Lori, I know they aren't grown for the flowers, but I find them quite charming! They are putting on a good show here this year--most of my plants are still smallish, but I guess a lot of them reached maturity this year...
Rick--great colour especially on the April shots..nice big clumps, too..
A locally purchased S arachnoideum tomentosum.. when I bought this, I was sceptical about it being arach: the rosettes were large and open, and not that wooly--obviously grown in a greenhouse or some much milder climate (B.C.?) a couple years here they are small and tight as they should be...(more so in this overcrowded nursery pot.. I do find rosettes are much larger when first planted with lots of room.. no surprise, I guess..)

Very nice trough photo, Rick.

Cohan, you have a very nice tapestry of colours going there too.

You've got a lot of flowering going on this year, Cohan!  I also find the cobweb type hen and chicks to be variable, depending on the time of year and care.  If you notice, even though my April pic of S. arachnoideum 'Minus' and the blooming shot are different plants, the habits are typical for the time of season here.

Speaking of tapestry, here's some nice "quilt work" from early May.  You can easily pick out the two Sempervivum octopodes.

             

And a nice form of Sempervivum calcareum

Thanks, Lori-- they are a lot of fun, and don't mind this cold wet year at all :) Really need to get some division going in that crowded pot, though-- a couple small ones are disappearing!
Rick, I'm planning to put most of mine in the ground, but there's something about semps that look great in pots, so I think I will always keep some that way for fun, even though its a hassle with needing to be sunk for winter.. Nice calcareum! Def lots of flowering this year.. probably just old enough for those grown from small offsets in 2009 (just a couple of those flowered last year) and the arach tomentosum from local purchase seems to flower yearly, though we'll see what it does after so many stems this year...
Overall, they seem to enjoy the cool wet weather we've mostly had last couple of years, though I have one or two-- S altum notably, that don't seem to be thriving, and I wonder if they'd like to be drier/hotter--may try one in a small extra gritty pot...

This was said to be Sempervivum 'Excalibur'... it seems to fit the description below with respect to the offsets being on long stolons, at any rate (though not the colour description):

You have some nice collection of semps, all of you! When I started collecting semps, the first was Sempervivum tectorum which my grandma grew on the roof of the "jordkjeller" (= a small storehouse for vegetables, potatoes etc built into the ground and with soil on the roof). I didn't know that many species existed!

So are those offsets from your garden potted up for your NARGS chapter sales or...  ?

Yes, they were for the Chapter sale in early June.  And then I accidentally left that whole flat at home the day of the sale!  But it really wasn't missed.  My pick up was filled with plants bound for the sale anyway.

Is there anything of particular note with S. thompsonianum?

Well, I think it's interesting due to the hairy tufts at the ends of the leaves, but it's all in the eye of the beholder.

Here's a report on it in habitat:

Looking at photos, I'm not sure my plant even is this species now, though I thought I had pinned it down once previously.
Here are the flowers, which don't seem to fit that description:

Any thoughts on what it might be?
