How to grow:
Diascia seeds should be sown outdoors after the last frost of spring. Once sown the seed should be lightly covered. Diascia prefers to grow in a sunny area of the garden that has good drainage. They should be sown at about 15cm to 30cm apart, depending on whether it is a spreading species or not. Twinspur should ideally be grown in a soil that is rich in humus. 
If you prefer to grow Twinspur first indoors, then the process should take place about 7 weeks before the plants are transplanted back into the garden following the final frost of spring. Diascia species take about two to four weeks to germinate at at temperature of 15 degrees centigrade.
