Note 156 — Chapter XXIII

Dandelion opens at five or six in the morning, and shuts at nine in the evening; the goat’s-beard wakes at three in the morning, and shuts at five or six in the afternoon. The orange-coloured Escholtzia is so sensitive that it closes during the passage of a cloud. “The marigold that goes to bed wi’ the sun, and with him rises weeping,” with many more, are instances of the sleep of plants.
