Pondless Backyard Fountain Pond and Waterfall. Even without the fountain, which in Az will grow algae like nobody's business, I think the idea of softening up the patio with a little rock garden with plants mixed in.
Dwarf Thumbelina Leigh English lavender for small gardens. Perfect for containers and tiny paving pockets and edging. Blooms three times per year. (Small brick border with this lavendar and several pots of herbs along one side of herb garden raised bed)
