neat planting, mark! what will you do with the area immediately around the wheelbarrow?

interesting that your semps are all green now..mine are probably at their best earlier in the fall, with lots of variety in colour, now they are pretty much all red (some exceptions), but rather dull looking and a bit shrivelly... of course we have had much lower temps by now than you..

The area around the wheelbarrow semp planter will also be developed, dug out, carved, sculpted, planted... too early to say what it might look like, I generally just go with the flow, and start digging and making stuff up as I go :D  I'm low low low on funds due to being unemployed, so can't buy rock or other expensive landscape materials; will need to use what's there and depend more on the plantings.

A few of my semps have gone over to a dull winter red, most of those I used for the wheelbarrow are ones that color well in spring and summer.  I do have a nice clump of S. zeleborii that is a good red right now, it's going into the planter, but it'll need to dry out a bit; poured rain all day today, will be the same tomorrow.

looking forward to updates!

i can relate to the low funds--only working part time here, by choice, so i haven't even priced stone/gravel yet.. i have a fair amount of stone (all more or less smooth/rounded glacial deposit stuff from local fields, quartzite, granite, a bit of sandstone, etc etc)from my old rock garden and places my mom used it over the years, but i could really use some gravel/grit for top dressing and loosening the soil....

And this is very, very special. This Sempervivum is Sempervivum sp. (S. cantabricum subsp. gredense comb. provis.).

While waiting... this plant does not have a name! Most probable being that it is a form of S. cantabricum, one will thus attach it temporarily to this one with the row of subspecies. It is inconceivable to recombine the epithet paui Fernandes-Casas, for very much reasons. It is therefore necessary to create a new denomination for this plant, for example:

S. cantabricum subsp. gredense ---

Caution, it is a combinatio provisoria which, not having been published, does not have any nomenclatural value.

Khalid, how exciting that semp species are native to your area and you can collect various forms. I really like the dark-tipped ones with pale centers. The S. montanum rosettes are plump indeed and very glandular, attractive.  As much as I love the Semp and Jovibarba hybrids cultivars, so many of the species are wonderful too, giving a good basis and better understanding with which to judge the cultivars.

Thank you very much.
In my area there are no sempers (Valencia) and is very difficult growing sempers in mediterranean weather, but I grew very much years and all is well. The sempers of my collection were purchased from a German specialist seller(Erwin Geiger). I saw very much sempers very years ago when I traveled to the Pyrenees. Is fantastic see in habitat.

That's a fine collection of Spanish sempervivums Khalid 8)   

Last summer I found a nice one near Puerto de las Señales in the Cantabrian mountains (originally shown here but reposted below).  Can you say which ssp it might be?

Hi Khalid,
I really like this one too. Would probably add it to my small collection if I could find it in the UK.
You have a good collection there.

Hello Khalid!
lovely selection of semps--the new one is really nice--an excellent 'plain' form!
your semps are a little luckier than mine, just now: I measured today, and snow on my land is from 12inches/30cm to 16inches/40cm; my rock garden in progress, where pots are buried in the soil for winter, is at the low end of that;
A big pot by the house, where snow is moved off the path, is in a pile around 3 feet (nearly 1m), so almost 2 feet/60cm of snow on top of the pot..
Still nothing compared to mountain regions, but about average for us at this time of year..

Sempervivum and Jovibarba- new online source
« Reply #149 on: May 18, 2011, 01:50:19 PM »
I know that many of us find the different Sempervivium cultivars hard to resist and so I think that those of us in the UK and EU will be interested in a new (to me) web-based nursery, specialising in Semps.

The nursery is run by Andrew Whelan in Northamptonshire, who has developed his online business as a result of his private enthusism for these plants. He's breeding them, too!  
 
There is a super selection and he offers free delivery though he can only sell to the UK and EU

That can't be  bad and his prices seem perfectly reasonable.... that's always a good point, too  ;D

The website is www.sempervivumnursery.co.uk

Hope you like it!
