The timing of the sowing of Scabiosa depends on their nature. Annuals are usually sown after the last frost, perennials may be sown at the start of spring or autumn.
Scabious seeds should be lightly covered once sown, and spaced at about 30 to 40 cm (12 to 16 inches) apart.
They like to grow in sunny areas that have good drainage.
Ideally the soil that Scabious grows in should be humus rich, slightly alkaline (pH 7 to 8), and moist.
The germination of Scabiosa seeds usually takes about two weeks, and can be done indoors at a temperature of 20 to 25 degrees (68 to 77°F).
If growing indoors first, then sow annuals five weeks in advance. Sow perennials about 10 weeks in advance.
Transplant annual Scabiosa following the last frost of spring. Put out perennial varieties in late autumn, or before the last frost of spring.
