Information about the world's first flower clock

The world-famous Swedish botanist Linnaeus in the 18th century made the world's first "flower clock" by arranging various flowers clockwise in a carefully designed flower bed based on their flowering times.

The bud opening times of several flowers are excerpted as follows. From this, we can see the light intensity requirements of different flowers when they bloom. When planting flowers, you can try to meet their flowering light requirements, and it can also be used as a reference when appreciating flowers:

3 o'clock: the snake bed flowers bloom; 4 o'clock: the morning glory blooms; 5 o'clock: the rose flowers bloom; 6 o'clock: the nightshade flowers bloom; 7 o'clock: the peony flowers bloom; 8 o'clock: the lotus flowers bloom; 9 o'clock: half of the lotus flowers bloom.
