Flowers for use in a Flower Clock
|NASS Member Robert

article in the NY Times about how certain flowers may be arranged to
indicate clock time according to when they open or close during the day.

open and close at regular hours. They can be old friends like lilies,
marigolds and primroses. Next, plant them in an organized fashion ó perhaps

Europe as a result of the work of Swedish biologist Carl Linnaeus, in 1751.

birth, such a floral clock may have been described by Andrew Marvell, in his
poem "The Garden" (1678):
There is also a mention of this approach in the early BSS Bulletin Vol 91.3 p4. The plants suggested in that 1991 article together with their opening and closing times were:
