How to recognize it

Key identification clues

  • Five petals form an uneven flower, often with four petals above and one below.
  • The pale pink flowers in these photographs have dark branching veins and long projecting stamens.
  • Several oval, finely toothed leaflets share a central stalk.

Where and when to look

Look for upright flowering spikes in sunny openings and established gardens in late spring or early summer. A clump can persist for years after planting. In North America its presence at a site does not, by itself, establish how it arrived.

Compare similar plants

The comparison photograph shows Winged Burning Bush, a woody shrub with red autumn leaves and small greenish flowers in spring. Gas Plant is an herb with compound leaves and prominent pink or white flowers. Both plants share the name “Burning Bush.”

A closer look

Flower details

Trace one dark vein outward from the throat of the flower. The petals spread unevenly around the curved stamens, and flowers that have yet to open remain in bud farther up the stalk.

Leaves & stems

Each compound leaf is made up of several leaflets on a shared stalk. The close-up shows their pointed tips and fine teeth. The foliage belongs to the rue family, which also includes citrus.

Whole plant & habitat

A plant sends up several leafy stems from the base. From a distance, the flowering shoots look like separate spikes. Closer views show the flowers attached individually along each stem.

Range & sightings

Native to parts of Europe and Asia and introduced in North America. NC State Extension lists Michigan, New York, and Vermont. Its occurrence in gardens is more widespread than these records of introductions.

Documented U.S. records in the cited sources
MI, NY, VT

The sightings map shows submitted observations, which can include cultivated plants.

Where the name comes from

The name Gas Plant comes from volatile oils released by its flowers and developing fruits. On a hot, still day the vapors can be flammable. The visible clues for identification are the veins, curved stamens, and divided leaves.
