How long should it take for the seeds to ripen on C. seidelianum? I crossed the heck out of mine and got one seed pod that ripened in 45 days, 29 June. I planted the few (bigeneric) seeds and got 75% germination. However, none of the other seed pods have ripened, which doesn't bother me, but none are showing any signs of decline and several are rather swollen and I expect to get more seeds.
