It is best to sow Mignonette (and other Reseda plants) successively if you want a long flowering season.
The seeds should be sown from the start of spring until the first half of summer. Sow out about 3 weeks apart.
The Mignonette seeds should be sown on the surface.
Ideally the Reseda plants should be grown in a partly shaded part of the garden that has a rich soil and a pH of 6 to 7.
The spacing of Reseda is species dependent, plant smaller varieties about 15 to 20 cm (6 to 8 inches) apart, and larger Reseda members about 30 cm (1 foot) apart.
You can also start Mignonette off indoors. They should take about one to three weeks to germinate, and require a temperature of 21 degrees centigrade (70°F) and light.
Once growing it is important to pinch back the tips of juvenile Mignonette plants. This will encourage branching and lead to more Reseda flowers.
