Having found the lost label, I can now stop calling it a Rebutia! Here is the Weingartia longigibba that I posted in bud the other day.
It’s a very old-looking plant, about 8" tall, that I picked up from a collection disposal; it’s a bit tatty round the edges, but it gives a good display.

There were about a dozen turbs at it yesterday - several T. krainzianus, an un-named "sp." (which is more than likely a schiedickeanus ssp. notquitesureii), and a few of the ever-reliable Turbinicarpus pseudomacrochele.
This was the nicest one out; I’ll snap some of the krainzianus plants today if the sun comes out.

This plant of Mammillaria magnifica is usually in flower by now, but the gloomy weather we’ve been having seems to have held it back.
It’s one of only four large (ish) members of the genus that I grow, the others being karwinskiana ssp nejapensis, zeilmanniana, and a plant that may either be marksiana or canelensis.
This one was bought at about half the size it is now, as an impulse buy from Badger Nurseries in Studley. At that time it consisted of just the main head, without any offsets. The offsets began to show a couple of years back.

The yellow-flowered Delosperma congestum is having a rest at the moment, but when the ultra-violet began to make its way through the clouds yesterday, some of my other outdoor mesembs obliged beautifully. By the time I got the camera out, the light had changed again, and the flowers had retreated but you get the idea!
These are three different cultivars of Delosperma sutherlandii.

Second set of flowers for the year!
I do think that this Mammillaria species is tremendously good-looking; it’s a super woolly jumper of a plant, and one of my favourites.

The natural habitat of Blossfeldia liliputana is out of harm’s way in small South American rock crevices, with little by way of organic material for growing medium and a degree of shade.
Having three plants on their own roots, I decided that they looked rather lost in a 2" pot on the staging and cast around for some raw materials to make them a new home.
I found a nice piece of Cotswold stone in my mum and dad’s garden, and armed with a tungsten drill bit, a masonry chisel, and a lump hammer, I set to work.

There is an excellent article on Cactiguide.com by Andy_CT about making hypertufa. He’s promising a follow-up article dealing with curing etc.
The article is here.

It’s the end of May, so, of course… it’s time for flash photography! Light levels are so poor this evening that there was no other way of capturing the buds on these two plants, Rebutia neocumingii (formerly Weingartia, although I’m not sure which one, as I can’t find the label, so I’ll give it the newer name for now) and Lobivia arachnacantha (or if you like to use the massive uber-genus Echinopsis for everything that isn’t an Eriosyce, it’s now Echinopsis ancistrophora ssp. arachnacantha). Both plants have lovely flowers, but there’s something very pleasing about the buds too. The Rebutia is, of course, on the left.

Now that they’re growing, I’m continuing with my experiment in keeping Fraileas in pseudo-bog conditions such as those they experience in habitat.
The results so far are quite dramatic.
I thought they’d fattened up well when I first started watering them, but now the best ones are like little balloons, and have nice fluffy buds.
I’m hoping that the increase in water will encourage them to flower rather than set seed cleistogamously this time. If it does, it’ll be the first time I’ve ever seen an open Frailea flower “in the flesh”, as it were.
On the left is Frailea mammifera ssp. angelesiae, on the right Frailea phaeodisca.

I’m not really much of a grower of leaf succulents. I’ve recently become more interested in such genera as Haworthia and Adromischus, but the rosette-forming Echeveria types have never really held much appeal for me.
However, I received some free Graptopetalum bellum seeds from a well-known seed supplier when I purchased a largish consignment of square pots from him, and dutifully sowed them at the beginning of March.

I’ve only recently acquired a liking for Coryphanthas, and bought a few seedlings with a view to growing them in the unheated greenhouse, when I get round to building it, as they are pretty cold-tolerant.
I noticed yesterday that this plant is now in growth. I’m a sucker for plants with pectinate spination (Escobaria minima is another favourite) and I think the new pink spines on this young plant are particularly attractive.

It’s always nice when cuttings announce the fact that they’ve rooted.
I was given a decent sized piece of Puna clavarioides before Christmas, which is showing signs of taking up water, but obviously hasn’t developed enough root to really fill out yet.
However, this little chap broke off the larger cutting, and by contrast is well away now. After months of gradually losing weight the body is firm and plump, and clearly responding to water quite happily. And, most importantly, it’s very firm in the pot.

I’m finding mesembs incredibly rewarding to grow from seed.
Being used to the growth rate of cactus seedlings, it’s marvellous to see these little plants assume adult characteristics so quickly. A little while ago, my Titanopsis fulleri seedlings were only just embarking on their second pairs of true leaves (see left). After a good few weeks spent in full sun, they’ve changed dramatically.

There’s something of a lull in my greenhouse at present. The Rebutias have just about done their thing for now, and most of the turbs are taking stock and busy preparing their next phase of flowers.
My adult Melocactus is doing a fine job, however, and is popping new fruits and flowers out on an almost daily basis. The cephalium has grown well so far this year, and has produced a decent amount of new wool.

This is my first year keeping Digitostigma caput-medusae. I have a couple of double-headed plants, which are tubercle grafts, grafted on the spineless form of Ferocactus glaucescens (thanks to Marlon for putting me straight on the identity of the stock).
They didn’t adjust to the first spell of bright sunlight this year to start with. They went a deep purple colour, which is something some of my other Astrophytums do anyway. Of more concern though was that the tentacles lost turgidity and went extremely floppy, as it took a while for their stocks to decide to take up water. Now, though, they’re growing strongly, and this plant has surprised me by putting out an offset which is shown circled here.
