I still have some Nagami kumquats fruits on my tree. My kumquats usually get harvested in February but this year its extended itself. I have seedlings that sprouts around the yard but not sure if they are actually kumquats or Yuzu. PM me if you want some fresh seeds or couple fruits ( at this time of year, the kumquats off the tree is not as sweet as in couple months ago but seed should not have problem sproutings).
