Busy Lizzy (Impatiens walleriana) are also sometimes called jewel weed, impatiens and touch-me-not. They are one of the most commonly grown and beloved of all annual flowering plants. Busy Lizzy are profusely blooming plants and grow to form dense, 8- to 24-inch high mounds with an equal spread. Due to the minute size of busy Lizzy seeds, when started outside, it's best to use planting cells and then transplant the seedlings directly into your flower garden.
Prepare the planting cells by thoroughly washing them in a solution of 10 parts water and one part bleach. Set the planting cells in the sunshine to dry. Pour in a seed-raising mix to fill the planting cells full to within 1/4 inch from the top of the rim. Use the bottom of a glass or the back side of a spoon to compress the soil in each of the planting cells.
Pour water into each of the cells to moisten down the seed starting mix. Place the planting cells into a watering tray. You can purchase a watering tray from your local plant nursery or garden center.
Transfer the tray of planting cells to a warm location in your garden, but not where it's going to receive any direct sunlight. A location that can provide between eight and 10 hours of filtered light a day is sufficient. For best germination, the temperature needs to remain consistently between 68 and 75 degrees F.
Place the busy Lizzy seeds on top of the soil in each of the planting cells. Try to plant three to four busy Lizzy seeds in each individual cell. Press the seeds into the soil, firmly using a small block of wood, or a table knife. Because busy Lizzy seeds are tiny, you might want to try using a pair of tweezers to pick the seeds up.
Cover the tray of planting cells with clear plastic wrap. Check on the tray every other day to make sure the soil in the planting cells is remaining moist. Add water to the watering tray as needed.
Loosen the plastic wrap as soon as you see the busy Lizzy seedlings emerge. Germination will take between 14 and 21 days, depending on growing conditions. Thin down the busy Lizzy seedlings in the planting cells when they each have one set of leaves. Cut the spindlier seedlings off at the base of the stem to leave the two hardiest busy Lizzy seedling in each planting cell.
Transplant the busy Lizzy seedlings directly into a partially shaded location in your flower garden when they have grown to about 2 to 3 inches tall.
