And do they have nothing like 1-800-FLOWERS?

At first it depends on what you need:
Just verify if it is a valid (German) phone number or get the number in a defined format.

In any case it might be better to split the processing into multiple parts.

So you might for example replace the optional international prefix with a single '0' at first:
# or
/^\+[0-9]{2}[ -/]*/0/
If you need to get the area code separately look for the next non-digit character. But that will not work for all inputs.

Finally remove all separation / delimiter characters (space, minus, slash). The final string should contain digits only and can be checked for min. and max. allowed length.

You can never know if a number is a phone number or look like a phone number, it depend on context.
As fa as I know, German phone number comes with different number of digits.
+49 is the international header to Germany.
Spaces and dashes are artificial separators depending on user, and grouping can differ to make number easier to remember.
I would try something like:
((\+49[ /]*)?(\d[ /]*){10,11}\d)
