quotations about leaves
We take it for granted that plants have green leaves for photosynthesis, but green vegetation may be a reflection of the solar spectrum on the Earth. Our sun is a G-class (yellow) star, which emits a peak spectrum in the visual range. Additionally, the Earth's atmosphere has a significant effect on the light reaching the ground, making it ideal for plants to absorb in blue or red. What if we discover a habitable planet around a different star? NASA and CalTech have already looked into this possibility. On a planet orbiting an F-class (yellow-white) star, which is somewhat hotter than the sun, photosynthesis will most likely concentrate on blue and green wavelengths, because that's where the energy peak will be. Leaves there will reflect mostly in yellow, orange, and red. It would be "fall" year-round, at least based on the coloration of Earth's vegetation.

As seasons unravel ... I muse that, even though the tree has lost its leaves, it may be haunted by the memory of their warmth.

"A plate of poetry, please: Leaves and lovers", Varsity Online, May 23, 2016
There is not a single leaf which is a mere ornament; all contribute to the fruitfulness of the earth, and the support of its inhabitants.
CHRISTOPH CHRISTIAN STURM
Reflections on the Works of God and of His Providence
Now Autumn's fire burns slowly along the woods,
And day by day the dead leaves fall and melt.
WILLIAM ALLINGHAM
"Autumnal Sonnet", Day and Night Songs
Every leaf speaks bliss to me
Fluttering from the autumn tree.
EMILY BRONTË
"Fall, Leaves, Fall"
The gentle wind, a sweet and passionate wooer,
Kisses the blushing leaf.
HENRY WADSWORTH LONGFELLOW
"Woods in Winter"
Each particle of matter is an immensity, each leaf a world, each insect an inexplicable compendium.
JOHANN CASPAR LAVATER
Physiognomy
Listen! the wind is rising, and the air is wild with leaves, we have had our summer evenings, now for October eves.
HUMBERT WOLFE
P.L.M.: Peoples, Landfalls, Mountains
A tangerine and russet cascade of kaleidoscopic leaves, creates a tapestry of autumn magic upon the emerald carpet of fading summer.
JUDITH A. LINDBERG
The Organic View
The stripped and shapely
Maple grieves
The ghosts of her
Departed leaves.
JOHN UPDIKE
A Child's Calendar
A gust of wind rattles the window, and I look out. Leaves are whooshing all over the place, flying past horizontally as if they have engines of their own.
KATE MESSNER
The Brilliant Fall of Gianna Z.
Do you know why the leaves change colour?... Before a tree sheds a leaf it pumps it full of all the poison it can't rid itself of otherwise. That red there--that's a man's skin blotching with burst veins after an assassin spikes his last meal with roto-weed. The poison spreading through him before he dies.
MARK LAWRENCE
Emperor of Thorns
Are ye the ghosts of fallen leaves,
O flakes of snow,
For which, through naked trees, the winds
A-mourning go?
JOHN BANISTER TABB
"Phantoms", Poems
And the wind is rising squally and loud
With many a stormy token--
Playing a wild funereal air,
Through the branches bleak, bereaved, and bare,
To the dead leaves dancing here and there.
THOMAS HOOD
"The Forge", Poems of Wit and Humour
And softly through the altered air
Hurries a timid leaf.
EMILY DICKINSON
"Indian Summer"
Ah, the pretty whisperers! It was very well
When the leaves were thick and green, awhile ago--
Leaves are secret-keepers; but since the last leaf fell
There is nothing hidden from the eyes below.
SUSAN COOLIDGE
"Secrets", Verses
The foliage has been losing its freshness through the month of August, and here and there a yellow leaf shows itself like the first gray hair amidst the locks of a beauty who has seen one season too many.
OLIVER WENDELL HOLMES
"The Seasons", Pages from An Old Volume: A Collection of Essays
The woods are hush'd, their music is no more;
The leaf is dead, the yearning past away;
New leaf, new life--the days of frost are o'er;
New life, new love, to suit the newer day:
New loves are sweet as those that went before:
Free love--free field--we love but while we may.
ALFRED TENNYSON
Idylls of the King
As fall the light autumnal leaves, one still the other following, till the bough strews all its honors on the earth below.
DANTE ALIGHIERI
The Vision; or Hell, Purgatory, and Paradise
A chaplet of leaves crowns the victor.
