Even in narrow and sparsely furnished gardens like the above, it is usual to introduce rocks and slabs of stone which do duty for such features as the "Guardian Stone," "Worshipping Stone," "Stone of the Two Gods," and other lithic features of Japanese landscape gardening. The principal stone lantern is placed near the "Guardian Stone," which occupies the most important angle of the oblong passage. When a detached lavatory is introduced, it must have its screen-fence and water basin, and planted near it should be some of the following trees, shrubs, or plants:� Pinus parviflora, Nandina domestica, Buxus japonica, Nuphar japonicum, Gardenia florida, Polypodium tricuspe, Ardisia japonica, or different varieties of the Rhododendron. Flowering trees are often grown in Passage Gardens, the surrounding areas being then invariably covered with sand.
