Gas Plant is a 2′-3′ plant that is extremely long-lived but slow to establish itself. It has dark green glossy leaves, and white star-shaped flowers and is strongly scented. The simplest growing method is to seed outdoors in the fall. Otherwise you can cold stratify in damp peat moss. As the seeds germinate place them in damp peat moss at room temperature for one month before potting up seedlings. Seed germinates over many months.
