Linnea, I have done the same thing. I went through the Master Gardener program a few years back and started planting my county full of hardy, tolerant plants. Old cemeteries, fair grounds, museums, parks, even around the 'welcome to our town' sign. In the process I have met many people and I often enjoy the fruits of my labors as I am out and about. Irises, daylilies and bulbs are some of the plants that will withstand neglect and come back year after year and even multiply.
Barbara, I am looking at widening beds, extending beds, making islands and even cutting a few trees that have outgrown their place near my garden. I also use pots for thinned varieties of irises. I buy pots that match and are not black and row up the re-bloomers and when they are blooming I bring them to the front of the house or iris bed so that they are enjoyed close up.
I also have some very old large shrubs, like St. John's Wart, that are aging out and I have started new ones from seeds in less valuable (iris) real estate, so to speak. This is going to give me more room for it is. I do have a tectorum but it is not planted on the roof...... yet.
