I loved reading what Garden Blogger Bloom Day means to different people, including that it serves a record-keeping purpose for many of you. Plus, it's just fun to do.
For record-keeping there's also the not-so-beautiful but reliable bar graph, a wonderful vehicle for conveying information. Each block in the graph represents one week of bloom, and as a group they clusters plants that bloom at the same time in a way that's really easy to grasp. Each border or garden area has its own graph.
The result: I can see what times of the season there's not enough blooming going on. When people ask to see something in bloom I can give them a good approximation of the dates. And so on. This first and only version in 2002, four pages in all, has served me well.
