Answer: Alyssum and Forget-Me-Nots are both early spring flowering annuals. If you cut back the spent flowers, they usually produce a second flush of bloom. But, if you allow the flowers to stay on the plants, they'll develop seeds which will grow into new plants the following spring.
You can sow seeds for these plants in early March. Other plants for you to consider are lobelia and pansies - they like shady conditions, too.
