After trying to using a software program for a while I ultimately went back to Excel. Can't beat having everything on one main page, sortable, with any data cells you want, and unlimited entries and new tab pages, etc. Some tabs get more use than others, but they all record as much or as little info and pictures as desired. And, each year's set of spreadsheets can be saved separately at the end of the growing season. It's great to be able to "go back in time" and see where something was planted two years ago, revisit old wish lists, etc. So far, it has worked quite well for managing about 200 cultivars.
