Autumn Joy stonecrop—Hylotelephium telephium 'Herbstfreude' (‘Autumn Joy’)—is a popular upright variety of stonecrop, also known as sedum. It is a hybrid plant created by crossing a species of sedum (Sedum telephium) with a species of ice plant (Hylotelephium spectabile). The resulting plant features gray-green, rounded, succulent-like leaves. And it blooms in the late summer to fall with tiny, pink, star-shaped flowers that grow in clusters roughly 3 to 6 inches across on top of the plant’s stems. After they bloom, the flowers gradually change in color to a deep rose and then rust before they die when cold fall temperatures arrive. Autumn Joy stonecrop has a moderate growth rate and is best planted in the spring after the threat of frost has passed but before the hot summer temperatures kick in.
