The information here refers to the biennial plant that is confusingly called Lunaria annua. It also goes by the common names Honesty, Moonwort, Judas' Penny, Satin Flower, Money Plant, and Silver Dollars.
Season & Zone
Exposure: Full sun to partial shade
Zone: Hardy in 3-10
Direct sow in early spring, when there is still some risk of frost—mid to late March on the coast. Or sow in the fall if winters are mild in your area.
Sow seeds a couple of millimeters (1/8") deep, and space plants 3045cm (12-18") apart.
Mulch well before the first winter. Transplanting does not work well with this variety. Plant in any reasonably fertile soil, and pull up plants after flowering if you want to prevent self-sowing. This variety dies back after its decorative seed pods form.
