[...this pink one is stunning! Well done! I love it!]

This is one of my favorites. Even though it goes through many color changes, it's beautiful all year long.

[...It changes colour? That's even more fascinating!]

I think most sempervivum do - especially those with pink or red in them. This one goes from pink to purple to almost red sometimes. Some of them are red in the spring and fall, but green in summer. But they can act differently in different areas, climates, temperatures, etc.

Here are some examples of some nice color changes during a year:
Jeanne d' Arc: Hen and Chicks (Sempervivum 'Jeanne d'Arc')
Purple Passion: Hen and Chicks (Sempervivum 'Purple Passion')

[...wow, I had no idea! Thank you so very much! Learn something new everyday on here!]

The more we find out about these plants, the more fascinating they are.

I love that shade of pink

It's a stand-out in the garden. Has a very nice form too.
