Dusk bloom clock

FIELD RESEARCH:

The Evening Primrose is a dusk clock. This four-minute movie shows how it blooms at the close of day, like a bell intoning as the Sun slides toward the horizon. The video’s speed hasn’t been altered. If you watch carefully, you’ll see how the bloom’s bursts of movement seem to beat the time twice.

I made this video as part of (my fictional) Stereochron Island campaign to promote alternatives to the mechanical clock. It’s companion timepiece is the Sheep eye clock, which shows the hour leading up to dusk.

The Evening Primrose is one of several flowers that bloom, open or close at a particular time of day or night. As part of Stereochron’s field studies, I made this rough sketch of a flower clock, below, drawing on Linnaeus’s famous 18th-century plan for a Horologium Florae (Floral Clock). (The symbol < means it opens at this hour, and > closes.)
