sure, for green areas it isn't, for paved ones it IMO is.

add access=private?

why not? As long as people do want to do this and only tag what is
there, I don't have a problem with it.

leisure=park is not the right choice, sure. But leisure=garden could
IMO qualify. a) because it is at least in some areas common practise
;-) and b) the size of the garden is already determined by the size of
the polygon.

If you use this tag only for huge gardens of estates/castles it is
more or less useless and hard to tell the difference from a park.
Parks also have sometimes fences around them, limited access, no
access, fee for access, castles / mansions and others inside them. Big
gardens are basically parks!

Gardens on the other hand can be completely different, from french
barocque gardens to English gardens to zen gardens (not even green).
All of them are usually much bigger then the usual detached house
garden, and can therefore simply be differentiated automatically just
by their size (e.g. mapnik can do this without any "additional
processing" just by standard rules). For human readers of the map it
is even easier.


I therefore suggest to use
leisure=garden

and add subtags for the style (some might suit only bigger gardens):
garden=Chinese
garden=English
garden=à_la_française (for French gardens)
garden=rosarium (for rose gardens)
garden=unclassified (suitable for many small private gardens)

and maybe also subtags for the use:
a) flower garden
b) fruit and vegetable / kitchen garden
(what tag could suit this? type?)

cheers,
Martin
