Assembling enough data to prepare a good calendar of seasonal interest presents a problem:  do you describe a season using using words like "early-spring", or do you attempt to force-fit a season onto a calendar.

The Compleat Botanica uses a special date-range tool which gives you an at-a-glance look at each specimen's blooming season, planting and harvesting season, hay-fever season, and season of special interest.  This date-range tool uses a simple click-and-drag operation for specifying starting and ending dates for the season.  The same tool is used when you want to filter your collection to only include records for a particular date range.  Preparing lists of "What's in bloom" or "Early October autumn-color" or "Berries in December" are simple examples of what's possible.
