Here is one cell of my native hibiscus crosses. It took 5 weeks from flower pollination to pod harvest in our warm spring, which seems about the average for all the crosses. Four more weeks for 40% of the seeds to germinate (lightly abraded against concrete brick before sowing and then keeping in a mini-greenhouse in shade outdoors). In fact, this is the best germination rate I've had so far as most of the crosses sown in Oct-Nov have not germinated yet. Germination generally seems quite erratic, as one batch took only 15 days for the first seedling to germinate. Mind you, 22 seeds were sown so the germination rate (e.g. 1 out of this batch of 22) so far is poor.
