this one has the best aroma and taste compared to other cymbopogon. Plants really need warm weather to do well they do not do well in cool wet summer climates.They cannot take -6 C at all, C.Citratus can be grown as perrenial in zone 8B and maybe 8A. Flexuosus cannot take light freezes, bring them indoors and overwinter them on a cool spot or in front of a sunny window.

Keys to succes are humidity, warmth and water. They can be grown in full sun or shade. Some people say they could be reliable houseplants ( i believe cymbopogon are good candidates) , but if you want to try this do not take outdoor plants indoors , you are better off to grow them from seed to ensure they are pest free indoors.
