The Keys on the bloom clock are the first "results" of the clock, allowing users to identify plants by color, type, location, and time of year with the aid of photographs and other illustrations.
We now have Global Keys, though they are still in the early stages of development:
- Temperate climate keys (for regions where seasons are controlled by season, and where average minimum temperatures are at most 0º C).
- Southeastern Pennsylvania (sorted, January through December)
- New Hampshire (unsorted, April through November)
- Southwest Oregon (unsorted, August)
- Central Pennsylvania (unsorted, August through November)
- Aurora, Colorado
- Southern Ontario (under development)
- Manchester, England (under development)
- Bootle, Merseyside, England (under development)
- Central Bohemia
- South Bohemia
- Leipzig Lowlands, Saxony, Germany (under development)
