly regularly for the first year, then rain only. Slow release fertiliser applied at planting and perhaps a couple of times since. Now 70 cm high by 70 cm across. No pest problems and looks healthy. Germinates in sunny areas in sandy soils after heavy rain, then flowers and sets seed quickly to use available moisture.
Seed germinates best if soaked overnight in hot water.
Alternatively can nick in the back of the hard seed coat. Sow where is to grow as root system grows so fast that transplanting a problem. At planting drench soil with general purpose fungicide to prevent seedlings damping off. Plant needs moisture to start and regular watering to maintain. Position with at least half a day's sun.
