As my post history might tell, I have recently sown a batch of seed list seeds (from here and the MSG) and while most of the pots look pretty promising, I am afraid I contaminated two with mould spores. Aylostera heliosa condorensis already germinated two seedlings (marked with arrows), but there is...

Thank you all for useful info and links! Seems like the middle one can simply be the "f. medio" I linked to, so just a different form of pyramidalis. I'll definitely read all the http://www.crassulaceae.ch materials, a quick glance was enough to tell it's a lot of quality information there...

I do not have the C. marchandi (a lovely one, just landed pretty high on my wishlist - would you consider a cutting swap?), so don't have factual experience here, but from its appearance it might have similar needs to barklyi, which for me means watering every month or so. Pyramidalis seems to be ha...

For some time already I am looking for a written reference (online or maybe a book photo/scan, I was referred to G. Rowley's "Crassula. A grower's guide" as the best currently available resource about Crassulae) on the third Crassula I have below. The right hand one is a "classic"...

A book I used a lot in my earlier days in deciding which genera and which species to grow was of course John Pilbeam's 'Cacti for the Connoisseur' [...][/url] Thank you Tony, this book looks exactly like what I was looking for: "A detailed guide to the plants native to harsh environments that ...

I recently had a pretty hard nut to crack while choosing seeds from the Forum Seed List - which cacti to choose?! This made me wonder if there exists a pretty generic, maybe even just (?) morphological overview of the most popular cacti genera and species? Something, that would answer questions like...

Thank you Ian! I chose the species mostly visually as I had not even a single cacti, sad to hear they are slow growers! May I ask for a bit of clarification below? [...] The mesembs not so long, I bring them into the fresh air soon after germination seems complete. Is there an upper limit for their ...

I did say in an earlier comment that I would be judging photographs rather than plants, not sure which entries are old/difficult to grow so I my shortlist of potential winning images were entries from (in no particular order) MarDz, HaoBao, rodsmith and el48tel. After much switching between tabs wi...

[...] and stand back so you don't get hit by the rapid growth. I see what you mean, less than 96 hours and they already have 10 mm! May I ask if there is anything on the list below (that I sowed in this round) that would need much different treatment than "wait until germination and gradually ...

For clarity I will reply to my own post rather than editing the original one. After closer inspection of the photos I think the white, fuzzy "things" are actually roots of the seedlings. They all start where roots should be (clearly visible on the one that fell over) and every seedling see...
