Sedum is a large genus of flowering plants in the Crassulaceae family, commonly known as stonecrops. Their natural drought tolerance and ability to grow in harsh environments have made them ideal plants for the green roof industry.
The characteristics of Sedum are as follows:
- Drought tolerant – the plants have fleshy water storing leaves and most varieties can survive up to a month with minimal rainfall
- Many species thrive in direct sunlight and high heat environments
- Most species thrive in porous media with low organic content making them ideal plants for most green roof media recipes
- Common species used in roof applications become dormant in the winter, maintain their leaves and turn a deep red or purple colour keeping the rooftop looking alive and colourful all year round
- Flowering Sedum promotes biodiversity by attracting butterflies, bumblebees and hummingbirds
