Aloe cremnophila
It's a propagation of ISI 1450, which in turn was propagated from the type collection Reynolds 8450B which was used by Gilbert Reynolds to describe the species in 1961.
The plant was first collected by Peter Bally in October 1956 on cliff faces of the Daloh Escarpment, about 13 miles N. of Erigavo, Somalia. It is currently known from no other location, so it's a very narrow endemic.
It was named cremnophila because it only grows on precipitous cliffs, i.e. it's cliff-loving or a cremnophyte.
It's closest relative might be Aloe jacksonii from Ethiopia.
Here's it's shown in a 25 cm diam. pot, which I actually have as a hanging pot.
Cheers,
Colin

Re: Aloe cremnophila
Here's the flower spike, about 30 cm tall, with individual flowers being about 26 mm long.
Brian, do you find that it's a somewhat shy flowerer?
Reynolds grew several plants and after four years these only produced a single flower spike, which he used to base his description of the new species.
Anyhow, thanks again for the plant Brian. As you can see, it's grown well for me, but I suspect that its reluctance to flower with me isn't unique.
Cheers,
Colin

Re: Aloe cremnophila
Wow Colin, well done. I'm afraid you put me to shame. I still have my plant(s), but without the room for repots and TLC they have not done very much. Certainly not flowered but proving to be very tough and resilient! Probably not too floriferous until a bit bigger, like yours is becoming.
I agree with your comment regarding relatedness to jacksonii. They both share a very similar leaf epidermis which appears to be fairly unique. Very useful information you give too.
Great to hear of your success!

Especially interested in Mesembs. small Aloes and South African miniatures and bulbs.

Beautiful, Colin. I love that vibrant leaf colour. If I stare at the first pic too long my eyes go googly!
Happy carrier of Forby Disorder - an obsession with Euphorbia obesa.

Re: Aloe cremnophila
Thanks for the feedback Brian. You're certainly confirming that it's a reluctant flowerer. Think it's time you gave this interesting plant some TLC. You could always chuck out some of the mesembs to give you more space for the aloes - they deserve it.BrianMc wrote:Wow Colin, well done. I'm afraid you put me to shame.

Re: Aloe cremnophila
Glad you like it Julie even though it's not a Euphorbia. Maybe I can convert you to some succulent monocots.Colin Walker wrote:Thanks for the feedback Brian.

Re: Aloe cremnophila
Very nice, Colin. Indeed, nearly as nice as some of those other succulent monocots - why, Gasteria of course.Colin Walker wrote:Maybe I can convert you to some succulent monocots.

Re: Aloe cremnophila
Colin/Brian
What light levels do you grow this in? I have a plant but stems have longer internodes compared to Colin's, so probably somewhat etiolated and not getting as much light as it would like. It's been under the staging, so little direct sunlight. Plenty of new stems from the base - will older stems root if I remove them? Although the stems sprawl along, they don't show much interest in rooting as they go. The sprawling habit means it's never going to find space on the staging. Any experience of growing it outside over the summer?

Re: Aloe cremnophila
Mike, my plant is currently grown as a hanging pot high up in the greenhouse, so has had relatively high light levels. Compared to my plant yours does look a tad etiolated. I wouldn't recommend growing any aloe under the staging, but that's just my personal opinion. I'd recommend a hanging pot for this cliff-dweller since in the wild it grows hanging down from vertical cliffs. My plant also shows no signs of sending out roots from along the stems. I'd recommend a repot since your plant does look under-potted. My plant is going to be repotted into a large clay pan once it's finished flowering. I've as yet no experience of growing it outside during the summer, but I might try it with a rooted cutting to see how it fares.MikeT wrote:Colin/Brian

Re: Aloe cremnophila
Sounds a good idea but... The space available for hanging baskets is full with a couple of Aporocacti, a couple of Sedums (morganianum and 'Canny Hinny') and last years new acquisition of Cleistocactus winteri coldemonono. In fact it's more than full. I think the only practical option I have is to put it outside for the summer, after a repot.Colin Walker wrote: I'd recommend a hanging pot for this cliff-dweller
Wouldn't argue with the theory. But I only have a 6 x 8 GH, so just not enough space. It's one of those aluminium and glass ones - just not elastic at all. Poor design really.Colin Walker wrote:I wouldn't recommend growing any aloe under the staging
