About

Peganum harmala, commonly called wild rue, Syrian rue, African rue, esfand or espand, or harmel (among other similar pronunciations and spellings), is a perennial, herbaceous plant, with a woody underground rootstock, of the family Nitrariaceae, usually growing in saline soils in temperate desert and Mediterranean regions. Its common English-language name came about because of a resemblance to rue (to which it is not related). Its seeds contain a high concentration (at least 5.9% by weight) of diverse beta-carboline alkaloids.

It has deep roots and a strong smell, finely divided leaves, white flowers rich in alkaloids, and small seed capsules containing numerous dark, oily seeds.

Where it grows

It grows in dry areas in the United States. It can be considered a halophyte.
