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. I had a packet of seeds which I soaked in hot water overnight. I planted some in a large pot so that the roots would have room to grow downwards. I put the rest of the seeds straight into the garden in a bed which was raised high with a dry stone wall facing north-east in full sun. The seeds were planted around the top edge of the wall, thus giving the plants well good drainage.
