Money Plants and other Lunaria members such as Moonwort can be grown outdoors from seed by sowing at a depth of 3 mm. This can be done either in autumn or just before the last frost of spring. Money plants can be grown in either sunny or partially shaded parts of the garden that has good soil.

Caring for Money Plants, Honesty - Lunaria

Money plants and Honesty are pretty easy to look after; they will self seed so if you do not require more Lunaria plants in the garden the following year, remove the plants before they shed seed. It is necessary to mulch the plants at the beginning of winter if you are planning to grow Lunaria as a biennial.
