The scientific name of honesty is lunaria annua. It also is known as money plant, dollar plant and moonwort. This is due to the silver dollar-shaped fruit that it produces. Honesty is a biennial with beautiful purple flowers. It will add interest to your garden throughout the spring and summer. It blossoms in April through May, and by mid-summer the blossoms give way to sprays of fruit. The fruit or seed pods are thin and silvery, and when mature they are translucent. Honesty is native to Southeastern Europe and Western Asia and can be found in gardens throughout the United States. It grows to a height of two to three feet, and the sprays of fruit often are used in dried flower arrangements.
Cut off any remaining fruit sprays (if you haven't already cut them off for drying) after the first hard frost. Place the fruit sprays to the side.
Cut back the plant stems from two to four inches from the ground. Place the dead plant material in your compost bin.
Rub the dried silver dollar-size seed pods (that you placed to the side) in the plant bed to disperse the seeds. This will produce additional plants next year. Dispose of the dead plant material in your compost bin.
Cover the plant bed with mulch. Use leaves, hay, straw or evergreen boughs.
Remove the mulch in early spring to allow the new growth to appear. Once the new growth appears, add mulch (cedar, pine, stone, etc.) to the plant bed to keep the moisture in and to keep the weeds down.
