The triplet lily is a perennial flower that is native to western North America. It is also referred to as the cluster-lily. It is a small flower that only grows 4 to 6 inches high. The flowers bloom in spring and are purple in color. The tiny flowers are very popular in Europe and are often used as a container plant. The triplet lily prefers full to partial sun and well-drained soils.
Choose a location in your garden that will receive plenty of sunlight and well-drained soil. Mix 2 to 3 inches of organic material such as peat moss or ground bark to improve the soil if the area tends to have puddles.
Dig a hole that is approximately 4 inches deep and 2 inches wide for each flower. The holes should be 4 inches apart.
Place the triplet lily into the hole and backfill with native soil that you dug from the holes. If you are planting the bulbs, the top part of the bulb, with the point, should be facing upwards.
Water the soil generously with 2 to 3 inches of water immediately after planting. The flowers will begin to grow within a few weeks after planting. Allow the foliage to die down and do not remove the dead stems. This will provide nutrition for the new plants in the spring.
