I've germinated D. falonceri, D. paradoxa and several hybrids. No special treatment, just sown into pots, bagged and put in the tank with the rest of my Petiolaris plants. They like higher temps to germinate than I normally keep my tanks, thus the lower germination rates. I've given seed to several growers and they've had success germinating them.
