Crassulaceae is the botanical name of Sedum (Medium), also known as Stonecrops. It is a perennial plant consisting of fleshy leaves and star-shaped flowers. It can survive in extreme conditions and thus suitable for planting on green roofs.
Next, comes how can you propagate Sedums? Crawling sedums are very easy to propagate. You need to just cut some of the stems of Sedums. Allocate them on top of the potting soil. For tall sedums propagation, you can do it via division or via stem cuttings as well. Remember, Sedum stem cuttings must be 3 to 5 inches in height taking care of the leaves which should be sacked from the bottom inch. The best time when you can get positive results for planting sedum is the spring season.
