This is well put together. The PDF has a single page ordered by bloom time within the season. For each plant, it lists the water requirements and rough height: this quickly lets me know whether a plant will fit in a particular location in my yard. Otherwise I go looking for plants, find what seems to be nice then after digging up the details find out it doesn't match the location. These PDFs are sorted by US region but for those outside the US, this may still be useful if your local climate happens to be close to one of the 10 listed here.
