It's that time of the year. You can always count on receiving IRS tax forms and gardening catalogs in the days following Christmas. Both point toward spring deadlines, but perusing through the catalogs is a lot more fun. In the cold and overcast days of January, it's nice to sit down with paper and pencil and, with the catalogs, plan your spring garden and dream about warm, sunny days. I've done my share of that, as did my father and his mother before me. Below is a drawing I found stuck away in some of my grandmother's gardening magazines and clippings. Pearl Cofield Robinson loved her flower gardens, and irises were among her favorite flowers. Her planting diagram came with a bonus - it was written on the back of my grandfather's stationery from his service on the Board of Supervisors, otherwise I would never have seen his letterhead. The advertisement came from one of her gardening magazines published in 1965.
