Nettles are much used in the neighbourhood of London to pack plums and other fruit with bloom on them, so that in some market gardens they are not only not destroyed, but encouraged, and even cultivated. And this is an old practice; Lawson's advice in 1683 was--"For the gathering of all other stone-fruit, as Nectarines, Apricots, Peaches, Pear-plums, Damsons, Bullas, and such like, . . . in the bottom of your large sives where you put them, you shall lay Nettles, and likewise in the top, for that will ripen those that are most unready" ("New Orchard," p. 96).
The "Nettle of India" (No. 5) has puzzled the commentators. It is probably not the true reading; if the true reading, it may only mean a Nettle of extra-stinging quality; but it may also mean an Eastern plant that was used to produce cowage, or cow-itch. "The hairs of the pods of Mucuna pruriens, &c., constitute the substance called cow-itch, a mechanical Anthelmintic."--LINDLEY. This plant is said to have been called the Nettle of India, but I do not find it so named in Shakespeare's time.
In other points the Nettle is a most interesting plant. Microscopists find in it most beautiful objects for the microscope; entomologists value it, for it is such a favourite of butterflies and other insects, that in Britain alone upwards of thirty insects feed solely on the Nettle plant, and it is one of those curious plants which mark the progress of civilization by following man wherever he goes.[178:1]
But as a garden plant the only advice to be given is to keep it out of the garden by every means. In good cultivated ground it becomes a sad weed if once allowed a settlement. The Himalayan Böhmerias, however, are handsome, but only for their foliage; and though we cannot, perhaps, admit our roadside Dead Nettles, which however are much handsomer than many foreign flowers which we carefully tend and prize, yet the Austrian Dead Nettle (_Lamium orvala_, "Bot. Mag.," v. 172) may be well admitted as a handsome garden plant.
