True oregano

  • Oregano (Origanum vulgare) – This is also known as true oregano or Italian oregano commonly used in pizzas and tomato sauces. Its best-known variety is the Greek oregano (Origanum vulgare var. hirtum). Another variety is the golden oregano (Origanum vulgare var. aureum), which got its name for its gold-colored foliage.
  • Marjoram (Origanum majorana) – This variety is commonly used in Southern Europe and the Middle East. This has a milder and less spicy flavor compared to Greek oregano.
  • Syrian oregano (Origanum syriacum or Origanum maru) – This is a common ingredient of the Middle Eastern spice mixture za’atar, which also includes ground sumac and sesame seeds.


  • Mexican oregano (Lippia graveolens) – This is a member of the verbena family that tastes like Greek oregano. This is common in Mexico and the Southwestern United States.

The ideal planting time for oregano is 6 to 10 weeks before the last spring frost. The climate in Texas makes it a suitable place to plant oregano.

  • Chlorpyrifos (CPS) – This is an organophosphate pesticide used to kill insects and worms. 
  • Diphenylamine (DPA) – This is a post-harvest scald inhibitor for apples, which means using DPA prevents apples from getting brown spots when removed from storage.
  • Acetamiprid – This is an odorless insecticide.
  • Deltamethrin – This is a pyrethroid ester insecticide.
  • Pyriproxyfen – This is a pesticide effective against insect pests.
  • Cyfluthrin – This is a pyrethroid insecticide and common household pesticide.


Oregano is native to the Mediterranean and Central Asia. It is a perennial plant in places where the climate is hot and dry. However, oregano cultivars that have adapted to cold weather are annuals because this plant cannot survive the winter.

Put freshly-cut oregano you did not use inside a plastic bag and store it in the refrigerator. This way, you can still use the oregano but not after four days. Place a moist paper towel in the bag and leave some air in to extend its freshness to seven days.
