Marland Beauty is a cultivar that's quite commonly available in Australia. I have seen at least 3-4 succulent nurseries sell it.
Here is a great photo from Let Love Grow Online Nursery which is one of the great online sources for buying Sempervivums in Australia.
It shows all the seasonal changes of the cultivar. This is one of the reasons why I like this seller. They are very good about this sort of stuff.
I would imagine this cultivar has been around for at least 5plus years.
Bloodshot on the other hand I never heard of before. Here is a screenshot of the Ebay listing
Normally I would have bought it just to see it in the flesh as it were but currently the seller did not have other plants I was interested in so I didn't want to pay postage for a single plant.
And thank you
@PaleoTemp for putting the link up earlier
