What Are True Leaves?
When a seed first emerges from the soil, or potting mixture, it has a set of two leaves called cotyledons. The cotyledons are actually a part of the seed, and act as a food source for the sprouting seedling. At this time the seedling does not conduct photosynthesis. It gets all its food and nutrition from the cotyledons.
As the seedling becomes stronger and healthier, it will begin to form two more leaves that look very different from the cotyledons. The true leaves will look more like what the plant’s leaves look like when mature. Once the true leaves are present, the plant is now actively photosynthesizing. Eventually the cotyledons will wither and fall off as the true leaves take over the job of feeding the plant.

Take cuttings from a healthy sedum plant and remove the bottom few leaves. Place in a clear container with water and some soil and put near a window. Once it roots, plant it in a pot of soil and water it well. Cuttings can also be planted right in the ground as long as they are in a well drained area. Sedum love to be in water in the beginning, but once a healthy plant starts, they can be planted anywhere. The more sun they get, the more color they have!
