Description

Gas Plant is slow to establish but very long-lived as a bushy, upright clump with fragrant glossy green leaves. Showy spikes of spidery-looking white flowers appear in early summer.  On still days a match held below the spike will ignite a burst of methane gas. Gas plant does not transplant well, and once established should not be divided in the garden. Start new plants from seed sown outdoors in the fall, and allowed to go through the winter for cold stratification. They can take 2-4 years before they will bloom. Prefers moist, well-drained, slightly alkaline soils but will tolerate some drought once established. It does best in climates with cooler summer nights.

Flowers and foliage cause skin rash in some individuals.
