I found $5 geraniums at Lowe's and will keep an eye out for more full-sun greenery, like bougainvillea, etc. that don't need a lot of water. I just happen to have 4 troughs of Asparagus Fern that need dividing. They are also drought tolerant. I am in the midst of planning a watering drip system for it. Trouble is keeping the hoses hidden.
