I found a few feijoas growing around town around businesses and in parking lots. They were surprisingly good, and actually larger and had more fruit than the Nazemetz feijoa tree I bought. I picked these up from the ground. I'm surprised at how many feijoas were growing, even though I assume they were just ornamentals and never hand pollinated.
The more oblong ones on the left were from a parking lot around a shopping center more gritty in texture, they had more meat vs pulp. The skin texture was more rough, thick, lighter green. The taste was sweet, but sour too, they were good feijoas. The skin wasn't too good.
The ones on the right, the more round feijoas were ones I found at a parking lot around a business center. They have more pulp than the ones on the left, and it had a more jelly-like texture over the gritty pear-like texture of the feijoas on the left. The skin was more smooth, shiny, and thin. The taste was sweeter and more intense than the ones on the left, and the experience was more like eating a jelly than a fruit. The skin had a good lemony taste.
I preferred the ones on the right more. But overall- I'm very surprised at how good quality parking lot feijoas can be. They were probably planted as decorative plants from seed in the 70's and 80's. I assumed they would just be tasteless and poor quality, but they were sweet and delicious with a nice scent.
