Sedum is one of the most popular perennials grown in American gardens because it is very easy to grow and hardy in most areas of the country. It should be sited in average to poor soil that is well-drained. Plants grown in rich soil tend to be lanky and open. Most varieties should be grown in full sun to light shade. The lower growing types, however, will survive in partial shade. Divide sedum every 3-4 years to maintain its compact growth habit. Older plants tend to split in the center if they have not been divided. Pinching the taller varieties back by half in early summer will also help prevent them from splitting. This plant is not usually bothered by pests or diseases. The seed heads of the taller varieties provide excellent winter interest and food for birds. Remove them in spring when the new growth begins to show.
