 Herbs and Spices

Last revised February 11, 2010

Herb production may be for culinary purposes (food flavoring), for scents and fragrances (potpourris), for medicinal uses or others (dyes, dried floral arrangements etc). Herb producers often grow for all these markets, and some herbs may be used for all these purposes.
Some of the most popular culinary herbs grown commercially and by home gardeners and hobbyists are: basil, cilantro (coriander), chervil, dill, oregano, mint, parsley, rosemary, sage, tarragon and thyme.

Information on herbs may be obtained from library references, seed catalogs, special garden books and some public bulletins. Because of the highly specialized nature of herb production, public bulletins are minimal and the information contained in them is very general. For these reasons, this document will only give a limited amount of general information on culinary herbs or those that may be used for culinary and other uses.

Medicinal herbs are so specialized and often controversial that mention of their use will be ancillary, and only if the herb is also used for culinary purposes. Two valuable references on medicinal herbs are The Honest Herbal (1993) and Herbs of Choice (1994), both by Varro E. Tyler, Ph.D., and published by Haworth Press Inc., New York City. Dr. Tyler was for 20 years the Dean of the School of Pharmacy and Pharmaceutical Sciences at Purdue University. He has published extensively on this subject and is a nationally and internationally recognized expert on medicinal herbs.

Valuable web resources on herbs in general include the Herbs Directory operated by the Dept. of Horticulture at Pennsylvania State University, and Herb/Spice Industry from the Alberta Ministry of Agriculture, Food, and Rural Development, Herb Growing and Marketing Network , International Herb Assoc., and Growing and Selling Fresh-Cut Herbs. Books include 'Culinary Herbs' by Ernest Small, published by the National Research Council of Canada, and 'The Cornell Book of Herbs and Edible Flowers' by Jeanne Mackin (Cornell Coop. Extension), and 'Rodale's Illustrated Encyclopedia of Herbs', from Rodale Press. Newsletters include 'The Herb, Spice, and Medicinal Plant Digest', edited by L.E. Craker, Dept. of Plant & Soil Sciences, Univ. of Massachusetts, Amherst, MA 01003, and Herb World, from The Herb Growing and Marketing Network.

Herbs most commonly grown in the Pacific Northwest are mostly adapted to sunny, warm locations. Those listed are generally adapted to a wide range of soil types. Herbs need minimal irrigation, particularly as they mature and their aromatic and flavor compounds are developing.


Fertilizer requirements are basic, usually being limited to N, P, and K. In some cases lime is needed to maintain soil pH near neutral, but most are adapted to a wide range of soil pH (5.5-7.5). Nitrogen is usually applied at 75-150 lb/acre depending on the harvested product (leaves or seeds). Timing of nitrogen applications is dependent on whether the species is annual, biennial or perennial. Phosphorous is applied at 50-200 lb/acre and potassium at 0-150 lb/acre depending on the above-mentioned characteristics of the crop and soil test.


Harvest timing and equipment are also specific to the herbs being produced. Often, considerable hand labor is required in production and harvest operations, particularly when the marketable leafy portions of some must be separated from stems, or where only the floral parts are required. Small motorized clippers are often used as harvester aids. Sometimes, when seeds are the marketable product, combines, often specially adapted, are used. Where the distilled oil is the marketable product, there are those who provide custom distillation using portable or stationary stills.

The harvested product often requires immediate special handling such as drying, separation of leaves or seed, and temporary packaging storage to best preserve its color, aroma, flavor, the integrity of its appearance and sanitary condition.


The following is a listing of some of the herbs that may be produced in the Pacific Northwest, a brief description, their taxonomic classification, common synonyms, general uses, and production considerations.

Five characteristics or cultural practice considerations are coded and separated by a slash (/). The codes are represented as follows:

Life cycle: annual (a)/ biennial (b)/ perennial (p).
Established by: Seed (s)/ divisions (d)/ cuttings (c)/ or transplants (t).
Planting time: Spring (sp)/ after frost danger (af)/ fall (fa).
Plant size: as listed next.
Preferred site: Full sun (fs)/ part shade (ps)/ also a potted plant (pot).

Uses are represented by the abbreviations: Flavorings (FLA), tea (TEA), fragrances (FRA), ornamental (ORN), folk medicine (MED), and all of the above (ALL).

Few pesticides are registered for use in herb production. In some cases special restrictions apply to the use of pesticides in products that will be concentrated (distilled or processed in certain ways).


The Pacific Northwest Weed Control Handbook has no control entries for this crop. Cultivate as often as necessary when weeds are small. Proper cultivation, field selection and rotations can reduce or eliminate the need for chemical weed control.


The Pacific Northwest Insect Control Handbook has no control entries for this crop. Proper rotations and field selection can minimize problems with insects.


The Pacific Northwest Disease Control Handbook has no control entries for this crop. Proper rotations, field selection, sanitation, spacings, fertilizer and irrigation practices can reduce the risk of many diseases. Fields can be tested for presence of harmful nematodes. Using seed from reputable sources reduces risk from "seed-borne" diseases.
