Henbane, Black (Hyoscyamus niger), organic 

Hyoscyamus niger
One of the most fascinating and insidious plants one can grow from seed, the flowers are deeply attractive. Henbane is actually a self-seeding annual in the temperate zone. The entire plant contains toxic alkaloids, most concentrated in the seeds, which are of course not recommended for internal use but prove to be potently pain relieving when used externally. The method is to extract the seeds with alcohol, then evaporate the alcohol away in hot salve oil, which leaves behind the pain relieving effect. To grow henbane, strew the seed on the surface of soil or in pots in the fall or early spring and press in.

A rather pretty annual or biennial plant with large gray green leaves and spikes of yellow flowers. This plant is an interesting conversation piece and makes an different addtion to a herb garden or border plant.

Warning. Black henbane is a very poisonous plant. All parts of the plant are toxic so care should be taken when growing this plant. Do not grow this plant if there are children or pets using the garden.

Description.

Henbane is actually rather a pretty plant. It has large soft oval to lance shaped gray green leaves which are thickly felted and usually toothed. It sends up sprays of slightly arching stems with pairs of opposite leaves with no stalks that are anywhere from 2 to 4 feet in height. The stems are stout and can be slightly woody especially at the base. The flowers begin to appear in early to mid summer and are arranged on a arching stems. The lower flowers are shortly stalked while the upper ones are crowded together on one side of the stem. All the flowers are dull to mid yellow in color with purple centers and are about 1 inch across. The scent is reported as powerful, oppressive and even nauseous. The seeds ripen in interesting pitcher shaped calyx vessels bulbous at the lower end with spikes surrounding the top. The arching stems of seed carapaces are very attractive.

Henbane is a most interesting plant in that it can be either an annual or a biennial (two years) both from the same seed stock. Some research has suggested that it depends on where on the arching stem of flowers the seeds come from determines which the plant will be, lower on the stem (earlier flowers) produces biennials while higher ones are annuals, however this is not definitive.

Annual forms tend to be smaller growing to 2 feet in height and flowering in the first year. They are not as strong and stems tend to be single not branched. The leaves are not as hairy and the flowers are fully yellow most often without purple markings. These plants tend to flower in July and August.

The biennial form produces a rosette of leaves in the first year which disappear in winter. The plant produces a fleshy taproot that looks similar to a parsnip. In spring the leaves return and tend to be larger often 12" in length and covered with soft hairs that secrete a resin that can make the leave feel clammy and sticky . The flower stems arise in early spring and rapidly branch. They can reach 3-4 feet in height and also have much larger leaves than the annual form often 9-10" in length. The leaves are pale green with a broad conspicuous mid-rib. The flowers are the same size and shape but the yellow flowers are usually marked with a close network of lurid purple veins, although some plants do not have this feature. Seed capsules are the same as is the flower scent.

Growing

Modern herbal states that henbane seeds are often obstinate, most often they germinate well and easily but on occasion they will refuse to germinate for several months. We have never had a problem on the farm germinating the seeds and so far cannot confirm that location of seed on the stem produces annual or biennial plants, they seem arbitrarily mixed. Sowing directly in the ground has been recommended but we have had no problem transplanting seeds provided that they are potted not bare rooted.
