I’m up in the SF Bay Area, not LA, but I’ve been stealing loquats off trees overhanging the street for two decades, and maybe 10-12 years ago, my then-gf / now-spouse and I tried sprouting a few of the seeds. One of the descendants is now happily growing in the ground in the yard of the house we eventually bought, after having lived in a series of increasingly-large pots for many years. They can be eaten in a manner somewhat similar to lychees, or can be turned into jam.
There were loquat trees all down the block next to my elementary school in Daytona Beach, Fla. I was the only person I know who ever ate them, and loved them!
Amazing to me that they are all over Los Angeles too - not because of the climate, just because I didn’t know anyone else grew them.
