Direct sow seeds in early fall, planting them just below the surface of the soil. For spring planting, mix the seeds with moist sand and store in the refrigerator for 60 days before planting; keep the soil lightly moist until germination. This seed can also be started indoors 6-8 weeks before planting in the spring. Plant two seeds in each peat pot and keep the soil moist until germination. Since these plants dislike having their roots disturbed, plant them outdoors as soon as possible after the last chance of frost.
Water seedlings until they become established. Mature plants also appreciate occasional watering, though they also tolerate drought. This plant usually produces only foliage in its first year, coming to its full height and blooming in the second. The flowers of this plant attract bees and butterflies. This plant usually self-sows in good growing conditions.
These ornamental seed pods make long-lasting additions to dried flower arrangements. After the pods have completely dried on the plant, cut the stems and hang them upside down in a dry place until the entire stem is dry. If desired, carefully remove the outer layer of the seed pods to reveal the silvery inner layer.
After the seed pods have dried on the plant, remove them and spread them out to dry completely. Open the pods to remove the flat seeds. Store the seeds in a cool, dry place.
Seed - cooked:
A pungent flavor, they are used as a mustard substitute. The pungency of mustard develops when cold water is added to the ground-up seed - an enzyme (myrosin) acts on a glycoside (sinigrin) to produce a sulphur compound. The reaction takes 10 - 15 minutes. Mixing with hot water or vinegar, or adding salt, inhibits the enzyme and produces a mild bitter mustard.

Root - raw:
Used before the plant produces flowers.
A fatty acid obtained from the seeds has been used in the treatment of multiple sclerosis.

Silver dollar will cozy up to just about any other plant but you might be quite delighted pairing them with various tulips, Forget-Me-Not, Foxglove, and Hakone Grass. If you want to attract more beneficial insects and creatures to your garden, add an herb patch.
