Autumn Joy, planted side by side with daylilies presents a colorful contrast of leaf tones and adds color to the flower bed as day lilies' blooms diminish. Autumn Joy sedum grows 3 to 4 feet tall.
Aeonium arboreum is dense perennial succulent that reaches heights of 3 to 4 feet. The brilliant green leaves are edged in red. The red accent edging is especially intense when the plant is located in full sun. The dramatic deep red tones of the leaves provide a striking contrast to the lighter green foliage of daylilies.
