Indian Hawthorn that’s everywhere now, not the Hawthorn of Proust however. Here’s a sentence from Proust mentioning Hawthorns…for your ‘entertainment’?:
“I found the whole path throbbing with the fragrance of hawthorn-blossom. The hedge resembled a series of chapels, whose walls were no longer visible under the mountains of flowers that were heaped upon their altars; while underneath, the sun cast a square of light upon the ground, as though it had shone in upon them through a window; the scent that swept out over me from them was as rich, and as circumscribed in its range, as though I had been standing before the Lady-altar, and the flowers, themselves adorned also, held out each its little bunch of glittering stamens with an air of inattention, fine, radiating ‘nerves’ in the flamboyant style of architecture, like those which, in church, framed the stair to the rood-loft or closed the perpendicular tracery of the windows, but here spread out into pools of fleshy white, like strawberry-beds in spring. How simple and rustic, in comparison with these, would seem the dog-roses which, in a few weeks’ time, would be climbing the same hillside path in the heat of the sun, dressed in the smooth silk of their blushing pink bodices, which would be undone and scattered by the first breath of wind.
“But it was in vain that I lingered before the hawthorns, to breathe in, to marshal before my mind (which knew not what to make of it), to lose in order to rediscover their invisible and unchanging odour, to absorb myself in the rhythm which disposed their flowers here and there with the light-heartedness of youth, and at intervals as unexpected as certain intervals of music; they offered me an indefinite continuation of the same charm, in an inexhaustible profusion, but without letting me delve into it any more deeply, like those melodies which one can play over a hundred times in succession without coming any nearer to their secret. I turned away from them for a moment so as to be able to return to them with renewed strength. My eyes followed up the slope which, outside the hedge, rose steeply to the fields, a poppy that had strayed and been lost by its fellows, or a few cornflowers that had fallen lazily behind, and decorated the ground here and there with their flowers like the border of a tapestry, in which may be seen at intervals hints of the rustic theme which appears triumphant in the panel itself; infrequent still, spaced apart as the scattered houses which warn us that we are approaching a village, they betokened to me the vast expanse of waving corn beneath the fleecy clouds, and the sight of a single poppy hoisting upon its slender rigging and holding against the breeze its scarlet ensign, over the buoy of rich black earth from which it sprang, made my heart beat as does a wayfarer’s when he perceives, upon some low-lying ground, an old and broken boat which is being caulked and made seaworthy, and cries out, although he has not yet caught sight of it, “The Sea!”
