Sedum reflexum ‘Glaucum’

Reflexum vs rupestre – this is an ongoing debate that turns around the inflorescences and which way they face when the buds are produced.

However!

I’ve found in my Sedum journeys – both practical and literary that:

• the fine-leaved Sedum rupestre of Dillenius later was classified as Sedum reflexum, then reclassified by Linnaeus as Sedum rupestre var. reflexum named under Linnaeus so… they are.. the same?
• Petrosedum rupestre and Petrosedum forsterianum seem to be clearly derive from the same rupestre taxon but are systematically separated by taxonomists

It’s a bit of a wacky world.

I have found this illustration to be helpful – by Juan Luis Castillo in “Flora iberica”  of Castroviejo.

The plant can be seen on ‘green roofs’ or ‘green wall’ systems in Korea where plants are incorporated into the structure of the building, providing habitats for wildlife and innovative insulation solution for humans.
