August 16, 1856

in Thoreau’s Journal:

What a variety of old garden herbs – mints, etc. – are naturalized along an old settled road, like this to Boston which the British travelled! And then there is the site, apparently, of an old garden by the tanyard, where the spearmint grows so rankly. I am intoxicated with the fragrance. Though I find only one new plant (the cassia), yet old acquaintances grow so rankly, and the spearmint intoxicates me so, that I am bewildered, as it were by a variety of new things. An infinite novelty. All the roadside is the site of an old garden where fragrant herbs have become naturalized, – hounds-tongue, bergamot, spearmint, elecampane, etc. I see even the tiger lily, with its bulbs, growing by the roadside far from houses (near Leighton’s graveyard).

I think I have found many new plants, and am surprised when I can reckon but one. A little distance from my ordinary walk and a little variety in the growth or luxuriance will produce this illusion. By the discovery of one new plant all bounds seem to be infinitely removed.
