I found this growing all by itself in the bottom of one of my trays, which mainly has Crassulaceae in it and a few cacti. Having grown on a bit, it now appears like nothing I have in that tray.
Can anyone ID it, or even make a suggestion? I suppose it could be a hybrid of some sort.
Perhaps I'll have a clearer idea when it flowers.

Re: Mystery plant
Lenophyllum?
If it is, easy to introduce as a single leaf hiding in a pot of something else.

Re: Mystery plant
It almost has elements of Lenophyllum, but not quite guttatum.
Sorry Mike you posted that as I was typing!

Re: Mystery plant
Yes, no idea of the correct name, but this THING is as bad as Oxalis, and definitely worse than Bryophyllum sp in the glasshouse, and I would recommend urgent removal and eradication. I have found it to be frost hardy in rural Hampshire for at least the last 10 years! DESTROY !!!!

Re: Mystery plant
Yes, thoroughly agree with David, it grows on aluminium staging, concrete flooring, anywhere a leaf drops. It's just about indestructible, unaffected by glyphosate sprayed under the staging. Pull a plant out without too much care and it sheds leaves everywhere, the leaves blend in well with top dressing and take some removal if growing at the base of a spiny cactus. I've seen nurseries covered in it! As David said - exterminate.

Re: Mystery plant
I had Lenophyllum texanum at one time. Under the staging it's a straggly, scruffy looking plant. In full sun, it can make quite an attractive, compact, silver coloured specimen.
The International Crassulaceae Network comments about texanum
Note :
In the greenhouse this plant can become very invasive, and nurseries consider it a pest. Leaves and bracts detach and root easily and produce multitudes of new plantlets.
Despte my positive comment about how it can make an attractive plant, I eventually took exactly the approach suggested by Stuart and David. This involved quite a lot of effort, but I did succeed in eradicating it. That was in a 6' x 8' greenhouse. Multiply the effort involved by whatever size greenhouse it's been allowed to spread around.

Re: Mystery plant
I do appreciate it when "eradicate" is used in line with its etymology, derived from "root out" in Latin.

Re: Mystery plant
Yes, I was reminded of that. I have L. guttatum and L. reflexum, and find neither specially easy to grow.
Perhaps it did come in from elsewhere, but I repot plants as I acquire them, so it is unlikely to have come in unnoticed except as a seed. If so - why would it be in the bottom of the tray? I think its more likely a hybrid of a couple of things I already have, and a ripe seed dropped into the tray.
Edited: forget the above, and read on...

Gulp. Quarantined, before it can flower.

Re: Mystery plant
Yes, seems to be Lenophyllum texanum.
Its problem is that the leaves fall of at the slightest touch.
I think I got them all when removing it.
Thanks for the warning, everyone.
