The narrow foliage of lemongrass ranges from blue-green to gold, and the flowers are white, cream, or green depending on the plant’s age. Generally, there will be more colours of purple and blue in the base of the plant closest to its root source. Younger lemongrass will display a sweet tropical citrus aroma reminiscent of natural fruit loops. The stalk and bulb will be tender to the touch and knife. The older the plant, the more fibrous and less flavourful.
