Dictamnus is a genus of flowering plant in the Rutaceae family, commonly known as the burning bush or gas plant. It is the only genus in its group and is known for its unique ability to emit a flammable exudate from its flowers and leaves, which can ignite when exposed to open flame.

Description

Dictamnus plants are perennial herbs, known for their woody rootstock and beautiful, star-shaped flowers. The leaves are pinnate, with lanceolate leaflets that are glossy and have a leathery texture. The flowers are borne in racemes and are typically white or pink with a pleasant aroma. The fruit is a capsule containing several seeds.

Distribution and habitat

Dictamnus is native to southern Europe, northern Africa, and northern and central Asia. It thrives in open, sunny habitats, including dry, rocky hillsides and woodland edges.

Cultivation and uses

Dictamnus is cultivated as an ornamental plant in gardens for its attractive flowers and unique flammable properties. It prefers well-drained soil and a sunny location. Care should be taken when planting, as the plant can cause skin irritation or allergic reactions in some people.

Chemical properties

The flammable substance produced by Dictamnus is due to the presence of volatile oils in the plant's glands. These oils can vaporize on warm days, creating a combustible mixture in the air around the plant.

In culture

The unusual flammable characteristic of Dictamnus has made it a subject of curiosity and folklore. It has been mentioned in various historical texts and is sometimes used in traditional medicine, although its use is limited due to its irritant properties.
