Garden Rooms ambush the rule: 1 Focal Point/Area. Each garden room is allowed its own focal point.
What about all the stupid little things? Focal point bench, above, softened with plantings in the pot cluster. My broken head collection is used as a Subsidiary Focal Point. Watering can too.

Tucked into the Hydrangea 'Anna Belle', the blue/white egg is hidden from most views.

Ezra, my Gethling, above, tucked into a shady spot. Most people never see Ezra indicating he's a well placed subsidiary focal point.

Subsidiary Focal Points are delightfully devious to children. They GET the fantasy. Who knew? Gardening fully for yourself is gardening for children too.
