The life of one plant would be affected by another. Rue was definitely hostile to basil, rosemary to hyssop, but coriander, dill and chervil lived on the friendliest of terms[.]
(uncountable) Leaves from the plant, used as an herb in cooking, which have a mild flavor of anise.

2017, Alice Arndt, Seasoning Savvy: How to Cook with Herbs, Spices, and Other Flavorings[1], CRC Press, →ISBN:
