We carry both low groundcover sedum varieties and upright sedum varieties.
Sedum, or Stonecrop, are evergreen plants with thick succulent leaves. Clusters or rosettes of starry flowers appear during the summer.
Use for ground cover, containers, borders, and rock gardens. They are deer resistant and drought-tolerant, while being very popular to bees and butterflies!
