How to Grow Mignonette and other Reseda Plants in the Garden

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 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 apart, and larger Reseda members about 30 cm 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 and light.

Caring for Mignonette - Reseda

Once growing it is important to pinch back the tips of juvenile Mignonette plants as this will encourage branching and lead to more Reseda flowers.
