Sunday morning, I walked out to get the paper and saw this sparkling sedum. The clear nodules within the plant are drops of dew. In person, they looked like pearls of water. This is the same Autumn Joy sedum I wrote about last fall. What I love about sedum is its seasonal changes and its complex architecture. What other plant has such an eye-catching shape when it first emerges in the spring? This is the first of several faces and colors the sedum will show between now and next fall. Sedum are related to succulents, which would explain the cactus look, and their versatility and hardiness have led to their use as plants for green roofs.
