I have three growing outside here in the central coast of CA. Originally grown in greenhouse, they are 6-7 ft tall and have been planted outside for 3 years. They have flowered, but small fruits fell off. They have taken 27 degrees this year (once), but our freezes are of short duration. Growing like mad now, hopefully will get fruit this year. Counting on and accepting global warming (we used to get 22-26 degree freezes 30 years ago, now rarely below 30.) Apricots used to grow commercially here, now we get few due to lack of winter chill. Comparison: two covered mangos (4 ft) only lost new growth this year (their first year). We lack any real heat, summer highs in the mid 70's, which is another limitation.
