Im not sure of the name of this sempervivum, but its one of the largest i have in my collection.
It takes a few seasons, but grows to around 15cm wide taking on gorgeous red edges through its growing season
autumn / winter through this period i have them out in all the elements, and they thrive.
Planting in shallow bowls with good drainage works really well.
i like to shade my sempervivums through the warm weather and minimal water as they are dormant.
