Sedum is part of the stonecrop genus and has become well-known throughout the green roof community, as it is well-suited for the harsh conditions of a rooftop. Its characteristics include:

• Very drought tolerant – Some species can survive an entire month without substantial rainfall
• Very hardy – Easily adapts to changing environments due to its genetic makeup and high number of chromosomes
• Many species thrive in direct sunlight
• Becomes dormant in the winter and turns a beautiful deep red – This keeps the rooftop looking natural and fresh all year round
• Sedum promotes biodiversity by attracting butterflies, bumblebees and hummingbirds
