Grow in average, medium moisture, well-drained soil in full sun. Prefers evenly moist, fertile soils that do not become soggy. Does best in northern climates where the nights are cool.

Can be grown from seed but takes several years to flower.
This gas plant variety is an aromatic, upright, clump-forming, woody based, herbaceous perennial that features rigid, vertical stems typically growing 2-3' tall which are topped by erect, terminal spires (racemes) of 5-petaled, 1" long, pale to deep purplish-pink flowers with darker lines on the petals. Slightly fragrant flowers bloom only for a brief period (approximately two weeks) in late spring to early summer, and give way to star-shaped seed pods which are attractive in fall if left on the plant. Elegant, glossy, light green, pinnate leaves are attractive throughout the growing season and possess a pleasant lemony scent when rubbed or crushed. Foliage also contains an oil that, in some individuals, can cause a skin rash. In hot weather, old flowers or seed pods emit a flammable oil which, on a windless summer evening, can be ignited with a match, resulting in a brief vapor burn which is harmless to the plant... hence the common name of gas plant.
No serious insect or disease problems. Support is generally unnecessary due to strength of woody based stems.
Excellent specimen or group planting for perennial borders, especially effective with day lilies, campanulas or iris.
