Speedwell is also more commonly referred to as veronica. They are hardy, herbaceous perennials that can grow as tall as 36 inches, depending on the variety. Speedwell is usually grown as decorative border plants, or as accents in rock gardens. The spear-like flowers of speedwell come in a wide assortment of colors, including light to dark blue, pink, white and rose. Plant speedwell in full sun and provide it with well-draining soil.
Place seed raising mix into planting cells until the soil is about 1/2 inch from the top of the rim. Tamp down the soil in the planting cells, using a small block of wood, or the back of the spoon. Make sure the seed raising mix has been well firmed down.
Place the planting cells into a container that can hold about 1 to 2 inches of water. An irrigation tray, or similar container will do. Sprinkle 3 or 4 of the Speedwell seeds across the surface of the soil in the planting cells. Push the speedwell seeds firmly into the soil using the back of a spoon. Refrain from covering the speedwell seeds with soil.
Mist the surface of the soil in the planting cells, until you are sure it has been well moistened down. Cover the planting cells with a sheet of glass, or clear plastic wrap.
Place the tray of planting cells in a dark location and where the temperature will remain between 70 and 75 degrees F. Keep the soil in the planting cells on the moist side, but never allow them to become drippy wet. Add water to the bottom of the tray as required. Germination of speedwell seeds typically begins in 3 to 4 weeks, but can begin in up to 3 months.
Remove the sheet of glass, or plastic wrap, from the growing containers as soon as you see the speedwell seedlings emerge. Transplant the speedwell seedlings when they have developed a strong root system and are about 3 to 4 inches tall.
Planting Speedwell Seedlings
Dig holes for your speedwell seedlings that are slightly wider and deeper (about 2 inches) than each of the planting cells. Space each hole 6 to 12 inches apart for smaller varieties, and for larger varieties, 15 to 20 inches apart.
Remove a speedwell seedling from a cell by pushing up from the base of the cell. Set a speedwell seedling in a previously dug hole. Make sure it's sitting at the same level in the soil as it was in the planting cell.
Fill up the hole with soil, packing it down as you go. Water each of the speedwell seedlings thoroughly.
