Gather multiple potted plants to create the splendor of an in-ground border in a spot where gardening is otherwise impossible. Using containers, you can fill a space with beautiful color and texture that rivals earthbound planting beds. - My Cool Garden
Place bulbs shoulder to shoulder across the surface of the soil, leaving no space between them. Then top off with more potting soil so the bulbs are just slightly below the surface. Water each container thoroughly, and finish with a layer of mulch.
Love Lily of the Valley! Also makes a wonderful ground cover perennial. The very fragrant flowers appear in abundance in April and May. They are ideal for growing in wild or woodland gardens or use for ground cover in a damp shaded border.
