Re: Updated seed lists

I find Euphorbias tend rot, often before they germinate, if kept hot and too wet . Resist the temptation to bury them very deep, even if they are large seeds. Barely covered seems to work. Of course, it's a vast genus so there may be much variation between species.

Re: Is rebutia perplexa self furtile? Solved

From the ADBLPS list~

1416 perplexa [JCV/92] f -4 à 5-d1-18 10g 0,7€

The f (underlined) shows the species is regarded as self fertile, an "s" would mean self sterile

Re: ID please Solved

It's a normal process to drop the leaves, although if it's well hydrated, it will probably keep them a bit longer than if it dries out more.

Re: Is rebutia perplexa self furtile? Solved

Many Rebutias are self fertile. According the extremely useful key on the ADBLPS seed list, R. perplexa is one of them, so you should be able to get it to self seed.

Re: Eppy. Query

Give them a chance, they start angled and can quite abruptly start to produce flat stems:http://www.flickr.com/photos/oceanrain/3153576353

Re: Stomatium pyrodorum - varying leaf forms?

Thanks Ian.
They should grow a bit more compact now, as they are going to be kicked out of the hosue into the cold frame on a permanent basis soon.
If/when flowers arrive, I may repost for further opinions.

Re: Stomatium pyrodorum - varying leaf forms?

Thank you both for your replies. The seed source was Succseed. I've kept them growing a little over winter as I do many 1st year seedlings, trading off a little etiolation for size/robustness. Hopefully they will grow a lot more compact as spring extends into summer. So, any guesses guess on the ide...

Stomatium pyrodorum - varying leaf forms?

I have some Stomatium pyrodorum SH397 seedlings from last year, and I see 2 different leaf types. Some plants have spathulate, more or less toothless leaves. Others have narrower, precisely toothed leaves, making neat little "jaws". Each individual plant seems quite consistent in the form of leaves ...

Re: alluadia minimum temperature

Dave's Garden gives first hand reports of some of these taking frost ok (or ok-ish, depending on species) in the USA, so I'd have thought that a slightly cooler green house treatment would be fine: https://davesgarden.com/guides/pf/go/53187/ , https://davesgarden.com/guides/pf/go/61362/ Other Southe...

Re: Please can I have a list of minimum temperatures by species?

I've had Euphorbia horrida and E. tuberculata (= caput-medusa) in the cold frame this winter. They have seemed fine. No heating, no bubble wrap or extra cover during cold snaps. I'd cautiously extend to a few other species not already mentioned, but certainly not most members of the genus.
