The global keys are a work in progress, as we try to correlate data from various regions. The keys below are for temperate, seasonal regions (with minimum annual temperatures below 0º C), and are currently based on data from Southeastern Pennsylvania. See Bloom Clock/Global Key for more information about the global keys.

Caution: the numbers in parantheses next to each link represent the number of included pages and images. If you are not on a broadband connection, loading pages with over 30 profiles is not recommended!
