A little while ago I sowed Euphorbia obesa seeds. These little balls intrigued me and of course I didn't just want to buy a grown up plant.
The seeds are quite big for succulents. I sowed them onto wet sand and only pushed them into the soil a little bit.
After a few days they germinated. Interestingly the seedlings grew quite long within only a few days, even though they had enough light. But even in these seedlings you can already see the "obese", succulent part.
