Hi,
Mine started blooming as of end of July. I have all sort of bees around the bush.
I'm still waiting on mine to set fruit. They probably like fresh weather, and for now the weather is perhaps too warm for the fruit to set, but it makes lots of flowers, a shower of flower (since I tried it shower like) ... Or I have a random bad goji strain ...
I had to pull 4 volunteering cuttings, already rooted and growing.They were just cut from the mother in April and thrown to rot on the dirt...
Good luck with yours.
