When to prune Fatsia japonica's flowers?

Hello and Happy New Year to everyone.

I am in a rental property and have a Fatsia japonica in the front garden. Never had one before and I really like it and was surprised to see what look like flowers growing.

Now I am wondering when/if I should cut the flowers (if that's was they are?) please?

It was very popular with flies and pollinators, but now it is a bit colder I haven't really seen much activity on it.

Anyway, don't want to damage it, I like the flowers, or whatever they are, just want to do the right thing by it

Any advice or guidance would be great, many thanks in advance.

 

By the spring they will have turned into black berries.

I usually cut them off around that time as the berries drop and make a messy stain on paving.

 

Oh, that's interesting @pete, thank you.

Are the berries something birds will eat please?

It's in the front border, so won't make a mess anywhere important, but if they aren't food for something, then I will cut them back when they turn

 

I've never seen birds eating them, but it is possible I suppose.

I think Fatsia has some connections botanically with Ivy, so maybe.

 

Thank you @pete sounds interesting and will see if there is any interest in the berries

 

The flowers, like Ivy flowers, are an important source of nectar for Bees and other pollenators so if you want to cut them off wait until the berries drop off.

 

Thank you @strongylodon I will definitely leave them until they drop, looking forward to seeing who enjoys them!
