Back in December of 2016, I tasted feijoa fruits from the plants at Gilroy Mall. A couple of bushes were still abundantly producing tasty fruits.
Two photos below are from December 10, 2016,
I collected the scions from these in the following spring, grafted onto seedlings and planted them in ground in Vacaville. I named them Gilroy Corner and Gilroy End. These year I have fruits on both plants and they just started dropping the fruits on October 30.
