Hi All,
A photo of Lithops viridis. Pity only one has a flower though. I would have liked to have tried to pollinate them.

Re: Green Stones
Very nice. This one is near the top of my wants list. I know several people who have them but seed seems to be near impossible to find in Europe at the moment. Definite shame you can't pollinate!

Re: Green Stones
Its always worth trying some other pollen on it, sometimes they set seed and you have nothing to loose.

Re: Green Stones
How does the other pollen work Roy? Wouldn't that result in a cross? I don't know if all those plants in that pot originated as one plant. If they did they would be genetically identical anyway. So having more than one flower wouldn't make any difference. I always tickle one flower and hope for self fertilisation if I only have one plant (In general, that is - I've only got two Lithops and only one of those has flowered).

Re: Green Stones
Hi Frank,
What a deep fissure they have!
You could try crossing with any distantly related Mesemb and hope that it induces self-pollination. I believe SH says this works some times.

Re: Green Stones
It's not exclusive to lithops, its been known that cacti can be made to produce fertile, non hybrid, seed when stimulated with pollen from unrelated plants.
Steven Hammer states that some Lithops can be stimulated to produce seed by being "tickled" with their own pollen. He also states that very occasionally a single Lithops will be self fertile and produce fertile seed by itself. He suggests that if you are trying a foreign pollen, Conophytum herreanthus, Fenestraria rhopalophylla, or Agroderma delaetii might be good ones to try. He thinks the foreign pollen is not genetically absorbed in any way it merely breaks down the plants resistance to its own pollen and allows it to work.
As always, play around a bit, you may find out something useful to all of us

Re: Green Stones
That's an interesting piece of botany - fascinating stuff. I'll try it whenever I get the chance. I have only one of most things and rarely get any seed. Not that I need to grow more of what I've already got, but it would be nice to contribute to the seed pool.

Re: Green Stones
Last evening I tried some pollen of Tanquana. Hopefully something will happen.
