Does anyone have experience hybridizing euphorbias. I have a number of euphorbias, some flower year round (E. milii & E. genoudiana), but only my milii ever set seeds. Can anyone advise on cross pollinating euphorbias. Are the plants usually male and female, or do the flowers have both pollen on the stigma? The actual flowers are so small I cant imagine how to go about cross pollinating. Any insight is appreciated.
