Comments: Gas Plant produces fragrant flowers and foliage. The name Gas Plant refers to the gases the plant gives off. These gases can sometimes be ignited. The plant is long-lived and is not easily transplanted once it has become established. Seed pods can be used for winter decoration. The plant grows best in full sun or partial shade and in a well-drained soil. Touching the plant may result in dermatitis.
Propagation: Propagation is by root cuttings or seed. Plant seed outdoors in the fall, however it may take 4 years for seed-grown plants to bloom. Root cuttings may be difficult to do. Make 3 inch long root cuttings then put them in pots of sandy soil. When root and shoot formation have occurred, put the plants in the garden.
