Have a terribly posh tea party with cucumber sandwiches, perhaps followed by cream cakes, scones or muffins.
Or simply have tea and biscuits (cookies).
Weather permitting have 'Tea on the Lawn' & perhaps a game of croquet for the wedding shower. Have a bash at speaking with a British accent; that should be rather amusing in itself.
Garden Tea Party Games ~
Croquet. If you are unable to obtain a croquet set, then it shouldn't be too difficult to make the hoops from wire & a mallet from timber. There are several web sites with information on croquet, including croquet.org.uk
Favors ~ These could vary from tea bags in envelopes to small ornaments or both depending on the anticipated value of the shower gifts.
Gift suggestions for a Garden Tea Party ~ China cups plates, teapot, cutlery, and other suitable items. In addition, perhaps a tea set or similar could be bought by a group of the guests.
