The poisoning henbane, and the mandrake dread.
Drayton.

That there are felonious as well as philanthropic flowers, plants that are actively malignant in their relation to mankind, has always been a popular belief. The upas-tree, for example, has given rise to many gruesome stories; and the mandrake, fabled to shriek when torn from the ground, has played a frequent part in poetry and legend; not to mention the host of noxious weeds, the "plants at whose names the verse feels loath," as Shelley has it:

And thistles, and nettles, and darnels rank,
And the dock, and henbane, and hemlock dank.

The felons, however, of whom I would now speak are not the plants that seem merely foul and repulsive, such as the docks and nettles, the broom-rapes, toothworts, and similar ill-looking parasites, but rather the bold bad outlaws and highwaymen, the "gentlemen of the road," who, however deleterious to human welfare, have a sinister beauty and distinction of their own, and are thus able to fascinate us. Prominent among these is the clan of the nightshades, to which the mandrake itself belongs, and which has several well-known representatives among British flowers; above all, the deadly nightshade, or dwale, as it is better named, to distinguish it from smaller relatives that are wrongly described as "the deadly." So poisonous is the dwale that Gerarde three centuries ago exhorted his readers to "banish these pernicious plants out of your gardens, and all places near to your houses, where children do resort;" and modern writers tell us that the plant is "fortunately" of rare occurrence. But threatened plants, like threatened men, live long; and the dwale, though very local, may still be found in some abundance: there are woods where it grows even in profusion, and, pace Gerarde, rejoices the heart of the flower-lover, for in truth it has a strange and ominous charm, this massive grave-looking plant with the large oval leaves, heavy sombre purple blossoms, and big black "wolf-cherries."[16]

Next to the dwale in the nightshade family must rank the henbane, a fallen angel among wildflowers; for its beauty is of the sickly and fetid kind, which at once attracts and repels. It is curious that in the lines from Shelley's "Sensitive Plant" the epithet "dank" should be given to the hemlock, to which it is quite unsuited, rather than to the henbane, where its appropriateness could not be questioned; for the stalk, leaves, and flowers of the henbane are alike clammy to the touch. Presumably this uncertain and sporadic herb has become rarer of late years; for whereas it is frequently stated in books to be "common in waste places," one may visit hundreds of waste places without a glimpse of it. In the Flora of the Lake District (1885) Arnside is given as one of its localities; but I was told by a resident that he had only once seen it there, and then it had sprung up in his garden.

It is in similar places that the thorn-apple, another cousin to the nightshade, is apt to make its un-invited appearance; less a felon, perhaps, than a sturdy rogue and vagabond among flowers of ill repute. A year or two ago, I was told by the holder of an allotment-garden that a great number of thorn-apples were springing up in his ground; and knowing my interest in flowers he sent me a small basketful of the young plants, which, rather to my neighbours' surprise, I set out in a row, like lettuces, in a corner of my back-yard. There they flourished well, and in due course made a fine show with their trumpet-shaped white flowers and the big thorny capsules whence the plant takes its name. It is not a bad-looking fellow, but awkward and hulking, and quite devoid of the sickly grace of the henbane or of the bodeful gloom of the dwale.

Passing now to the handsome but acrid tribe of the ranunculi, and omitting the poisonous but interesting baneberry, of which I have already spoken, we come to two formidable plants, the hellebore and the monk's-hood, which have been famous from earliest times for their dangerous propensities. The green hellebore, though in Westmorland named "felon grass," is a less felonious-looking flower than its close kinsman the fetid hellebore, whose general appearance, owing to the crude pale green of its purple-tipped sepals, and the reluctance of its globe-like buds to expand themselves fully, is one of insalubrity and unripeness. But it is a plant of distinction, some two or three feet in height; and as it flowers before the winter is well past, it can hardly fail to arrest attention in the few places where it is to be found: in Arundel Park, in Sussex, it may be seen growing in close conjunction with the deadly nightshade—a noteworthy pair of desperadoes.

The other malefactor of the ranunculus family is the aconite, or monk's-hood, a poisonous but very picturesque flower with deep blue blossoms, which takes its name from the hood-like appearance of the upper sepal. "It beareth," Gerarde tells us, "very fair and goodly blew floures in shape like an helmet, which are so beautiful that a man would thinke they were of some excellent vertue." A traitor, a masked bandit it is, of such evil reputation that, according to Pliny, it kills man, "unless it can find in him something else to kill," some disease, to wit; and thus it holds its place in the pharmacopoeia.

The umbellifers include a number of outlaws such as the water-dropworts and cowbane; but among the dangerous members of the tribe there is only one that attains to real greatness, and that of course is the hemlock, a poisoner of old-established renown, as witness the death of Socrates. "Root of hemlock digg'd i' the dark" is one of the ingredients in the witches' cauldron in Macbeth, and the hemlock's name has always been one to conjure with, which may account for the fact that several kindred, but less eminent plants unlawfully aspire to it, and are erroneously thus classed. But the true hemlock is unmistakable: the stout bloodspotted stem distinguishes it from the lesser crew; its finely cut fernlike leaves are exceedingly beautiful; and it is of stately habit—I have seen it growing to the height of nine feet, or more, in places where the surrounding brushwood had to be overtopped.

Let us give their due, then, to these outlaws of whom I have spoken, these Robin Hoods of the floral world. Bandits and highwaymen they may be; but after all, our woods and waysides would be much duller if they were banished.
